Why It’s Best Overall

Specifically designed for people who weigh at least 230 pounds, the Helix Plus is an ultra-supportive hybrid that mixes thick foam layers with a robust coil system. The perimeter – a common site for sagging – felt particularly stable, even for our testers in the heaviest weight group. Other strong performance areas for this mattress include motion isolation, pressure relief, and ease of movement.

What It’s Made Of

Designed for plus-size sleepers, the Helix Plus Mattress utilizes high-density foams to prevent premature sagging.

The 13-inch hybrid mattress includes layers of memory foam, responsive polyfoam, and transitional memory foam atop a pocketed coil base. Rows of stronger coils around the perimeter help reinforce the edges, and a polyfoam base layer adds stability to the bed. A Tencel cover provides a breathable sleep surface.

How It Performed

The Helix Plus has a firm (7) feel designed to provide moderate contouring for individuals over 130 pounds. Whereas individuals over 230 pounds may find they sink too deeply into plusher mattresses, the Helix Plus supports the spine in a neutral alignment, especially for back and stomach sleepers. The memory foam also conforms to relieve pressure points.

Thanks to its sturdy build, the model absorbs most motion transfer and makes little to no noise when bearing weight. Most individuals should find the edges hold up well under pressure. Although memory foam is not known for being responsive, the coils in the Helix Plus help ensure sleepers don’t feel stuck in the bed and allow for easier movement. Airflow through the coils also helps prevent excessive heat retention.

Helix provides a 15-year limited warranty, free shipping, and a 100-night sleep trial with a 30-night break-in period.

The DreamCloud Mattress is a hybrid model that balances strong support with a well-cushioned surface. We found the versatile design was a good fit for many types of sleepers – with a reasonable price-point compared to similar hybrid models that we’ve tested.

What It’s Made Of

Measuring 14 inches thick, the DreamCloud has a medium firm (6) feel. The cover is made of a moisture-wicking cashmere blend quilted with polyfoam. Beneath this lies a layer of gel-infused memory foam and an additional layer of transitional polyfoam. The support core contains pocketed coils that rest atop a polyfoam base.

How It Performed

The balanced feel of the DreamCloud Mattress lends itself well to side, back, and stomach sleepers of most weight ranges, although side sleepers under 130 pounds may find the bed too firm. With its pocketed coil support core, the mattress has a slight responsive feel that enables combination sleepers to easily switch sleeping positions.

The memory foam and polyfoam layers help absorb movement, helping couples experience minimal disruptions when one person rolls over or gets in and out of bed. With individually wrapped coils, the DreamCloud is also fairly quiet.

Although memory foam is notorious for trapping heat, the gel infusions are designed to draw heat away from the surface of this mattress so it can dissipate through the coils.

DreamCloud offers a lifetime limited warranty and a 365-night sleep trial with a 30-night requirement. Shipping is free for customers in the contiguous U.S.

An innerspring mattress with a firm (7) feel, the 15.5-inch Saatva HD is designed with heavy-duty elements engineered to support sleepers up to 500 pounds without compromising  pressure relief. This is a strong option for shoppers who are willing to spend a little bit more money for a bed with superior support.

What It’s Made Of

The Saatva HD has a breathable organic cotton cover certified by the Global Organic Textile Standard (GOTS). Quilted polyfoam adds extra padding with an integrated, hand-tufted Euro-top design. The comfort system also includes five-zone natural Talalay latex and memory foam. These layers contour to the sleeper and provide additional support to the lumbar area to help prevent pressure buildup.

The support core consists of a layer of thick 12.5-gauge innerspring coils. The coils feature a polyfoam encasement around the perimeter, allowing more usable surface area for sleepers. The layer also has a spinal zone wire for additional lumbar support.

How It Performed

The Saatva HD helps maintain spinal alignment for back and side sleepers over 130 pounds. It also supports stomach sleepers across all weight categories, and the combination of latex and springs helps facilitate movement.

This model stands out for its temperature neutrality. The latex is perforated with tiny holes to increase heat dissipation, and the innerspring support core allows air to flow freely.

33% off all Nectar products

The Nectar Premier Copper is an all-foam mattress that offers the quintessential deep body “hug” of a foam bed. While foam beds are known for trapping heat, this model is designed with cooling features that are meant to keep the surface cooler and more comfortable.

What It’s Made of

The bed has a medium firm (6) feel. The comfort layer is composed of memory foam measuring 4 inches thick, creating a supportive yet adaptive feel as your body settles into the surface. A polyfoam transitional layer provides extra cushioning, and the high-density foam support core stabilizes the entire mattress.

The cover is a breathable blend of polyester, polyethylene, and nylon. Copper fibers woven into the fabric are intended to reduce heat buildup on the surface. For additional temperature control, the memory foam is infused with phase change material (PCM) that dissipates heat on contact. The Premier Copper measures 14 inches thick, giving it a higher profile than most memory foam mattresses sold today.

How It Performed

As an exceptionally thick and medium firm foam mattress, the Premier Copper earned favorable ratings from the side sleepers on our team across all weight groups. Those weighing at least 130 pounds were particularly impressed with the even contouring and steady support of this mattress, as were back and stomach sleepers under 130 pounds.

Our testers detected virtually no movement from the other side of the bed during our motion isolation tests. The foam layers collectively absorb movement very well, including instances when we changed positions or got off of the mattress. We also found the Premier Copper to be highly effective at alleviating pressure points along the spine. Our body sensors picked up minimal pressure buildup for most of the testers. Although the mattress may still sleep too warm for some, the cooling components help the surface maintain a reasonably comfortable temperature – especially compared to other all-foam models.

The Premier Copper’s sticker price reflects its luxurious design, but Nectar offers free shipping for all orders within the contiguous U.S. Your purchase also includes a generous sleep trial allowing you to test the mattress for up to 365 nights before deciding whether to return it or keep it. If you opt for the latter, you’ll also receive a lifetime warranty against excessive sagging and other structural defects.

Sleep Foundation Exclusive Offer!

Get $300 off all mattresses

The WinkBed is available in four firmness options, but the WinkBed Plus caters specifically to sleepers who need enhanced support. We found the sturdiness of this hybrid model also makes it a great option for sleepers who need extra support to reduce back pain during sleep.

What It’s Made of

As a mattress designed for people who weigh more than 230 pounds, the WinkBed Plus begins with a top layer of high-density polyfoam and a second layer of zoned latex. Both of these materials are highly responsive, adding extra bounce to the surface and reinforcing the firm (8) feel. A Euro-top surface adds some plushness for comfort without sacrificing the Plus’s supportive qualities.

The support core contains 7.5-inch pocketed coils in a zoned arrangement. Thicker coils lie beneath the midsection to provide push-back and prevent sagging around the sleeper’s heaviest areas. The coils are also bolstered along the perimeter to reduce sinkage when you lie near or sit along the edges. A cover made of breathable, moisture-wicking Tencel fabric encases the mattress.

How It Performed

The WinkBed Plus performed well across the board during our hands-on tests – no small feat for a mattress this firm. The testers who felt most comfortable were those weighing more than 230 pounds, but the Plus also fared better than expected with lighter sleepers. This was especially true of testers who primarily use the back and stomach positions.

The latex retains very little heat, air flows freely through the coils, and the Tencel cover is both breathable and absorbent. As a result, the Plus is a great choice for people who frequently sleep hot or sweat in bed. The zoned coils also provide excellent push-back to ensure little to no sinkage around the torso and hips, as well as superior perimeter protection.

WinkBeds offers free ground shipping throughout the contiguous U.S. Each order comes with a 120-night trial. If you find the Plus too firm, you may exchange the mattress for a model with a different firmness level at no extra charge. WinkBeds are backed by lifetime warranties.

The Titan Plus is one of the firmest hybrid models we’ve tested firsthand. Rating as an 8 on our 10-point firmness scale, the mattress feels exceptionally supportive and maintains a flat, even surface for most people – even those weighing more than 230 pounds.

What It’s Made of

A thin layer of memory foam is quilted into the cover, followed by 2 inches of dense polyfoam. These materials provide light cushioning. The support core consists of thick pocketed coils over a base layer of high-density polyfoam. We found that the Titan Plus sleeps reasonably cool. If you are a hot sleeper, you can opt to include a phase change material (PCM) panel sewn into the cover. PCM is engineered to capture and release body heat on contact, creating a surface that feels cool at all times. Measuring 11 inches thick, the Titan Plus is considered a medium-profile mattress.

How It Performed

As a relatively firm mattress, the Titan Plus performed well in areas where softer, more adaptive hybrids tend to struggle. These include temperature control, ease of movement, and edge support. Our tester encountered little resistance moving across the surface, and no one sank excessively when positioned near or along the perimeter. The cooling panel makes a noticeable difference to the surface temperature, but we also found the mattress comfortable without the panel.

During our hands-on tests, we found the Titan Plus best suited to people over 230 pounds across the side, back, and stomach sleeping positions. The mattress offers plenty of support, which sleepers in this weight range often need. Back and stomach sleepers between 130 and 230 pounds also found the mattress comfortable.

The Titan Plus is available in seven sizes, including a split king for couples who share adjustable beds. The price-point falls well below average for a hybrid and shipping is free throughout the contiguous U.S. Your purchase comes with a 120-night sleep trial, and you’ll also receive a 10-year manufacturer’s warranty if you decide to keep the mattress.

Sleep Foundation readers get the best price on Casper products.

The Casper Wave Hybrid is a foam and latex hybrid mattress that balances pressure relief, responsiveness, and cooling. The thoughtful construction makes this an excellent choice for side sleepers seeking a bed that cradles sharp pressure points while still delivering support.

What It’s Made of

Perforated Airscape polyfoam coated with cooling gel makes up the top comfort layer. The perforations help facilitate airflow while the cooling gel is meant to reduce heat buildup. Next is a layer of responsive latex foam that is naturally breathable. This layer gently cradles the body to relieve pressure, but it shouldn’t sink too deeply under a sleeper’s weight. Underneath is a layer of zoned memory foam that targets the hips and shoulders to alleviate pressure buildup.

A second layer of Airscape polyfoam acts as a transitional layer between the comfort system and the support core. The polyfoam has gel pods that provide targeted support to the hips and shoulders. The support core’s pocketed coils move independently to limit motion transfer and promote spinal alignment. A breathable cover made from recycled polyester, upcycled cotton, rayon, and lycra encases the mattress.

How It Performed

The Wave Hybrid has a balanced medium (5) feel that can suit many sleepers. Our testing lab found that side sleepers between 130 and 230 pounds and back sleepers under 130 pounds were most comfortable on this model. These sleepers appreciated the thick comfort system that targets pressure buildup in the hips, shoulders, and lower back. Meanwhile, the pocketed coil support core keeps the body on an even plane.

Our testers found the mattress excelled in a few categories, namely motion isolation and temperature regulation. Couples should appreciate the comfort system’s ability to absorb most movement and noise. You should notice very few sleep interruptions from your partner changing positions at night. Foam layers often retain excessive heat, but the aerated foams and breathable coil support core ensure the internal temperature stays cool.

Customers can try out the Wave Hybrid with Casper’s 100-night sleep trial, where customers can return mattresses after a 30-night break-in period. Mattress purchases come with a 10-year warranty, and shipping is free to customers in the contiguous U.S.

The Birch Luxe is a hybrid model that combines a sturdy coil base with wool and latex layers on top. The contouring offered by the Euro-top surface makes this a good fit for those who need cushioning for sharp pressure points during sleep.

What It’s Made Of

Crafted with organic and natural materials, the Birch Luxe measures 11.5 inches thick. The mattress has a Euro-top organic cotton cover with an organic wool and rayon fire barrier. Additional layers of cashmere and wool help wick moisture away from the mattress surface and add responsive pressure relief.

Natural latex in the comfort system adds responsiveness and supplies a firmer transition to the pocketed coil support core. The coils feature targeted lumbar support and perimeter reinforcement. A second wool and rayon fire barrier completes the base.

The cashmere, wool, and cotton are certified organic by GOTS, and the mattress holds Greenguard GOLD certification for low chemical emissions. Additionally, the natural materials don’t off-gas like foam mattresses, which may be an advantage for sleepers who are sensitive to smell.

How It Performed

The Birch Luxe has a medium firm (6) feel that provides balanced support and pressure relief for back, side, and stomach sleepers. As expected from a latex hybrid mattress, this model also has a highly responsive surface that makes it easy to change sleep positions.

Due to its exceptionally breathable construction and moisture-wicking wool layers, the mattress retains little to no heat, helping sleepers stay at a comfortable temperature all night long.

The Birch Luxe ships free to the contiguous U.S. and to Canada for an additional fee. Shoppers receive a 100-night sleep trial with a 30-night break-in period. The mattress is also protected by a 25-year limited warranty.

Why You Should Trust Us

Finding a mattress that will stand the test of time can be a challenging task, especially since many newer manufacturers don’t yet have a proven track record. Our experts are well-versed in mattress construction, and our vast experience has helped us learn how to identify well-built designs with a long-expected lifespan.

We back our recommendations with an extensive testing process during which we analyze every facet of the mattress, including how it performs for people with different body types and preferred sleep positions. Because sleepers over 230 pounds exert more pressure on mattresses, our team incorporates sleepers in this weight range as well.

What Causes a Mattress to Sag?

Over time, foam breaks down and coils lose their ability to spring back to their original shape. Both of these issues can result in sagging. Most mattresses will sag eventually, but the quality of construction and materials can accelerate or delay the occurrence.

Premature Sagging vs. Normal Wear and Tear

There are two primary components to a mattress: the comfort system and the support core. Ultimately, every layer of the mattress affects its propensity to sag. The comfort system is more prone to localized body indentations, whereas the support core can cause broader structural problems.

Support Core: The support core is usually made of sturdy materials such as steel springs or high-density polyfoam, which are designed to withstand repeated use before they start breaking down.

Mattresses with low coil counts or low-quality steel are quicker to lose their elasticity, and they generally sag sooner than higher-quality builds. A hybrid mattress made with low-quality coils may only last 5 to 6 years, whereas a better-quality base may lengthen the expected lifespan up to 8 or 10 years.

Likewise, low-density polyfoam with thinner cell walls and more air pockets is more susceptible to sagging. Lower quality all-foam models can break down as soon as 2 or 3 years after purchasing, whereas better models may last up to 7 or 8 years.

Comfort System: The comfort system tends to include softer materials such as memory foam, which can break down sooner and develop permanent indentations. Additionally, mattresses with thicker comfort sections may be more vulnerable to forming body impressions. To a certain extent, this wear and tear is considered a normal part of mattress use. Sometimes, manufacturers add firmer transitional layers to reinforce the softer layers on top.

Most manufacturers don’t cover sagging and body indentations under warranty unless they reach a certain level, such as 1-inch indentations that are visible even when no pressure is applied. If your mattress has body impressions that are not covered by the warranty and you find they affect the mattress’ ability to provide pressure relief, you may be able to compensate by using a mattress topper.

Although the warranty length and terms do not always correspond to the quality of the mattress, these can be a good indication of how long the manufacturer expects the bed to last. Warranties that cover body impressions of at least 1 inch⁠ — as opposed to impressions of 1.5 or 2 inches ⁠— indicate that the construction will likely prevent premature sagging.

Similarly, longer warranties of 15 or 20 years imply that the mattress may last longer before needing to be replaced. These models are often more expensive up-front, but the price may be worthwhile if it saves you the cost of buying another new mattress within that time frame.

How to Choose a Durable Mattress

There are several indications that hint at when a mattress may start sagging, such as the price, the type of materials, and the firmness level. When purchasing a mattress, you should also consider factors that influence the overall comfort, such as temperature regulation and motion isolation, as well as whether the mattress design is appropriate for your body type and sleeping position.

What to Look For in a Mattress That Won’t Sag

Mattress shopping can be overwhelming, as every manufacturer has its own terms to describe proprietary materials. Understanding how the different mattress components contribute to its overall feel and performance can help you narrow down your choices and find a bed suitable for your needs.

Mattress price is an easy way to weed out low-quality mattresses. While prices can vary according to brand, special features, or organic certifications, a cheap mattress will generally sag sooner. These beds may be suitable for guest rooms, but they likely aren’t designed to withstand regular use.

Sleeping Position
Proper spinal support is important no matter what sleeping position you prefer. However, a sagging mattress may be most uncomfortable for stomach sleepers if it allows the midsection to sink in too much. Back sleepers also require a reliable surface to support the lumbar spine.

Quality Materials
Mattresses built with natural materials such as latex and wool tend to outlast other materials. When assessing the quality of your mattress, note the coil count, the coil gauge or thickness, the foam density, and any vulnerable points that may be more susceptible to premature sagging, such as convoluted polyfoam. Look for manufacturers that are transparent with their specs.

Firmness Level
The right firmness level for you depends on your body weight and primary sleep position. Broadly speaking, firmer mattresses tend to be more resistant to body impressions, although there are many exceptions as this also depends on the materials used. Stomach sleepers and individuals who weigh more than 230 pounds may find that a firm (7) or extra firm (9) mattress offers longer-lasting support.

Pressure Relief
Pressure relief is a key factor for all sleepers, especially for side sleepers and those who weigh under 130 pounds. These sleepers can experience pressure points where the hips and shoulders make contact with the mattress, so they benefit from having cushioning materials in the comfort system. High-density memory foam, natural Talalay latex, and wool are examples of pressure-relieving materials with a long-expected lifespan.

Motion Isolation
For people who sleep with a partner, it’s important to find a mattress that doesn’t transfer motion across the bed. All-foam models and hybrids with individually wrapped coils tend to perform well at motion isolation.

Temperature Regulation
Temperature neutrality is especially relevant to hot sleepers and those who live in warm climates. Mattress manufacturers use many techniques to fight against heat retention. For example, mattresses can include moisture-wicking covers, and foams may be perforated or infused with gel beads designed to draw heat away from the bed’s surface. Innerspring cores also perform well at temperature neutrality, as their construction allows air to flow freely through the coils.

Edge Support
Whereas hybrid and innerspring models usually feature a reinforced perimeter, foam and latex models may compress significantly when weight is placed on the edges of the bed. Weak edge support can significantly limit the usable surface area, so it’s an important consideration for people who like to sit on the edges, partners who share a smaller bed, or those who have trouble getting in and out of bed. Foam mattresses may break down sooner, so if you value edge support, consider a bed with a firmer, thinner comfort system.

Contouring refers to a material’s ability to mold itself to the sleeper. Mattresses that contour more closely tend to provide better pressure relief, but they may be more apt to develop body impressions over time. Ideally, the comfort system should provide a certain level of contouring, while the transition layers and support core help bolster spinal support and enhance durability.

Mattress Type
Mattresses are classified into different types according to the primary materials used in their construction. While every model is unique, the mattress type plays a significant role in its performance and durability. Latex and hybrid mattresses often outperform foam and innerspring models when it comes to durability.

Mattress Types

The primary mattress types include hybrid, innerspring, foam, latex, and airbed. Mattress type is mainly determined by the materials used in the support core. While a mattress type can describe general characteristics, there can also be variations from model to model depending on the design and the quality of the materials.


Hybrid mattresses combine a substantial comfort system with an innerspring core, which is typically made with pocketed coils to reduce noise and motion transfer. The comfort layers may incorporate polyfoam, memory foam, latex, wool, cotton batting, microcoils, or other pressure-relieving materials.

Hybrid mattresses offer better pressure relief than classic innerspring models, and they also tend to boast sturdy edge support and strong breathability due to the coil layer. This makes them ideal for hot sleepers and those who enjoy using the full surface of the bed.

When looking for a hybrid mattress that won’t sag, aim for a minimum of 1,000 coils in a queen size and dedicated reinforcement around the perimeter. In the comfort system, high-density foams or natural materials like wool or latex are usually the most durable.


Sleepers who favor bounce, edge support, and airflow may be interested in an innerspring model. This mattress type is made almost exclusively of tempered steel coils, with little to no comfort system. These features make innerspring mattresses suitable for stomach sleepers but less suitable for side and back sleepers.

The durability of an innerspring mattress can vary greatly depending on the type, the gauge, and the total number of coils. Thicker-gauge coils and designs such as offset coils can withstand more pressure without losing their resilience. By contrast, older designs such as Bonnell coils may start sinking sooner.

It’s good practice to ensure your mattress has an appropriate coil count for the type of coils used, though several other factors influence a mattress’ performance. Similarly, coils may have different functions depending on their gauge and placement in the mattress. Many manufacturers use thicker low-gauge coils to strengthen the edges and thinner high-gauge coils for the hips and shoulders.


Foam mattresses contain polyfoam, memory foam, latex, or textiles in the comfort system and sit above a polyfoam support core. Ideally, the support core uses durable high-density polyfoam with a density of at least 1.8 pounds per cubic foot (PCF).

Couples often prefer foam mattresses because the lack of springs allow less motion to transfer to the other side of the bed when one person moves. Models with memory foam in the comfort layers also offer unparalleled pressure relief for side sleepers and individuals under 130 pounds. Sleepers over 230 pounds, however, may find that foam mattresses lack sufficient support.

In addition to the foam density and quality of the materials used, the thickness of the comfort system can also affect a mattress’ lifespan. Thicker comfort systems are more likely to develop body impressions, especially if they are made with low-quality materials.


Natural latex is made from sap found in rubber trees, which is whipped into a froth and baked using either the Dunlop or the Talalay process. Dunlop latex tends to be denser on one side, whereas Talalay is more buoyant and uniform. Latex can also be made synthetically using petrochemicals.

Natural latex is considered one of the most durable mattress materials, making it highly resistant to sagging. It can be used in the comfort or support layers, and it is often aerated with pincore holes to improve breathability. Mattresses made with certified organic latex may be appealing to sustainably minded shoppers.


Airbeds use air chambers as the support core, which can often be inflated or deflated by the user until they reach the desired firmness level. Provided there are no leaks in the air chambers, this system should be protective against sagging as more air can always be added to increase the firmness setting.

Sleepers who want adjustable firmness levels or couples with differing comfort preferences may be interested in an airbed, as each side of the bed generally includes its own customizable air chambers. Airbeds may have additional layers of polyfoam, memory foam, or other materials to supplement the air chambers as well.

Extending the Lifespan of Your Mattress

By adopting a few proactive habits, you can help keep your mattress in tip-top shape for a longer period of time and delay when you need to invest in a new one.

Use a Mattress Protector and Clean Regularly
A mattress protector is a thin, waterproof membrane designed to protect your mattress against spills and stains. Not only does this help prevent accidental damage to your mattress, it can also prevent you from inadvertently voiding your mattress warranty, as most manufacturers won’t cover mattresses with visible stains.

Rotate Your Mattress
Most mattresses sold today aren’t designed to be flipped. However, you can delay the onset of permanent body impressions by rotating the mattress head-to-foot every 3 to 6 months.

Use Proper Support Under The Mattress
A proper foundation is essential for keeping your mattress supported and preventing pressure points from improper spinal alignment. Consult the manufacturer’s website or the warranty terms to find out what type of base is recommended for your model. Generally, a solid or a slatted foundation will offer sufficient support. You may need to ensure the slats are close enough together to prevent sagging. A full mattress or larger may require additional support in the center of the bed.

Frequently Asked Questions

  • What are the pros and cons of a gel mattress?

    Gel mattresses aim to offer a cooler sleep experience, which can raise the price-point compared to regular foam mattresses. Gel foam is a good option for sleepers who like the pressure-relieving, motion-isolating feel of memory foam or polyfoam but don’t like sleeping hot.

    Because gel must be added to either memory foam or polyfoam, gel mattresses may not be attractive to shoppers who prefer natural materials or those who are sensitive to off-gassing smells.

  • What kinds of gel mattresses are available?

    As gel foam is meant to be used in the comfort layers, gel mattresses can come in either hybrid or all-foam models. All-foam models have a high-density polyfoam support base, whereas hybrid mattresses have an innerspring base that is often made with pocketed coils. More rarely, shoppers might see airbed models with gel foam comfort layers over an inflatable air chamber.

  • How much does a gel mattress cost?

    The average price of a gel mattress runs from about $800 to $2,000, though there are plenty of models that fall outside of this range. Foam mattresses are among the cheapest options, while hybrids may be more expensive. Although gel foam is more expensive than regular memory foam or polyfoam, gel mattresses usually cost less than natural latex mattresses.

    Pricing can change depending on the brand, the design of the mattress, the quality of the materials, and the shipping and return policies. If you want the feel of gel foam but not the investment in a new mattress, a gel foam mattress topper may also be an option.

  • How long does a gel mattress last?

    On average, buyers can expect a foam or hybrid mattress to last 6 to 8 years if properly cared for.

    With all mattresses, the comfort system generally starts to break down before the support core. As a comfort layer, gel foam is not the most durable material, especially in its plusher iterations. However, regularly rotating the mattress from head to foot can delay the onset of permanent body indentations. Using a mattress protector can also help extend the lifespan by shielding the material against accidents.
