The Best Firm Mattress of 2025

Sleep Foundation
Why Trust Us
Our mission to create a healthier, more well-rested world demands that our product reviews be best-in-class. You won’t find more expertise on mattresses and sleep products anywhere else.
The Sleep Foundation product testing team uses an industry-leading evaluation process paired with real world consumer feedback to come up with objective recommendations so that you can feel confident in your product decisions.
Firm mattresses are popular for a good reason: They make for sturdy, supportive, and durable beds that promote better spinal alignment, reduce heat buildup, and offer consistent support night after night. In the guide below, we’ll share our picks for the best firm mattresses and cover all of the things you’ll want to keep in mind as you’re shopping.
To find the best firm mattress, our Seattle-based testing team looked to our database of more than 2,000 beds. From there, it was all about prioritizing high firmness options, user feedback and hands-on reviews, and researching construction and performance to create our final list.
How We Tested the Best Firm Mattress
Testing Criteria for Firm Mattresses
When it comes to testing mattresses, we always rely on our research methodology, but we decided on a few key factors to keep in mind when creating our list of the best firm beds:
- Robust Support: The best firm mattresses feel flat and even, allowing you to lie on your side, back, or stomach without sinking too deeply — regardless of what sleeping position you prefer.
- Strong Perimeter: A firm mattress should push back against your weight and feel secure when you sit or sleep along its edges. This is also known as edge support, which we regularly research in our testing process.
- Ease of Movement: Many of the best firm mattresses feel responsive and bouncy, so you shouldn’t feel stuck when moving across their surfaces or changing sleep positions. A good, firm mattress will allow for better ease of movement, whereas a softer one will conform more closely to your body.
How We Evaluated
To kick off our testing process, we first looked to our database of more than 2,000 mattresses. Looking at beds with high firmness options (firm, medium firm, and extra firm), we also made sure each bed had the following:
- A test lab score of 7.5 or higher (the only exception here is the Leesa Plus Hybrid, which has a medium firmness score of 6, but also provides exceptional support)
- Above average scores for edge support and ease of movement
- A firmness level of 7 or higher
From there, we were able to narrow things down, taking our picks in for testing at our lab. We provided scores for other important performance categories, like motion isolation, pressure relief, temperature control, and durability, ultimately coming up with our final list and providing accolades for each of them.

Best Firm Mattress Overall
8.2 /10 Test Lab Score
Plank Firm Luxe
High-end flippable bed that’s firm on one side, and even firmer on the other.
Key Details
- Who it’s best for: Back and stomach sleepers who weigh more than 230 pounds, as well as hot sleepers.
- Feel: Both sides feel exceptionally firm with minimal contouring and strong pushback.
- What it’s made of: High-density foam comfort layers on each side and a shared support core of pocketed coils.
- What we don’t like: Most side sleepers on our team found the mattress too firm.
Scoring & Reviews
The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
The Plank Firm Luxe has lower ratings for motion isolation than most hybrid mattresses.Because of its firmness and bouncy coils, the Plank Firm Luxe has limited ability to absorb motion that happens when there’s movement on another part of the mattress. With less cushioning, the extra firm (9) side tends to permit more motion transfer.Couples who are worried about sleep disruptions from movement may prefer a mattress with foam materials that better absorb vibrations.
Pressure Relief
A lack of pressure relief is one of the main drawbacks of the Plank Firm Luxe Mattress. The firm (7) side has limited ability to cradle the joints, and the extra firm (9) side offers even less cushioning.That said, this mattress isn’t built to hug sleepers and provide a cloud-like feel. Instead, it is meant precisely for people who need or prefer a harder sleep surface. Based on our testing, the mattress appeals most to back and stomach sleepers.
Temperature Control
We found that the Plank Firm Luxe offers above-average temperature control. None of our testers complained about overheating, especially when using the extra firm (9) side. Since sleepers don’t sink into the mattress, there’s plenty of room for airflow around the skin, which helps the body naturally regulate its temperature.For hot sleepers who want extra cooling features, the optional cooling cover can make it even easier to avoid waking up in a sweat.
Edge Support
Because of its firmness, the Plank Firm Luxe has excellent edge support. The extra firm (9) side of the mattress is particularly supportive around the perimeter, but both sides allow you to comfortably sit or sleep near the edge of the bed. Strong edge support also makes getting in and out of bed easier.
Ease of Movement
Our testers had very few problems when they wanted to move around on the surface of the Plank Firm Luxe. The firmness level means that you don’t sink into the mattress, so there’s little resistance when you want to adjust your body’s positioning. The bounce of the coils also contributes to the high marks for ease of movement for the Plank Firm Luxe.
Durability
Full Breakdown
The Plank Firm Luxe — also known as the Plank Luxe Hybrid — is a flippable mattress with a firm (7) feel on one side and an extra firm (9) feel on the other. The latter is one of the firmest, most supportive surfaces our team has personally tested, but we also found the softer side highly stable and well-suited to people who weigh more than 230 pounds – particularly back and stomach sleepers.
How It Performed
During our hands-on tests, the Plank Firm Luxe earned its most favorable ratings from back and stomach sleepers weighing more than 230 pounds. Most testers agreed the firm side was more comfortable, though some of our stomach sleepers in this weight group received more support from the extra firm feel.
We also gave the mattress high marks for edge support and ease of movement. The coils create a responsive feel on both sides, allowing our testers to move across the mattress without feeling trapped or stuck, and each person felt stable when sitting along the perimeter. Temperature control was another performance area where the Plank Firm Luxe excelled, especially with the phase change panel upgrade.
Construction Breakdown
The firm side of the Plank Firm Luxe contains a top layer of fiber padding, followed by two polyfoam layers. Our testers noticed light cushioning on this surface, resulting in even weight distribution and minimal sinkage. The extra firm side forgoes one of the underlying foam layers. As a result, we experienced no sinkage whatsoever on this surface. A shared support core of pocketed coils reinforces each side, resulting in strong pushback whenever one of our testers got in and out of bed.
A cover made from a quilted cotton-microfiber blend encases the entire mattress. This material is fairly breathable, and air circulates freely through the coil layer, so we detected minimal heat buildup during our temperature control tests. If you are an exceptionally hot sleeper, we recommend upgrading the mattress with a phase change panel sewn into both surfaces. Our testers noticed cooling bursts from these panels, which reduced heat buildup and kept the mattress at a comfortable temperature.
Trial, Shipping, and Warranty
Brooklyn Bedding offers twelve sizes, including options for short queen and RV beds, and the company ships free to customers in the contiguous U.S. A 120-night sleep trial and lifetime warranty back Plank Firm Luxe purchases.

Firmer WinkBed
High end hybrid bed providing ample support, cushion, and cool sleep.
Key Details
- Who it’s best for: Back and stomach sleepers who weigh at least 130 pounds.
- Feel: Supportive design with strong pushback against the weight in your midsection.
- What it’s made of: Dense foam layers encased in a Euro-top cover over multi-z0ne pocketed coils.
- What we don’t like: People who weigh less than 130 pounds may not receive enough cushioning.

Full Breakdown
The WinkBed is a luxury hybrid available in four different firmness levels. After personally testing each design, we’re recommending the Firmer WinkBed (7) for anyone seeking a firm, supportive mattress. Our team was particularly impressed by the zoned coil system, which provided excellent reinforcement and pushback during our tests for ease of movement and edge support. The adaptive foam layers also contour evenly to reduce pain and pressure in the shoulders, lower back, and hips.
How It Performed
We noticed excellent overall stability when testing the Firmer WinkBed for edge support, and our testers could move across the mattress’ surface with relative ease. Temperature control was another highlight of our tests. We attribute the Firmer WinkBed’s excellent cooling to its moisture-wicking cover, gel-infused foam layer, and steady airflow throughout the coil system.
The mattress was particularly comfortable for the back and stomach sleepers on our team who weigh at least 130 pounds. Our side sleepers weighing more than 230 pounds also found the Firmer WinkBed sufficiently supportive. Lighter individuals may find this mattress too firm, but the Softer WinkBed (4) or Luxury Firm WinkBed (6) may be more suitable.
Construction Breakdown
The Firmer WinkBed features adaptive polyfoam quilted into the cover, followed by a second foam layer. Despite the firm feel, our testers noticed a plush surface after getting onto the mattress and deeper cushioning as their bodies settled into the comfort system. The second layer is infused with cooling gel intended to dissipate body heat.
In the support core, thicker coils rest beneath your torso and hips – two areas where people tend to carry a disproportionate amount of weight. Most of our testers sank very little, if at all. This was especially true for the side and back sleepers on our team. The coils are also reinforced along the perimeter to protect the edges from sinkage. A cover made of eucalyptus-derived Tencel fabric encases the mattress. We noticed that this naturally breathable material made the surface feel cool to the touch.
Trial, Shipping, and Warranty
Each Firmer WinkBed comes with a 120-night trial period. If you find this mattress feels too soft or too firm, you can exchange it for a WinkBed with a different firmness level at no extra cost. The replacement model comes with a 60-night trial. You’ll also receive a lifetime warranty against structural defects for the WinkBed you decide to keep.

Helix Twilight
A firm hybrid with gentle cushioning and strong coil support.
Key Details
- Who it’s best for: Side sleepers who weigh more than 230 pounds and back sleepers up to 230 pounds.
- Feel: Minimal contouring with a strong bounce across the surface.
- What it’s made of: Memory foam comfort layer and transitional polyfoam over a pocketed coil support core.
- What we don’t like: Side sleepers weighing up to 230 pounds will probably need a softer mattress.
Scoring & Reviews
The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
As a firmer model in the base Helix lineup, the Helix Twilight predictably didn’t test quite as well as their other models, but that doesn’t mean it tested poorly. It’s foam comfort layers are still fairly thick, and our testers noticed only a little movement across the bed.
Pressure Relief
All of the Helix base models have somewhat thick foam comfort layers and conform fairly close to the body. Consequently, they’ve all performed fairly well in our pressure mapping tests, with notably less pressure in the hips and shoulders than many hybrids. The Twilight in particular relieves pressure a little worse than other Helix beds, as it’s a firmer model.
Temperature Control
The Helix mattresses perform about average for hybrids when it comes to sleeping cool. Memory foam is well-known for its tendency to sleep hot, as it often traps and retains heat through the night, but the coil cores of these beds promote airflow to help balance out heat retention.
Edge Support
All Helix mattresses feature a reinforced perimeter, meaning the coils on the edges are thicker than the coils in the middle of the bed. When putting this to the test, we found significantly less sinkage on the edge than the middle while applying weight. As a firmer model in the Helix lineup, the Twilight provides better edge support than other Helix beds.
Ease of Movement
Helix mattresses tend to be fairly responsive and bouncy, and all tested well for ease of movement. The Twilight in particular tested very well, as the firmer layers prevent sinkage and make for effortless movement.
Durability
Overall, we anticipate that all of these Helix mattresses will hold up well over the years. While some boast average durability features — the Plus and Sunset, for instance, which have slightly softer designs — others may last up to nine, like the Twilight and the Dawn. In our research, we found that firmer Helix models would probably last longer with layers of coils preventing sinkage over the years.
Full Breakdown
If you’re a side sleeper, most firm mattresses won’t provide enough cushioning or contouring for you to sleep comfortably. The Helix Twilight is a notable exception. The mattress contains two foam layers that adapt to the body, resulting in even weight distribution to alleviate pressure buildup in the shoulders and hips – a common issue among the side sleepers on our team.
How It Performed
Among our testing team, the side sleepers who felt most comfortable on the Twilight weighed at least 130 pounds. The mattress was also popular among our back sleepers of 130 pounds or more and stomach sleepers between 130 and 230 pounds. None of our testers struggled when moving across the Twilight’s surface, which we attributed to its strong coil system.
We’ve found that the Twilight sleeps quite cool. This is due to steady air circulation through the coil layer and a breathable knit cover to help the surface maintain a comfortable temperature. Our testers noticed minimal heat buildup on the surface when evaluating the mattress for temperature control. The Twilight’s firm, responsive feel also ensured strong performance during our ease of movement and edge support tests.
Construction Breakdown
A memory foam comfort layer and polyfoam transitional layer make up the Twilight’s comfort system. While the mattress has a firm (7) feel, our testers noticed moderate yet even conforming from the Twilight’s foam layers. The support core contains pocketed coils with extra perimeter support. As a result, we felt strong pushback when lying near and sitting along the edges of the mattress.
If you’d like to upgrade, the Helix Twilight Luxe contains all of these elements as well as a pillow-top surface with additional foam padding. The side sleepers on our team weighing up to 230 pounds appreciated the plusher feel of this mattress. Twilight Luxe models also feature zoned support cores with thicker coils to reinforce the chest, stomach, and hips.
Trial, Shipping, and Warranty
Helix offers free shipping to all 50 states. Twilight mattress purchases come with a 120-night sleep trial, and a lifetime warranty protects against structural defects.

Saatva Classic – Firm
Traditional innerspring with a plush euro-top and excellent breathability.
Key Details
- Who it’s best for: Back and stomach sleepers weighing at least 130 pounds.
- Feel: The surface is exceptionally springy, but you’ll notice some extra cushioning below your lower back.
- What it’s made of: Polyfoam and a memory foam lumbar pad encased in a Euro-top cover, followed by pocketed microcoils and steel innerspring coils in the support system.
- What we don’t like: Bouncy design may result in motion transfer for couples.

Durability
The Saatva Classic is stacked with features that help ensure durability. It’s constructed with both pocketed and support coils, plus polyfoam and memory foam comfort layers for additional comfort and support. Shoppers have a choice of thickness and firmness levels, and in general, going with thicker and firmer options can help add to the longevity. With its thick, 13-gauge coils in the bottom layer providing a sturdy base, this mattress should easily make it to the 10-year mark.
Full Breakdown
The Saatva Classic is another luxury hybrid we’ve tested that’s available in multiple firmness levels. If you’re looking for sturdy support and a fair amount of responsiveness, we recommend the firm (8) feel. This mattress contains two coil layers. As a result, our testers noticed generous pushback and exceptional stability along the perimeter.
How It Performed
We found during our tests that the Saatva Classic’s dual-coil construction allowed the mattress to perform better than traditional hybrids in several key categories. Temperature control was one standout area. Both coil layers circulate air, and the cover is made of breathable organic cotton, so we didn’t detect much heat buildup on the surface. Our testers also noticed minimal sinkage along the edges, and none of us felt trapped when moving across the surface.
Our tests showed the firm Saatva Classic should be most comfortable for side sleepers weighing more than 230 pounds and back and stomach sleepers weighing at least 130 pounds. If you are lighter than these groups, the soft (3) or medium firm (6) versions of this mattress may be more suitable.
Construction Breakdown
The Saatva Classic begins with a Euro-top surface containing foam and fiber padding to prevent the surface from feeling too stiff. A memory foam strip beneath your lower back can also promote even alignment and reduce pressure in the lumbar region and hips. The first coil layer consists of pocketed minicoils for transitional support, followed by a support core of low-gauge hourglass coils made from recycled steel.
You can choose between two profiles for your Saatva Classic. The 11.5-inch model contains 4-inch hourglass coils, while the 14.5-inch model contains 7-inch hourglass coils. If you’re seeking extra reinforcement, we recommend the latter – although both versions of the mattress proved highly supportive during various stages of our hands-on mattress tests.
Trial, Shipping, and Warranty
After you’ve placed your order, Saatva works with you to coordinate free White Glove delivery that includes setup of the Saatva and removal of your existing mattress. You then have 365 nights to try it out with the option to return it for a refund, minus $99 deducted for return pickup. The mattress comes with a lifetime warranty to cover potential defects.

Plank Firm
A reversible foam mattress with an ultra-supportive feel on both sides.
Key Details
- Who it’s best for: Back and stomach sleepers who weigh more than 230 pounds.
- Feel: The firm side offers light contouring, while the extra firm side barely conforms at all.
- What it’s made of: Each comfort system contains comfort layers of polyfoam, and they share a high-density foam support core.
- What we don’t like: Lacks the cushioning needed for most side sleepers and people under 130 pounds.
Scoring & Reviews
The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
Both sides of the Plank Firm Mattress use firm foams that absorb less motion than softer foams. This means that some vibrations may be felt across the surface of the bed. However, the foam isn’t bouncy on either side, so these vibrations are not pronounced.In our testing, it was rare for sleepers to be awoken by the movement of a bed partner. However, people who sleep very lightly may be better off with a mattress that offers more contouring and motion isolation.
Pressure Relief
The Plank Firm is crafted to provide a stable, even plane. As a result, it offers minimal pressure point relief, especially for side sleepers. The firm (7) side offers a bit more cushioning and relief than the extra firm side (9).While it lacks deep contouring and pressure relief, the sturdy mattress surface can provide effective support to many sleepers over 230 pounds and to people who sleep on their back or stomach.
Temperature Control
The Plank Firm’s sink-resistant surface and optional cooling top panel promote a cooler night’s sleep compared to other foam models. Because of the firm design, sleepers do not sink deeply into this bed. Steady airflow around the body can help dissipate heat.While both sides sleep relatively cool, the extra firm side has the edge since it traps virtually no heat around the skin. For either model, the optional cooling panel is designed to further enhance temperature regulation.
Edge Support
Because it is designed to have very little give, the Plank Firm maintains much more edge support than most all-foam mattresses. The edges of the extra firm (9) side are especially sturdy, allowing you to easily sit or sleep near the perimeter of the mattress.
Ease of Movement
Our testing team found virtually no risk of feeling “trapped in the bed” when sleeping on either side of the Plank Firm Mattress. There was very little resistance when turning over or switching sleeping positions. This stands in stark contrast to many all-foam mattresses that hug the body and restrict movement.
Durability
Foam mattresses are generally the least durable type, but the Plank Firm’s use of high-density polyfoam should help it perform longer than average. All types of foam wear down over time, resulting in permanent body impressions and sagging. That being said, memory foam and low-density foam wear out fastest, so the very dense Plank Firm should resist deterioration for at least six to seven years.
Full Breakdown
Most of the flippable mattresses our team has tested feature at least one surface that falls between soft and medium. The Plank Firm is a solid choice for anyone who prefers to sleep on a firm mattress most nights. One side is firm (7), and the other is extra firm (9), the latter of which is among the firmest surfaces we’ve tested firsthand.
How It Performed
As a firmer-than-average mattress, the Plank Firm performed well in areas where other all-foam beds we’ve tested have fallen short. The edges felt highly stable to us, particularly on the extra firm side, and our testers could move across both surfaces with minimal sinkage. Above-average cooling was another quality we noticed throughout our tests. Even without the phase change panels, our temperature sensors detected very little heat buildup.
The majority of our testers preferred the Plank Firm’s firm side. In particular, our back sleepers over 230 pounds and stomach sleepers weighing at least 130 pounds felt comfortable and sufficiently supported on this surface. The stomach sleepers on our team weighing more than 230 pounds also enjoyed the extra firm side, but other testers found this surface too firm.
Construction Breakdown
The Plank Firm’s firm side contains a top layer of soft fibers quilted into the cover, followed by a layer of TitanFlex polyfoam. We consider the TitanFlex a “best of both worlds” material that combines the traditional foam’s cushioning and latex’s responsiveness. Our testers noticed considerable bounciness when moving across this side of the mattress. The extra firm side does not feature any TitanFlex. We felt little to no contouring on this surface.
A support core of high-density polyfoam is located between the comfort systems. Our testers found that this layer provides excellent stability for each side. If you are a hot sleeper, we recommend adding a phase change panel to both sides of the mattress. This panel is sewn into the cover and intended to capture and remove body heat. While none of our testers felt excessively warm on either of the Plank Firm’s surfaces, we noticed a substantial difference in cooling and heat dissipation.
Trial, Shipping, and Warranty
Brooklyn Bedding backs the mattress with a 120-night sleep trial. If you decide to keep the Plank Firm, you’ll also receive a lifetime warranty.

Leesa Plus Hybrid Mattress
Sturdy design, temperature control, and moderate cushioning.
Key Details
- Who it’s best for: Side and back sleepers weighing at least 130 pounds.
- Feel: Medium firm (6) design with foam layers that gently contour to your body and a coil core that feels robust and supportive – especially along the perimeter.
- What it’s made Of: A Euro-top comfort system with three layers of adaptive polyfoam, followed by pocketed coils with a reinforced perimeter and high-density base foam.
- What we don’t like: People who weigh less than 130 pounds will probably need a softer mattress.
Scoring & Reviews
The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
We found that the Leesa Plus Hybrid offers average motion isolation for a hybrid mattress.The foam layers and pocketed coils work to reduce how much vibration ripples across the bed, but there’s a degree of bounciness that makes some motion transfer inevitable.Based on our testing, we don’t think this will pose an issue for most couples or co-sleepers, but it could be a drawback for people who are easily stirred from sleep by movement in their bed.
Pressure Relief
Our testing team gave high marks to the Leesa Plus Hybrid for its ability to relieve pressure and promote healthy spinal alignment.The top foam layers are most responsible for cushioning the body, adapting to the body’s weight and pressure. The bottom layers, including the coils, help create balance by resisting excess sinkage.
Temperature Control
The Leesa Plus Hybrid resists heat buildup well. The foams in the comfort system, including the gel-infused top layer, help minimize heat retention. The coils also provide space for ventilation to keep the mattress from getting too hot.People who are very hot sleepers may want a mattress with more elaborate cooling features, but our testing suggests that most people will have no issues staying at a comfortable temperature on the Leesa Plus Hybrid.
Edge Support
We found the Leesa Plus Hybrid offers impressive edge support, making it ideal for individuals who want to use the entire surface area of their mattress or who often sit on the edge of the bed.This perimeter support can be attributed to reinforced coils that run along the perimeter of the mattress. These coils, along with the denser support foams, help maintain a dependable edge without bothersome sagging.
Ease of Movement
Our testers found that the Leesa Plus Hybrid was average or slightly below average for ease of movement. Although the mattress doesn’t significantly impede movement, it doesn’t have the springiness that you find in many hybrid or innerspring mattresses.None of our combination sleepers felt that this was a serious problem, but it may be a consideration for people who want a mattress that feels like it gives you a little push when you adjust your body’s position.
Durability
The Leesa’s 4-inch comfort system and thick pocketed coil core combine to deliver ongoing support and pressure relief. Specifically, the coils are 13.5-gauge, which is one of the thickest you’ll find in the mattress industry. These components are designed to withstand a combined sleeper weight of over 1,000 pounds without prematurely wearing out. We expect this mattress to last a good 6.5 to 7.5 years, and you can extend the lifespan by regularly rotating it.
Full Breakdown
Firm hybrid mattresses don’t always excel at pressure relief, but the Leesa Plus is a notable exception. This medium firm (6) mattress features three foam layers over a bed of pocketed coils, creating a soothing balance of cushioning, bounce, and sturdy overall support. Our tests show the mattress is a particularly strong match for side and back sleepers who weigh 130 pounds or more, as well as couples, hot sleepers, and people who often lie close to the edge of their bed.
How It Performed
Since the Leesa Plus Hybrid has a well-rounded design, it fared well among different sleeper types on our testing team. The highest ratings came from side sleepers over 230 pounds and back sleepers between 130 and 230 pounds, but most people who use either position found the mattress comfortable and sufficiently supportive. The same held true for our stomach sleepers under 130 pounds.
Edge support is a key strength, and this can be attributed to the reinforced perimeter coils that push back against your weight and withstand compression well when you get in and out of bed. We were also impressed with how cool the Leesa Plus slept. All three foam layers have an open-cell composition, so they don’t retain as much heat as traditional memory foam, while the coils promote plenty of airflow to keep the interior at a comfortable temperature.
Construction Breakdown
The Leesa Plus Hybrid Mattress features a comfort system with three foam layers encased in a Euro-top cover. Cooling gel infused into the top foam layer is intended to dissipate heat from the surface. The third foam layer is denser than the other two, and should provide enough pushback to create a buffer between your body and the support core.
Pocketed coils and high-density base foam give the Plus Hybrid a secure and stable feel. Thicker coils line the perimeter to protect the edges from sinkage when you get on and off of the mattress. A breathable poly-viscose cover encases the inner layers. At 13 inches thick, the Plus is a high-profile model but shouldn’t require a deep-pocket fitted sheet.
Trial, Shipping, and Warranty
The Plus Hybrid’s sticker price is lower than average and shipping is free to all 50 states. Leesa’s sleep trial runs for 120 nights, during which you can test out the mattress in your own room and – after sleeping on it for at least 30 nights – return it for a refund. If you decide to keep the Plus, it’s further covered under a lifetime warranty.

The Silk & Snow Mattress is an all-foam model that comes in three firmness levels. If durability is a top concern, choose the firm option, but you should still only expect around six or seven years of mattress life. Each model has a polyfoam base layer with a gel memory foam layer above in the comfort level, but without coil support, it will sink in over time.

Silk & Snow has earned a reputation for high-quality sleep products at approachable sticker prices. The company’s flagship foam mattress nicely exemplifies this trend with a sturdy, three-layer design that provides a soothing balance of cushioning, bounce, and support. You can choose from two firmness levels for the mattress – we’re focusing on the firm (7) model because it is a better match for people who weigh more than 230 pounds, especially those who sleep on their backs and/or stomachs.
How It Performed
The firm Silk & Snow Mattress was a big hit among our testers who weigh at least 130 pounds. While the most favorable ratings came from side sleepers, back and stomach sleepers in this weight range found the mattress comfortable and sufficiently supportive. The versatile construction also makes this model a solid pick for combination sleepers who switch between different positions throughout the night.
Like other foam mattresses we’ve evaluated, the Silk & Snow performed well during our tests for pressure relief and motion isolation. The adaptive comfort layers form a mold around your figure without sinking or hugging too closely, which helps align your spine and reduce pressure buildup in areas like the shoulders and hips. We also noticed little to no movement transferring on the surface when two testers lied side by side on the mattress.
Construction Breakdown
The Silk & Snow Mattress contains a top comfort layer of dense memory foam, followed by transitional polyfoam. These materials contour to the body, but the firm design ensures minimal hugging and sinkage. A cooling gel infusion in the memory foam is also intended to stave off heat retention. The support core contains high-density polyfoam, and the cover – which is removable and machine-washable – is made of stretch-knit polyester.
Trial, Shipping, and Warranty
In addition to carrying a below-average sticker price, the Silk & Snow Mattress qualifies for free ground shipping throughout the contiguous U.S. and provincial Canada. Your order includes a lengthy 365-night sleep trial to give you ample time to sleep on the mattress in your own home. If you’re satisfied with your purchase, the mattress is also covered under a 15-year manufacturer’s warranty.

Durability
The Brooklyn Bedding Signature Hybrid has an estimated lifespan of six to seven years. As with other hybrids, the pocketed coils provide a solid base that evenly distributes pressure to prevent excessive strain on any one area. The most vulnerable part of the mattress is the comfort system, particularly the quilted top. The softer foams used in the mattress’ top layers may eventually develop imprints that affect the cushioning, something that’s more prominent in the softer model.
Full Breakdown
Brooklyn Bedding’s Signature Hybrid is available in three firmness levels. All three have performed well during our tests, but we’re singling out the Signature Hybrid – Firm for people who need extra support from their mattress. The firm (8) Signature features foam layers that lightly cushion the body, reducing pressure along the spine in the process, but thick coils with perimeter support help ensure you won’t sink too much.
How It Performed
Our team tested all three versions of the Signature Hybrid. The Firm model’s most favorable ratings came from our side sleepers over 230 pounds and back and stomach sleepers weighing at least 130 pounds. If your weight falls below these ranges, we recommend one of the softer Signature Hybrid designs.
This model performed well in testing areas such as ease of movement, edge support, and temperature control. We also found the firm Signature Hybrid absorbs movement well, making it a solid choice for couples who need a mattress that isolates motion and feels supportive.
Construction Breakdown
The Signature Hybrid – Firm’s comfort system contains a top layer of memory foam over denser transitional polyfoam. The former is infused with cooling gel intended to dissipate body heat and help you sleep cool. In the support core, you’ll find 8-inch pocketed coils and a high-density foam base. The coils are reinforced along the perimeter to help you feel secure lying close to the mattress’ edges and reduce sinkage when you get in and out of bed.
Standard Signature Hybrid – Firm models are encased in breathable cotton covers quilted with a thin layer of foam. If you sleep exceptionally hot or reside in a warm or humid place, you can upgrade to a GlacioTex phase change cover that feels cool to the touch at all times. Adding the GlacioTex cover increases the sticker price by up to $200.
The Signature Hybrid – Firm is available in 14 different sizes. In addition to standard mattress dimensions, your options include a split California king for couples who share adjustable beds, an Olympic queen for those who need extra width, and several RV-friendly sizes.
Trial, Shipping, and Warranty
An approachable sticker price and free shipping for orders in the contiguous U.S. make the Signature Hybrid – Firm a good option for shoppers with limited budgets. Brooklyn Bedding’s sleep trial runs for 120 nights, and the mattress is further backed by a lifetime warranty if you decide to keep it.

Helix Dawn
Very firm bed intended for stomach sleepers and heavy back sleepers.
Key Details
- Who it’s best for: Back and stomach sleepers over 230 pounds.
- Feel: Light contouring with robust coil support and strong bounce.
- What it’s made of: Polyfoam comfort layers, followed by a pocketed coil support core.
- What we don’t like: Side sleepers may not receive enough cushioning and couples are likely to notice motion transfer.

SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
As a firmer model in the base Helix lineup, the Helix Dawn predictably didn’t test quite as well as their other models, but that doesn’t mean it tested poorly. It’s foam comfort layers are still fairly thick, and our testers noticed only a little movement across the bed.
Pressure Relief
All of the Helix base models have somewhat thick foam comfort layers and conform fairly close to the body. Consequently, they’ve all performed fairly well in our pressure mapping tests, with notably less pressure in the hips and shoulders than many hybrids. The Dawn in particular relieves pressure a little worse than other Helix beds, as it’s a firmer model.
Temperature Control
The Helix mattresses perform about average for hybrids when it comes to sleeping cool. Memory foam is well-known for its tendency to sleep hot, as it often traps and retains heat through the night, but the coil cores of these beds promote airflow to help balance out heat retention. The Dawn sleeps a bit cooler than the other models thanks to the fact that is has less foam in the comfort layers.
Edge Support
All Helix mattresses feature a reinforced perimeter, meaning the coils on the edges are thicker than the coils in the middle of the bed. When putting this to the test, we found significantly less sinkage on the edge than the middle while applying weight. As a firmer model in the Helix lineup, the Dawn provides better support than other Helix beds.
Ease of Movement
Helix mattresses tend to be fairly responsive and bouncy, and all tested well for ease of movement. The Dawn in particular tested very well, as the firmer layers prevent sinkage and make for effortless movement.
Durability
Overall, we anticipate that all of these Helix mattresses will hold up well over the years. While some boast average durability features — the Plus and Sunset, for instance, which have slightly softer designs — others may last up to nine, like the Twilight and the Dawn. In our research, we found that firmer Helix models would probably last longer with layers of coils preventing sinkage over the years.
Full Breakdown
Helix Sleep’s product line includes an extensive selection of hybrid mattresses, each designed for certain people based on body type, sleep position, and firmness preferences. The Dawn is the firmest of the brand’s luxury hybrids, and our test team rated it as an 8 on our 10-point scale. The foam layers offer a bit of surface cushioning, while a coil system gives the bed a responsive feel couples may enjoy for sex.
How It Performed
Our testers found the Dawn offered excellent reinforcement and should appeal to anyone who wants a firm mattress. The firm feel was best suited to back and stomach sleepers on our team who weigh more than 230 pounds, but those between 130 and 230 pounds should also appreciate the even surface. The coils helped the mattress sleep cool by generating consistent airflow throughout the interior.
If the Dawn sounds appealing but you’re looking for something slightly softer, the Twilight Luxe (7), Dusk Luxe (6), and Midnight Luxe (6) are also reasonably firm. Meanwhile, the Dawn Luxe upgrade may be a good fit if you’re looking for firmness with a bit more surface cushioning. This model has a pillow-top and zoned interior coils for extra support and a firm (8) feel.
Construction Breakdown
The Dawn’s comfort system begins with a layer of polyfoam that slightly cushions the surface. Underneath is a polyfoam transitional layer that prevents your body from sinking into the coils. Our testers reported even contouring from head to toe and even support for your body, as well as some surface-level bounciness that made getting in and out of bed easier. The support core contains pocketed coils that reinforce the sleep surface with thicker low-gauge coils lining the perimeter to make the edges feel stable. A polyester cover encases the mattress, which measures 12 inches thick.
Trial, Shipping, and Warranty
Helix Sleep offers free ground delivery to all 50 states. Your Dawn purchase includes a 120-night sleep trial for testing the mattress and a lifetime warranty against structural defects if you choose to keep it.

Durability
The Bear Elite Hybrid Mattress scores above average for durability thanks to its pocketed coils, reinforced perimeter, and memory foam and polyfoam layers. The mattress comes in three firmness levels, and going firmer will typically extend the life of the mattress a bit more. Overall, you should expect around seven to eight years of use.
Full Breakdown
The Bear Elite Hybrid is available in three designs, the firmest of which we’ve placed as an 8 on our 10-point firmness scale. This version of the mattress caters to couples in several ways. Strong edge support allows you and your partner to use the entire mattress surface for sleep and sex, the sturdy coil system makes the surface responsive and easy to move across, and cooling components ensure excellent temperature regulation.
How It Performed
The firm Elite Hybrid’s most favorable ratings came from our side sleepers weighing more than 230 pounds, back sleepers weighing at least 130 pounds, and stomach sleepers between 130 and 230 pounds. Cushioning foam layers combined with a sturdy coil system made the mattress feel balanced and sufficiently supportive, particularly around the torso and hips, where people tend to carry more weight compared to other areas of the body.
We were also impressed by the Elite Hybrid’s temperature-regulating abilities. Our team attributes the mattress’ superior cooling to its breathable cover, copper-infused comfort layer, and coils that promote consistent airflow throughout the interior. None of our testers had a hard time moving across the mattress, and we noticed very little sinkage along the perimeter during our edge support tests.
Construction Breakdown
The Elite Hybrid’s comfort layer is composed of memory foam infused with copper, which has natural cooling and moisture-wicking properties. A polyfoam transitional layer provides additional cushioning while maintaining even support for your body. While the mattress feels firm and supportive, we noticed even contouring and weight distribution from the foam layers. The polyfoam is also divided into five firmness zones, so we didn’t experience any sinkage around the midsection.
The support core consists of pocketed coils over a base layer of high-density foam. Strong pushback from the coils reinforces the zoned transitional foam, and all of our testers could lie comfortably on the mattress – even those weighing more than 230 pounds. A cover made from a Celliant-blend fabric encases the Elite Hybrid. Celliant is a textile engineered for exceptional breathability and heat dissipation. As a result, we felt minimal heat buildup when testing the mattress for temperature control.
Seven sizes are available, including a split king size for adjustable beds.
Trial, Shipping, and Warranty
Bear offers free shipping to customers in the contiguous U.S. and a 120-night sleep trial. Customers can return mattresses anytime after the 30-night break-in period. Elite Hybrid purchases come with a lifetime warranty that protects against structural defects.

Titan Plus Core
A firm hybrid that provides excellent support for heavier people.
Key Details
- Who it’s best for: Side and back sleepers over 230 pounds who are shopping on a budget.
- Feel: The mattress is quite firm, but the top layer conforms to a noticeable extent. Coils deliver strong pushback.
- What it’s made of: A thin memory foam comfort layer, transitional polyfoam, and a pocketed coil support core.
- What we don’t like: People who weigh less than 230 pounds will probably find it too firm.
Scoring & Reviews
The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
SELECT AN ICON TO VIEW DETAILS:
Motion Isolation
Beds with good motion isolation help keep movement on one side of the bed from disturbing the sleeper on the opposite side. Our team found that the Titan Plus Core had very good motion isolation due to the pocketed coil design.Traditional coil beds generally have poor motion isolation. The Titan Plus Core’s pocketed coils, which are wrapped in fabric, can be compressed individually without affecting the surrounding coils. This results in good motion isolation on the surface.
Pressure Relief
In our tests, the Titan Plus Core offered good pressure relief for most sleepers, and particularly for heavier people. However, lighter sleepers will likely find that the mattress feels too firm. Remember that this is a firm bed, with a relatively thin comfort layer. This means that conforming is minimal, and the mattress material doesn’t “hug” the body. For those used to an all-foam mattress, the Titan Plus can feel a lot different in terms of pressure relief.
Temperature Control
The Titan Plus Core performed very well during temperature control tests. Its coils promote airflow, helping the bed stay cool. Gel-infused memory foam in the top comfort layer also helps to draw heat away from the body.We found that the base model of the Titan Plus did a good job of maintaining a comfortable sleeping temperature. For those who tend to sleep hot, the optional cooling cover may be a worthwhile addition.
Edge Support
Edge support is a measure of how supportive a mattress feels around its outer perimeter. This is an important factor for those who like to sit at the edge of the mattress, as well as for people who have difficulty getting in and out of bed.The Titan Plus Core has excellent edge support overall. Its thick coil system, combined with firm foam layers, means it provides edge support that is significantly better than average.
Ease of Movement
In our tests, the Titan Plus Core had very good ease of movement. This is due to the bed’s firm design and minimal “sinkage”. Unlike softer all-foam mattresses, sleepers won’t sink into the bed. This makes it significantly easier to change positions and get in and out of bed.
Durability
The Titan Plus Core is one of the firmest and more supportive mattresses on the market. Not surprisingly, this design is also quite durable and resistant to wear and tear over time. Dense foam layers in the comfort system contour lightly, so they shouldn’t develop impressions or indentations too quickly, and the coils are robust for long-lasting stability. Expect a lifespan of at leat 8 to 9 years, which is longer than average for a foam hybrid.
Full Breakdown
If you weigh more than 230 pounds, you may need an exceptionally firm mattress to minimize sinkage around the midsection. The Titan Plus Core from Brooklyn Bedding registers as an 8 on our 10-point firmness scale, ensuring above-average reinforcement compared to other hybrid models. The top two layers provide gentle cushioning, but a sturdy support system stabilizes the mattress to keep your body aloft.
How It Performed
During our hands-on tests, the Titan Plus Core earned favorable ratings from our side, back, and stomach sleepers weighing more than 230 pounds. These testers were impressed with the stable feel and strong edge support, as well as how easily they could move across the surface. Back and stomach sleepers between 130 and 230 pounds also felt reasonably comfortable.
Our tests show cooling is a major strength of the Titan Plus Core. The GlacioTex cover is highly effective at dissipating heat — but even with the standard cover, the Titan Plus Core’s coils generate enough airflow to keep our testers comfortable. Given the bouncy feel, we also awarded the mattress high ratings for sex.
Construction Breakdown
The Titan Plus Core begins with a memory foam comfort layer, followed by transitional polyfoam. These layers contour to a minimal degree but still distribute your weight evenly to reduce pressure in the shoulders, lower back, and hips. The support core consists of pocketed coils over dense base foam.
Standard Titan Plus Core models are encased in soft cotton-microfiber covers. For an additional fee, you can upgrade to a GlacioTex Cooling Cover composed of phase change material that captures and releases body heat to maintain a comfortable surface temperature.
Trial, Shipping, and Warranty
The Titan Plus Core is available in seven sizes, including a split California king for couples who use an adjustable bed. Below-average pricing for a hybrid and free shipping anywhere in the contiguous U.S. make this mattress a solid choice for budget-conscious shoppers. You’ll also receive a 120-night trial period with your purchase and a lifetime warranty if you decide to keep the Titan Plus Core.

Why You Should (or Should Not) Sleep on a Firm Mattress?
We’ve found that firm mattresses work best for people over 230 pounds as well as back and stomach sleepers over 130 pounds. The added stability of a firm mattress helps prevent these groups from sinking too deeply into the surface, thereby promoting better alignment during sleep.
“Spinal alignment is crucial for both sleep quality and reducing the likelihood of waking up with aches and pains,” according to Dr. Nilong Vyas, “because it ensures that the spine retains its natural curvature while you sleep. When the spine is properly aligned, it allows for optimal support of the body’s weight, promoting relaxation and reducing stress on muscles and ligaments. This alignment helps prevent discomfort and stiffness at night, leading to deeper, more restorative sleep. Conversely, poor spinal alignment can lead to strain and tension, contributing to disturbances during sleep and the development of aches and pains upon waking. Maintaining good spinal alignment can significantly enhance overall well-being and comfort.”
Additionally, a firmer mattress that doesn’t contour deeply tends to retain little heat – a crucial feature for those who tend to sleep hot. The rigidity of a firm mattress also makes it easier to move across its surface. Whether you’re switching sleeping positions or simply getting out of bed, moving requires less effort on a sturdy surface. This can make a firm mattress well-suited to people who struggle with mobility.
However, it’s essential to remember that comfort is a personal experience. While back and stomach sleepers might favor firm mattresses, side sleepers and those with specific pressure points might find them uncomfortable.
The reduced sinkage in firm mattresses allows for better air circulation around the body, which can significantly improve temperature regulation during sleep.
How To Choose the Best Firm Mattress for Your Needs
Selecting a mattress goes beyond just pinpointing the right level of firmness. It’s a blend of understanding your body’s unique needs and recognizing what a specific mattress can potentially do for your sleep. To make the process easier, we tested hundreds of firm mattresses and gathered qualitative and quantitative insights that can make your decision easier.
Factors like price, contouring and cushioning, sleeping position, body weight, and materials all play a huge role. We’ll guide you through these considerations to help you find the right firm mattress for you.
Choosing the Right Firmness for You
The right firmness level is the one on which you feel most comfortable and wake up without any discomfort or pressure points. We employ a 10-point firmness scale to rate individual mattresses, but remember, everyone’s perception of firmness can differ. On our scale, anything from 6 to 10 is generally classified as firm, though a bed with a rating of 10 is quite rare and would probably feel uncomfortable to most sleepers
Sleeping Position and Body Weight
Your body weight and sleeping position significantly influence the ideal mattress firmness for your body. For back and stomach sleepers, firm mattresses can be a solid choice, since they offer the right blend of cushion and support. On the other hand, side sleepers usually benefit from a touch more softness.
“Maintaining proper spinal alignment can be challenging for stomach sleepers; however, a firm mattress can provide the necessary support to help achieve this,” says Dr. Vyas. “A firm mattress helps to keep the spine in a neutral position, reducing the risk of strain on the neck and back. Additionally, using a thin pillow or no pillow at all can further prevent unnatural spine bending. By prioritizing spinal alignment, stomach sleepers can improve their sleep quality and minimize the chances of waking up with aches and pains.”
Body weight affects how much your body sinks into a mattress’ surface. We’ve found that firm mattresses are often a great fit for people who weigh more than 130 pounds. For these sleepers, a firm mattress offers a balanced feel—some contouring paired with firmer support. People under 130 pounds are typically more comfortable on a softer surface that provides more contouring.
| Weight | Side Sleepers | Back Sleepers | Stomach Sleepers |
|---|---|---|---|
| Less than 130 lbs. | Soft (3) to Medium (5) | Soft (3) to Medium (5) | Medium Soft (4) to Medium Firm (6) |
| 130 to 230 lbs. | Medium Soft (4) to Medium (5) | Medium (5) to Firm (7) | Medium (5) to Firm (7) |
| More than 230 lbs. | Medium Firm (6) to Firm (7) | Firm (7, 8) to Extra Firm (9) | Firm (7, 8) to Extra Firm (9) |
If you have chronic pain in your back, hips, or shoulders, it’s important to understand how a mattress’s firmness level could affect your symptoms. “When considering mattress firmness for chronic pain, it’s important to recognize that individual needs vary,” says Dr. Cotliar. “While some people find relief with a firm mattress, others may require more cushioning. The key is finding a balance that supports proper alignment while alleviating pressure on sensitive areas.”
Contouring and Pressure Relief
A mattress should contour gently to your body, shaping itself around your natural curves. Adequate contouring improves pressure relief because it helps the mattress to evenly disperse body weight and avoid the buildup of pressure under common pain points like hips and shoulders.
Firm mattresses can offer excellent contouring and pressure relief even though they perform differently than softer mattresses. A firm mattress provides support by maintaining a consistent surface that props your body up, rather than allowing it to sink deeply. The cushioning on a firm mattress might be less pronounced than on a soft mattress, but it should still align with your body shape.
Back and stomach sleepers generally benefit the most from the level of contouring and pressure relief offered by a firm mattress, as these positions need consistent support to prevent the spine from arching unnaturally or the abdomen from sinking too deeply. On the flip side, side sleepers sometimes prefer a bit more give in their mattress to cushion their shoulders and hips.
Mattress Type and Quality
Although we’ve tested firm mattresses of virtually every type of construction, innerspring and hybrid models are usually the firmest. Innersprings provide a solid, consistent surface due to their coil construction, while hybrids have a top layer of latex or dense foam to balance support with gentle contouring. That said, you can find firm mattresses made from every material. Below are the qualities of each mattress type and how they contribute to firmness.
| Innerspring | Hybrid | Latex | Foam |
|---|---|---|---|
| Innersprings have a flat surface with a bit of bounce, contributed by their coil construction. Firmness within a given mattress depends on the density of these coils. Because innerspring mattresses tend not to have a plushy surface, they often feel firmer than other types. | Hybrids combine the steady coils of innersprings with foam or latex tops for more variable levels of cushioning. In addition to a bed’s firmness rating, check out the material and thickness of its top layer to gauge if it’s firm enough for you. Polyfoam has less sinkage than memory foam, and latex generally contours with minimal sink. | Latex variants, either natural or synthetic, balance responsiveness with firmness. Latex molds gently to the body without too much sinkage, and firmness tends to increase with the density of the latex used. | Foam is known for its plush, cushiony qualities, but it can also be formulated to have a firm feel. Look for a mattress that’s made from polyfoam instead of one with a thick memory foam layer. Memory foam contours closely to the body, but polyfoam — especially polyfoam with a higher density — has a firmer, more stable feel. |
The choice of mattress type not only impacts firmness and performance, but also its lifespan. Generally, high-quality latex and hybrid mattresses excel in durability, while foam can vary based on its density and composition.
Trials, Returns, and Warranties
A company’s trial period, return policy, and warranty offer protection in case the mattress you selected doesn’t align with your expectations.
A sleep trial allows you to experience the bed in the comfort of your own home and is especially crucial when you’re considering the firmness of the mattress. If the mattress doesn’t meet your expectations during the trial, many brands provide an option to exchange or return it.
Warranties, on the other hand, give assurance of the mattress’s durability and quality over time. Should there be any manufacturing defects or premature wear, the warranty acts as a promise from the company to address these issues, ensuring you receive the value for your investment.
How We Test: Rigor, Data, and Sleeper Feedback
Our industry-leading product testing team cares deeply about improving your sleep. Having a holistic understanding of a mattress’s role as part of a sleep system is paramount to our testing process. Since a bed’s comfort and feel depend largely on body weight and sleeping position, our testing team represents a wide range of body types, sleep positions, and comfort preferences.
In our Seattle-based Test Lab, we use an objective, hands-on process to evaluate mattresses across performance categories. The following are the key guidelines that inform our performance ratings. Our ultimate goal is to ensure you have all the information you need to make the best purchase decision for you.
Construction analysis: Our rating system is grounded in construction. Each mattress rating is derived at the intersection of quality, value, and versatility across a range of sleepers. We look at the bed’s price point, materials, firmness options, comfort and support systems, cooling technology, as well as brand reputation, and then we perform a detailed analysis that measures performance across six different categories to arrive at an overall score.
Quantitative product testing: During these hands-on lab tests, our team uses various tools and technology to evaluate a bed’s performance against motion isolation, pressure relief, temperature control, ease of movement, edge support, and potential for odor emissions. We use the outcomes from these tests to calculate a score for each category.
Field testing: Our field testers sleep on mattresses and other sleep products, like pillows, sheets, and mattress toppers, in their own bedrooms. After weeks of at-home testing, each field tester provides a detailed analysis of how the mattress performs, including what they like and dislike about the bed. We sought feedback from testers across all sleep positions and weight groups, but we focused especially on testers who sleep on their stomach or weigh more than 230 pounds since these sleepers tend to prefer firmer beds.
User feedback: Observations from mattress owners and users outside our team are invaluable to our research. We draw insight from surveys, sleep stories, and customer reviews to extract themes, fine-tune our ratings, and better understand how each product performs over time in a real-world setting.
How We Determine Our Overall Scores
To determine a mattress’s overall score, we assign weighted percentages to performance categories based on how important they are to the individual sleep experience. For instance, areas like pressure relief and temperature control tend to matter more to people than something like off-gassing, and because more people sleep on their side and back than on their stomach, we weigh those positions more heavily.
Performance Categories
Motion Isolation
This criteria alludes to the amount of motion a mattress absorbs when a sleeper moves on the surface. We use two testers lying side by side to evaluate motion isolation, who each feel for transfer while the other person moves on the mattress.
Temperature Control
To determine how well a mattress regulates temperature, we perform temperature tests and look closely at its materials and construction. Many mattresses are designed with cooling components meant to reduce heat retention.
Pressure Relief
A bed with strong pressure relief excels at preventing pressure from building up in areas like the shoulders and hips. Beds with even contouring and weight distribution are top performers when it comes to pressure relief.
Off-Gassing
A mattress in a box may release unpleasant chemical odors for a short period after you’ve unboxed it. The initial smell may be strong but typically fades within 2 or 3 days.
Ease of Movement
This criteria reflects how easily a sleeper can move across a bed’s surface. Responsive surfaces made of latex typically perform better than foam surfaces, which can inhibit movement.
Edge Support
We perform sit tests along a bed’s perimeter to measure how well the edges push back against weight. Mattresses with strong edge support have minimal sagging when sleepers sit on or lie close to the perimeter.

Frequently Asked Questions
Is a firm mattress better for back pain?
A firm mattress can help with back pain by promoting healthy sleep posture and neutral spinal alignment. However, the best mattress for back pain depends on the location and nature of the back pain as well as your preferred sleeping position.
“It’s important to note that ‘firm’ doesn’t necessarily mean ‘hard’,” says Dr. Cotliar. “The ideal mattress should provide support while still allowing for some give to accommodate the body’s natural curves.”
Is a firm mattress good for side sleepers?
A firm mattress may be a good choice for side sleepers over 230 pounds who can sink enough into the bed’s surface. A firm mattress may not be ideal for side sleepers under 230 pounds, as inadequate give can exert pressure on the shoulders and hips. A soft (3) to medium (5) mattress with more contouring provides better cushioning for lighter side sleepers.
Do firm mattresses last longer than soft mattresses?
While firmness can influence durability, we’ve found that its lifespan is more about the mattress’s construction, materials, and usage. Latex, high-density polyfoam, and hybrid mattresses often last longer than traditional innerspring and beds with lower-density foam that tend to degrade faster.
How can you make a mattress firmer?
Buying a mattress with the right level of firmness is the best way to ensure a consistent feel, but there are several ways to make a mattress firmer. A firm mattress topper can change the surface of the mattress, but won’t make up for sagging that happens over time in softer models. Rotating the mattress regularly may help with sagging due to a mattress’s age.
What is the best mattress firmness for couples?
Couples may have a tough time choosing a mattress if they have different firmness preferences. Some couples solve this by choosing a firmness level that’s between the two, with medium-firm (6) being a common choice for couples where one partner likes a firm mattress and the other likes a softer sleep surface. Others go for a split mattress, which allows for a different firmness level on each side.
Is a hard mattress good for posture?
A firm mattress can support healthy sleep posture by keeping the spine on an even plane. However, it’s crucial that the mattress isn’t excessively hard, as it should adapt to the body’s curves for optimal support. This means finding a firmness level that works for an individual’s weight and sleeping position.
“It is important to try out several mattresses and find the optimal one that provides the most support and comfort since one-third of our lives are spent sleeping,” says Dr. Vyas.
