How We Test
How We Determine Our Best Overall Score
With each mattress we test, our team follows the same comprehensive research and evaluation methodology to ensure objective, data-based findings. The mattress testing process consists of four stages, beginning with our detailed analysis of the bed’s construction, materials, and firmness. This cursory exam allows us to calculate an expected lifespan to determine our durability score. We also review the brand’s shipping and return policies, as well as its overall reputation for customer service and satisfaction.
The second stage involves hands-on evaluations in our Seattle Test Lab. We use a wide range of tools and technology to determine how well the mattress relieves pressure, isolates motion, regulates temperature, and resists deep compression when weight is applied. Once we’ve finished the lab-based stage, our field testers take the mattresses home and sleep on them in their own bedrooms for 2 to 3 weeks. These in-home experiences capture how the mattress performs night to night in an authentic sleep environment. Lastly, we collect and read verified customer reviews of each product to make sure our findings are in line with the general public.
Throughout this four-step testing process, we record data and notes that contribute to each bed’s overall and individual performance ratings. The graph below shows how every performance metric contributes to product scores.
How We Determine the Best Online Mattress for Side Sleepers
Over the last decade, we’ve brought more than 2,000 mattresses into our Seattle Test Lab. To evaluate each bed, we collect objective measurements and subjective feedback from our team of sleepers. This team represents different body weights, sleep positions, and comfort preferences to ensure our testing results are inclusive of all sleepers.
To select the best online mattresses for side sleepers, we went through our database and focused on models that stood out in several areas:
- Strong cushioning to relieve pressure around the hips and shoulders
- Sufficient support to help maintain spinal alignment
- High-quality materials that result in dependable overall performance
- Convenient online ordering and shipping directly to your home
Those criteria allowed us to generate a shortlist of top performers. From there, we debated the pros and cons of each option and selected our best overall mattress and other great options based on their specific strengths.

Best Overall
9.7/10Test Lab Score
Helix Midnight Luxe
A foam-on coil hybrid that excels at pressure relief, motion isolation, and sleeper support.
Key Details
- Who It’s Best For: Couples, hot sleepers, and people with lower back pain.
- Feel: Medium firm (6) with impressive cushioning around pressure points and limited sinkage beneath the midsection.
- What It’s Made Of: Gel-infused and high-density memory foam, polyfoam, and zoned pocketed coils with a reinforced perimeter.
- What We Don’t Like: The contouring foams can make movement on the mattress somewhat difficult, and the price increases significantly if you add the optional upgrades.
- Why It Won Best Overall: The Midnight Luxe checks nearly every box for side sleepers, providing ample cushioning for the hips and shoulders, dependable support, and strong all-around performance.
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.
Performance
Full Breakdown
The Helix Midnight Luxe is an online mattress that brings together many of the key elements that side sleepers need for great sleep. Foam comfort layers contour evenly to relieve pressure points, while a robust coil system prevents pronounced sinkage.
How It Performed
In our testing, the Midnight Luxe delivered strong results in almost every category. It isolated motion effectively, stayed cool, and felt sturdy around the perimeter.
Side sleepers of different body weights gave the mattress high ratings for pressure relief, and it also won over many back sleepers under 230 pounds and stomach sleepers under 130 pounds. That makes the Midnight Luxe an even more appealing option if you’re a combination sleeper or your sleep partner uses a different position.
What Makes the Helix Midnight Luxe Good for Side Sleepers
When you lie on your side, your shoulders and hips naturally dig into your mattress. The Midnight Luxe’s memory foam layers accommodate these joints for enhanced comfort. At the same time, the zoned underlying coils provide enough pushback to help keep the spine in a neutral position.
Construction Breakdown
The Midnight Luxe is 13.5 inches tall with a medium firm (6) feel.
The comfort system includes layers of gel-infused memory foam and high-density memory foam. These materials are supported by transitional polyfoam for extra pushback. The pocketed coils are zoned to provide extra pushback around your midsection and reinforced along the perimeter to stabilize the edges. A dense foam base layer stabilizes the coils.
A breathable Tencel cover comes standard with the Midnight Luxe. Helix offers a cover upgrade that includes GlacioTex fibers designed for additional cooling. Other upgrade options include a CoolForce layer for temperature neutrality and an ErgoAlign layer for firmer support beneath the midsection.
Trial, Shipping, and Warranty
The Midnight Luxe comes with a 365-night sleep trial. You are required to keep the mattress for 30 nights before initiating a return.
Shipping is free within the contiguous U.S., and delivery to Alaska, Hawaii, and Canada costs extra. If you need installation or old mattress removal, White Glove delivery is available in many locations for an additional charge. Helix also backs the Midnight Luxe with a lifetime warranty.
Best Value
8.8/10Test Lab Score
Brooklyn Bedding CopperFlex Memory Foam
An all-foam mattress that hugs and soothes pressure points for restful sleep.
Key Details
- Who It’s Best For: Side sleepers between 130 and 230 pounds, and value seekers.
- Feel: Medium firm (6) with close contouring that doesn’t feel overly soft thanks to the zoned support core.
- What It’s Made Of: Six foam layers, including copper-infused memory foam, responsive polyfoam, multi-zone transitional foam, and a dense base.
- What We Don’t Like: It sleeps warmer and feels less responsive to many hybrid models.
- Why It Won Best Value: The CopperFlex Memory Foam delivers high-level pressure relief and motion isolation at an accessible price-point. This allows side sleepers to get comfort and support without having to splurge on a new 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.
Performance
Full Breakdown
An expensive mattress isn’t a necessity for great sleep. As a side sleeper, you can get high-end cushioning from the Brooklyn Bedding CopperFlex Memory Foam Mattress without having to blow past your budget. This mattress uses six individual foam layers to redistribute pressure away from your hips and shoulders while supporting your body with a balanced medium firm (6) feel.
How It Performed
Pressure relief was the CopperFlex Memory Foam’s biggest strength in our testing. While it was supportive for side sleepers of all body weights, it earned the highest praise from testers between 130 and 230 pounds.
Our team also said that the mattress absorbed vibrations, reducing disruptions from movement on the other side of the bed. This makes the CopperFlex a good choice for couples.
The weakest performance categories for the CopperFlex Memory Foam were temperature regulation, edge support, and ease of movement, but these were roughly on par with other all-foam mattresses — especially models at this price-point.
What Makes the CopperFlex Memory Foam Good for Side Sleepers
The CopperFlex Memory Foam allows the hips and shoulders to settle gently into the foam layers, reducing pressure where side sleepers tend to feel it most. The lower layers keep you from sinking too deeply, helping your body rest in a more even plane.
Construction Breakdown
The CopperFlex Memory Foam is 12 inches tall and has a medium firm (6) feel.
A top layer of polyfoam is quilted into the cover. Below it are layers of copper-infused memory foam, adaptive polyfoam, transitional polyfoam, and zoned polyfoam. A block of high-density polyfoam forms the support core, giving the mattress stability and pushback.
Trial, Shipping, and Warranty
The CopperFlex Memory Foam comes with a 365-night sleep trial. There is a 30-night minimum before you can initiate a return. Shipping is free within the contiguous U.S. Charges apply for shipping to Alaska, Hawaii, and Canada. Brooklyn Bedding backs the mattress with a lifetime warranty.
Best Hybrid
9.0/10Test Lab Score
Leesa Sapira Chill Hybrid
A foam hybrid that cushions your body without trapping heat.
Key Details
- Who It’s Best For: Side sleepers across a wide range of body weights, and people who want the ability to choose from multiple firmness options.
- Feel: Medium (5), medium firm (6), or firm (7) designs, with each model offering a blend of adaptive cushioning from the foams and light bounce from the coils.
- What It’s Made Of: Memory foam, polyfoam, transitional, and an 8-inch support core of zoned pocketed coils.
- What We Don’t Like: Edge support is less dependable on the medium (5) model.
- Why It Won Best Hybrid: The Sapira Chill Hybrid makes effective use of both foam and coils, providing side sleepers with pressure relief while also providing springiness, airflow, and sturdy support.
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.
Performance
Full Breakdown
The Leesa Sapira Chill Hybrid is a solid match for most side sleepers. Multiple foam layers relieve pressure, and the thick pocketed coil system provides robust underlying support. With three firmness levels to choose from, it can deliver great results for side sleepers across different body weights.
How It Performed
During our tests, side sleepers consistently gave high ratings to the Sapira Chill. The ideal firmness level varied by body weight. Testers under 130 pounds tended to prefer the medium (5) model, side sleepers between 130 and 230 pounds liked the medium firm (6) feel the most, and those over 230 pounds appreciated the extra resistance to sinkage on the firm (7) model.
Our tests also showed consistent temperature regulation and ease of movement, contributing to a well-rounded performance that suits many sleepers.
What Makes the Sapira Chill Hybrid Good for Side Sleepers
The foam comfort system in the Sapira Chill Hybrid conforms to your hips and shoulders, which helps redistribute pressure instead of concentrating it in those areas. The zoned coils provide targeted pushback to help keep heavier areas of the body from sagging into the mattress.
Construction Breakdown
The Sapira Chill Hybrid is 14 inches tall and comes in medium (5), medium firm (6), and firm (7) models.
The smooth and stretchy polyester-blend cover incorporates cooling fibers to dissipate heat from the surface. Memory foam and adaptive polyfoam are layered together to form the comfort system.
A thin layer of transitional polyfoam sits above the pocketed coil support core. The coils are zoned to provide more pushback around the midsection and reinforced along the perimeter for sturdy edge support.
Trial, Shipping, and Warranty
The Sapira Chill Hybrid includes a 365-night sleep trial with a mandatory try-out period of 30 nights.
Shipping is free to all 50 U.S. states. White Glove delivery is available for an extra charge to most customers in the contiguous U.S. Your purchase is backed by a lifetime warranty.
Best Pressure Relief
8.7/10Test Lab Score
Nolah Evolution
A cloud-like experience with a plush Euro-top in multiple firmness options.
Key Details
- Who It’s Best For: Couples and people with sensitive pressure points.
- Feel: Medium (5), medium firm (6), or firm (8), with a depth of contouring that varies according to the firmness you choose.
- What It’s Made Of: Organic cotton, multiple layers of adaptive polyfoam, and an 8-inch pocketed coil support core.
- What We Don’t Like: The softest model provides less edge support and can limit movement on the mattress.
- Why It Won Best Pressure Relief: Our team was impressed with the Evolution’s ability to cushion pressure-prone areas. The multi-layer foam comfort system cradles your joints, while a zoned support system prevents excessive sinkage around the torso and hips.
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.
Performance
Full Breakdown
The Nolah Evolution is available in three firmness levels, letting each sleeper find the right fit for their body. With all three models, you get significant cushioning that helps decrease pressure buildup around your hips and shoulders.
How It Performed
During our hands-on tests, pressure relief was an undeniable strength of the Nolah Evolution Mattress. Side sleepers spoke highly of how the mattress accommodated their joints, and our pressure mapping tests confirmed that feedback.
We found that the medium (5) model was best suited to side sleepers under 130 pounds, the medium firm (6) worked especially well for people between 130 and 230 pounds, and the firm (8) option was most supportive for side sleepers over 230 pounds.
Strong motion isolation was another highlight of the Nolah Evolution, particularly in the medium (5) model. The firmer designs provided stronger perimeter support and easier movement.
What Makes the Nolah Evolution Good for Side Sleepers
Different foam layers play a role in relieving pressure when you lie down on the Evolution. When you sleep on your side, the foams cradle your hips and shoulders, and the zoned support system holds up your midsection so that it’s easier to stay in a neutral spinal posture.
Construction Breakdown
The Nolah Evolution is 14 inches tall and is available in medium (5), medium firm (6), and firm (8) designs.
Its cover is made with organic cotton that is breathable and soft. The comfort system includes adaptive polyfoam, gel-infused polyfoam, and Nolah’s copper-infused AirFoam. A zoned transitional layer provides stronger support beneath key areas like the hips and lumbar region.
An 8-inch pocketed coil layer forms the support core. This gives the mattress a touch of bounce, and reinforced perimeter coils make the edges feel firmer and more stable. Nolah offers an optional upgrade to a pillow-top that includes additional foam and GlacioTex fibers intended to improve temperature regulation.
Trial, Shipping, and Warranty
The sleep trial for the Nolah Evolution lasts for 365 nights. There is a mandatory 30-night try-out period before you can ask for a return. Standard shipping is free to all 50 states. If you live in the contiguous U.S., you also have the option to pay extra for in-home setup and old mattress removal. Nolah provides a lifetime warranty for the Evolution.
Best for Back Pain
9.0/10Test Lab Score
Bear Elite Hybrid
A close-conforming memory foam hybrid offering great pressure relief.
Key Details
- Who It’s Best For: Side sleepers with back pain and people who want firmness choices.
- Feel: Medium (5), medium firm (6), or firm (8) with a comfortable amount of cradling for major pressure points and the lower back.
- What It’s Made Of: Copper-infused memory foam, multiple polyfoams, pocketed coils that are zoned for targeted support, and a quilted cover woven with cooling Celliant fibers.
- What We Don’t Like: The softest version can impede movement, while the firmest model may not offer enough cushioning for side sleepers under 130 pounds.
- Why It Won Best for Back Pain: The Bear Elite Hybrid delivers deep cushioning around the hips and shoulders with zoned support beneath the midsection, helping side sleepers avoid both uncomfortable pressure buildup and excessive sinkage.
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.
Performance
Full Breakdown
In addition to cushioning for the shoulders and hips, side sleepers with back pain typically need robust support under their lower back. The Bear Elite Hybrid’s solid construction includes adaptive foams and zoned coils. The ability to choose from three firmness options also allows you to make sure you get the right mix of cushioning and pushback.
How It Performed
Side sleepers gave high marks to the Bear Elite Hybrid during our hands-on tests. The best firmness level for any given tester corresponded to body type — the higher a person’s weight, the more they benefited from a firmer feel.
The mattress also scored well for edge support, temperature regulation, and motion isolation. Performance varied by firmness, with softer models absorbing more motion and firmer models providing stronger edges and facilitating easier movement.
What Makes the Bear Elite Hybrid Good for Side Sleepers
The upper foam layers conform around the shoulders and hips to reduce pressure when lying on your side. Beneath those layers, zoned coils provide reinforcement around areas that need more support, including the lower back and midsection.
That combination is especially useful for side sleepers who want pressure relief without sacrificing the support they need for proper spinal alignment.
Construction Breakdown
The Bear Elite Hybrid is 14 inches tall and comes in medium (5), medium firm (6), and firm (8) versions.
It has a quilted cover that contains Celliant fabric engineered to regulate temperature by dissipating excess heat. The comfort system includes copper-infused memory foam along with adaptive and responsive polyfoams. Bear also offers an optional cooling upgrade that adds a phase change material near the top of the mattress.
Transitional polyfoam separates the comfort system from the support core, which features pocketed coils arranged into zones for targeted midsection support. Dense base foam acts as a shock absorber for the coil system to stabilize the mattress.
Trial, Shipping, and Warranty
With the Bear Elite Hybrid, you get 365 nights to try out the mattress. You are required to keep the mattress for 30 nights before requesting a return.
Shipping is free within the contiguous U.S. Delivery to Alaska and Hawaii is available for an additional charge. The mattress is covered under a lifetime manufacturer’s warranty.
Best for Couples
8.7/10Test Lab Score
Lull Luxe Hybrid
A balanced foam hybrid with light cushioning and responsive support.
Key Details
- Who It’s Best For: Side sleepers who share their bed with a partner or pet.
- Feel: Medium firm (6) with moderate contouring for a plush surface that doesn’t sink like quicksand.
- What It’s Made Of: Memory foam, gel-infused memory foam, transitional polyfoam, and pocketed coils encased in dense foam for perimeter reinforcement.
- What We Don’t Like: The mattress may lack adequate support for some side sleepers over 230 pounds.
- Why It Won Best for Couples: The Lull Luxe Hybrid’s comfort system does an excellent job of absorbing movement, helping to prevent motion from spreading across the mattress and disturbing you or your sleep partner.
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.
Performance
Full Breakdown
A solidly built mattress, the Lull Luxe Hybrid combines cradling foams with supportive polyfoam and pocketed coils. The top layers, including memory foam quilted in the cover, absorb vibrations and allow couples to share the mattress without disturbing each other when they move around or get in or out of bed.
How It Performed
Our Test Lab team gave the Luxe Hybrid strong ratings for motion isolation. Both our objective and subjective evaluations found that the foam layers muffled vibrations, making movement hard to detect on the other half of the mattress.
Side sleepers across all body weights noted sufficient support and pressure relief, but the mattress was most popular among those between 130 and 230 pounds. A few testers over 230 pounds felt that the mattress was too soft.
The Luxe Hybrid is also a solid fit for couples with diverging sleeping positions. We found that it delivered sturdy support for back sleepers up to 230 pounds and stomach sleepers under 130 pounds.
What Makes the Lull Luxe Hybrid Good for Side Sleepers
The Lull Luxe Hybrid’s foam layers conform around the hips and shoulders, adapting to your body to redistribute pressure across a larger area. This can help you avoid painful impact against the mattress while also accommodating your body, helping you settle into a comfortable posture.
Construction Breakdown
The Lull Luxe Hybrid is 13 inches tall and has a medium firm (6) feel.
Memory foam is quilted into the cover to provide cushioning and motion isolation on the surface. The next layer is made with gel-infused memory foam designed to reduce heat buildup. Transitional polyfoam adds pushback and reduces sinkage.
The support core contains pocketed coils encased in extra-dense foam for added stability along the perimeter.
Trial, Shipping, and Warranty
The Lull Luxe Hybrid comes with a 365-night sleep trial. There is no mandatory break-in period for the trial. Shipping is free to addresses in the contiguous U.S. Customers in Alaska and Hawaii pay an additional fee for delivery. Lull provides a lifetime warranty for the Luxe Hybrid.
Best Cooling
8.6/10Test Lab Score
DLX Premier Hybrid
Versatile hybrid with a handful of single and split firmness options.
Key Details
- Who It’s Best For: Hot sleepers and couples with different firmness preferences.
- Feel: Available in medium soft (4), medium (5), medium firm (6), and firm (8), with progressively less contouring as firmness increases.
- What It’s Made Of: Breathable viscose batting, adaptive polyfoam, and pocketed coils. You can swap out one of the polyfoam layers for a softer or firmer feel.
- What We Don’t Like: DLX’s return process involves more steps compared to other online mattress brands. Softer models can retain more heat and can be harder to move on.
- Why It Won Best Cooling: Multiple materials enable airflow and cooling. The choice of firmness options also helps you avoid excessive sinkage, which can contribute to heat retention.
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.
Performance
Full Breakdown
The DLX Premier Hybrid gives side sleepers more control over how their bed feels than most online mattresses. You can choose from four firmness levels and one layer is removable, allowing you to change out the foam for a softer or firmer layer and dial in the balance of contouring and support. You can also opt for split firmness, giving each side a different feel. This versatility helps you maximize comfort and pressure relief along with temperature control.
How It Performed
Our testing found that the DLX Premier Hybrid felt both comfortable and supportive to side sleepers, but there was a relationship between body weight and preferred firmness.
Side sleepers under 130 pounds generally favored the medium soft (4) or medium (5) designs, while those between 130 and 230 pounds preferred the medium (5) and medium firm (6). People over 230 pounds tended to get the best support from the firm (8).
Nearly all Premier Hybrid variations proved to be effective at cushioning the hips and shoulders. Firmer models provided better edge support and slept the coolest. Softer models retained a bit more warmth, but offered better motion isolation.
What Makes the DLX Premier Hybrid Good for Side Sleepers
With the DLX Premier Hybrid, you can choose a different firmness level for each side, allowing you to pick the feel that lets your hips and shoulders sink in just enough for pressure relief without causing the rest of your body to sag into the mattress. The 3-inch comfort layer can be swapped out, giving you another way to fine-tune the feel after purchase.
Construction Breakdown
The Premier Hybrid is available in 12- and 14-inch profiles. Under the soft cover is a layer of breathable viscose batting designed to reduce heat retention. Two adaptive foam layers provide light cradling and gentle pressure relief.
A 3-inch comfort layer plays a major role in determining the mattress’s firmness and contouring. The zippered design allows this layer to be swapped out for something softer or firmer without you needing to replace the entire mattress.
Transitional polyfoam sits above the support core, which contains pocketed coils and a dense foam base.
Trial, Shipping, and Warranty
DLX offers a 120-night sleep trial. You must keep the mattress for at least 30 nights, after which you can work with DLX on a comfort adjustment, and, if that doesn’t work, request a full refund. You are required to find an organization that accepts mattress donations in order to process your return.
The DLX Premier Hybrid ships for free to addresses within the contiguous U.S. A lifetime warranty covers your purchase.
What to Consider When Shopping for an Online Mattress for Side Sleepers
Side sleepers have specific needs when looking for a new mattress. The right mattress cushions the hips and shoulders while providing enough support to keep the body aligned and prevent sinkage.
While firmness is an essential consideration, other factors matter as well. Mattress type, your body weight, and material construction can all play a role in identifying the best mattress for you.
What Makes a Mattress Good for Side Sleepers?
Because the hips and shoulders press down into a mattress, side sleepers normally need more cushioning than back and stomach sleepers. An excessively firm surface can cause pain to build in your joints. However, a mattress that feels overly soft can let your hips and shoulders sink in too far and fall out of line with the rest of your body.
As a result, the best mattresses for side sleepers strike a balance between pressure relief and support. Adaptive comfort layers can help distribute weight around your hips and shoulders, while a strong support core keeps the rest of your body in a more even line.
Mattress Type
Mattress type influences how a bed responds to your body and its overall performance. Most of the best-performing online mattresses for side sleepers are all-foam or hybrid mattresses.
- Foam mattresses: All-foam models often excel at pressure relief and motion isolation because their comfort layers contour to and cushion the body. However, they may have weaker edge support and retain more heat.
- Hybrid mattresses: Hybrids combine foam or other comfort materials with a coil support core. Their performance can be more variable because of the various ways they can be designed. However, they typically offer solid cushioning and support with more bounce and edge support than all-foam mattresses.
Although not as widely available online, latex mattresses and airbeds may also be good options for some side sleepers.
- Latex mattresses: Latex has a bouncy feel and tends to sleep cool. It can provide solid, responsive support for side sleepers but may lack the necessary contouring and cushioning. In our Test Lab, latex mattresses usually work best for side sleepers over 230 pounds.
- Airbeds: Airbeds allow you to change the firmness as often as you wish by adjusting the amount of air in the support chambers. This is useful for optimizing your firmness level, but these mattresses can be expensive and don’t always have enough cushioning materials above the air chambers.
Sleeping Position and Body Weight
Your body weight affects how deeply you sink into a mattress. This impacts how much cushioning and support you receive and, in effect, your sleep posture.
Side sleepers under 130 pounds usually benefit from a softer mattress that allows their hips and shoulders to settle into the comfort layers. Those between 130 and 230 pounds typically prefer a medium (5) to medium firm (6) feel, while those over 230 pounds tend to get the best results from a medium firm (6) to firm (7-8) feel.
Of course, your individual preferences play a huge role, so make sure to consider what feels right to you even if it doesn’t perfectly align with what normally works best for other side sleepers in your weight group.
| Side Sleeper Weight Range | Firmness Starting Point |
|---|---|
| Less than 130 lbs. | Soft (3) to medium (5) |
| 130 to 230 lbs. | Medium (5) to medium firm (6) |
| More than 230 lbs. | Medium firm (6) to firm (7-8) |
