Best Mattress That Won’t Sag

If you’ve noticed divots or impressions in your mattress, it may be time to buy a new bed. Make the most of your investment with a mattress that won’t sag.

By Natalie Yerger

There’s no worse feeling than buying a new mattress that’s marketed as comfortable, durable and high-quality only to notice sagging or body impressions soon after. In today’s mattress industry, there are thousands of brands, some of which promise their mattresses last more than 10 years when, in reality, they’re made with low-quality materials.

Because of this, sagging is one of the most common complaints from sleepers. All mattresses will begin to sag at some point, but a high-quality bed should hold its shape for at least as long as the company advertises. If you’re in pain on your current mattress or frustrated that every mattress you’ve chosen in the past has sagged quickly, keep reading for our top picks for mattresses that won’t sag.

If you’re interested in a luxury mattress at an affordable price point that you can trust won’t sag, the Saatva HD is a good bet. It’s constructed with a Euro-top cover, comfort layers of zoned latex, high-density memory foam and polyfoam, and a support system of steel coils encased in high-density polyfoam rails. The result is a firm (7/10) feel that’s comfortable yet supportive.

The Euro-top mattress cover adds some plushness to the top of the bed, but the denser comfort layers and foam-reinforced coils offer excellent stability and responsiveness. The Saatva HD should resist sagging, regardless of your body type. A Queen-size Saatva HD costs $2,599 before discounts and promotions are applied. Although this isn’t cheap, it’s a value price compared to other heavy-duty luxury hybrids.

Trial period

The WinkBeds mattress earns our pick for the best mattress that won’t sag for people with back pain. It has a comfy, cool vibe in the top layers and a Euro-pillow top with gel-infused foams to cradle the shoulders. However, it retains a fair amount of firmness and support throughout due to a layer of microcoils and a 7.5” pocketed coil system. The WinkBed is offered in four firmness options (soft, luxury firm, firmer and plus). All have just the right blend of pressure relief to alleviate tension around the back and pushback to ensure sagging, which could create more back issues down the line, doesn’t occur over time.

The WinkBed pockets coil support core is also zoned, including targeted support in the lumbar region that should help alleviate pain. It uses strong coils, ranging from 14.5 to 16 gauge, that are thick and should hold up over time. All sizes of the WinkBed, including the WinkBed Plus for plus-size sleepers, retail for less than $2,000.

Trial period

365 Days



If you’ve been in a cycle of buying mattresses every 2-3 years due to unexpected sagging and simply want the best bed that won’t sag for the money, the DreamCloud is our recommendation. It’s a medium-firm (6.5/10) hybrid constructed with a luxurious cashmere-blend cover, a quilted Euro-top with polyfill and polyfoam, gel-infused memory foam, 8” pocketed coils, and several layers of polyfoam. The bed’s pocketed coils and high-density foams indicate that the mattress should hold up for a long time before it begins to show signs of wear.

This bed excels in supporting sleepers whose needs lean toward the firmer, more supportive side of the spectrum, such as plus-size sleepers and strict back sleepers. It’s also a great choice for couples who’ve struggled with sagging mattresses in the past because it has great edge support to allow them to fully spread out. Side sleepers, stomach sleepers and lightweight sleepers are likely to find the bed too firm.

Helix Plus: Best Mattress for Stomach Sleepers

Helix Plus

Best Mattress for Stomach Sleepers

This 13” supportive hybrid by Helix Sleep is designed for larger sleepers, so it has a dense, supportive feel but still allows for some light sinkage into the top layers for comfort.

If you’re a stomach sleeper, you probably notice sagging in your mattress before any other sleeper type. This is because comfort in this position is dependent upon lift at the stomach and hips, which keeps the spine in alignment and prevents low back pain. As soon as there’s sagging in this area, it can be difficult to fall asleep at night. To make things more challenging, stomach sleepers often struggle to find a mattress that not only offers the support they need but can do so over long periods of time.

While designed for plus-sized sleepers, the Helix Plus can serve as the answer to these problems for almost anyone who’s a stomach sleeper and wants a bed they can rely on to not sag through the torso for years to come. The pocketed coils will work to keep the hips in line with the shoulders, preventing bowing in the low back. Even though the bed has a higher-than-average firmness level (7.5/10), it features two layers of memory foam that, although high-density, provide some cushioning.

Leesa Hybrid: Best Mattress for Combination Sleepers

If you’re a combination sleeper looking for a mattress that won’t sag, a bed’s ability to offer mobility, ease of movement, full-body support and comfort in any position should be top of mind. The Leesa Hybrid is one of the only mattresses we’ve found that checks those boxes for almost any body type while offering durability that’s on par with high-quality mixed-foam hybrid models (at least seven years).

The feel of the Leesa blends contouring from the 3” comfort portion with responsiveness from the coils that should appeal to most combination sleepers. While not as bouncy as other hybrids, it’s responsive enough to make changing positions easy. If you’re a combination sleeper who prefers truly bouncy mattresses, this may not be for you, but those who are okay sacrificing a little bit of bounce for added pressure relief in all three sleeping positions should enjoy it.

Layla Hybrid: Best Flippable Hybrid Bed

Layla Hybrid

Best Flippable Hybrid Bed

The Layla Hybrid features two sides with different firmness levels. It has copper-infused memory foam for cooling, like the original flippable Layla, but swaps the original’s foam core for sturdy pocketed coils to improve durability, breathability and airflow.

The Layla Hybrid mattress is designed to soothe aches while keeping sleepers supported. It’s flippable, meaning that you can choose between two different firmnesses each night. One side is 3/10 and the other is 6.5/10 on the firmness scale, but both have the same vibe: a balance of give with gentle lift.

If you’re looking for a mattress with a one-two punch to prevent sagging, the Layla Hybrid can offer that. It will hold up much better than an all-foam mattress, thanks to the durable coil core, and flipping it regularly should reduce indentations and sagging on either side. Keep in mind that the Layla Hybrid is best for back and side sleepers who are lightweight or average-weight. Plus-size sleepers may enjoy the firm side of the mattress, but both sides are too soft and conforming for stomach sleepers in any weight group.

Big Fig: Best Mattress for Plus-Size Sleepers

Big Fig

Plus-size sleepers can have an especially difficult time finding a mattress that won’t sag over time, even among styles that are known for support, like hybrid and innerspring coil models. Thankfully, select mattress companies have designed mattresses with this sleeper type in mind, and one of them is Big Fig. The Big Fig has a hybrid construction and utilizes both dense foams and springs to support individuals weighing up to 500 pounds and couples weighing up to 1,000 pounds.

Inside the mattress, you’ll find durable gel-infused latex, three layers of firm polyfoam and individually-wrapped, 7” coils. The bed also has a 3” layer of high-density polyfoam around its perimeter to prevent sagging and collapsing around the edges. Keep in mind that those with smaller builds may find the bed too firm, but plus-size individuals and couples will experience initial pressure relief from the quilted cover that’s quickly followed by a sensation of strong support and bounce. It should provide balanced pressure relief and support for plus-size sleepers in all three sleeping positions, and it’s estimated to last up to 10 years without significant sagging.

Purple Hybrid Premier: Best Durable Bed

The Purple Hybrid Premier is a luxury hybrid that contains Purple’s signature Purple Grid comfort layer and supportive pocketed coils.

A quick read of the Purple Hybrid Premier’s warranty reveals that no amount of weight will void the policy, which may speak to Purple’s confidence in the bed’s quality and durability. It’s built with heavy sleepers in mind but is versatile enough to accommodate sleepers of all body types and weights, making it a great choice for those who prioritize durability above all else in a new mattress.

The Hybrid Premier comes in two settings, which vary by firmness and comfort layer (Purple Grid) thickness. One option has a medium-soft (4.5/10) feel and the other has a medium (5.5/10) feel. Their comfort layers consist of the Purple Grid, a hyperelastic polymer material that buckles where pressure is applied yet does not compress elsewhere, creating a unique floating sensation for the sleeper. Hyperelastic polymer may also be more durable than memory foam and other foam types, improving the bed’s resistance to sagging.

In the support core, you’ll find 7.5” pocketed coils. The coils have a gauge of 13.75, making them thick, sturdy and supportive than other hybrid models’ coils. Though the Hybrid Premier is a fairly new mattress and we have not had time to evaluate its average lifespan, our assessment of the materials, quality of construction and owner reviews lead us to estimate that it can perform for up to eight years.

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

Sagging is almost always the result of normal wear and tear on a mattress. All beds will begin to sag at some point, but how fast and intensely that happens depends on the bed’s style, manufacturer, construction, and quality. The cushioning materials in the top layers, like memory foam, latex foam, and polyfoam, soften with prolonged use, especially in areas where the most pressure is applied from the sleeper’s body. Springs and coils also lose tension over time, causing an uneven sleeping surface that can make the mattress feel uncomfortable.

Because we know eventual sagging is inevitable for any mattress, it’s important to select beds with low sagging potential, which can be roughly determined based on a few factors. Here’s what to keep in mind when looking for a mattress that won’t sag:

Mattress Type

Low-quality innerspring and memory foam mattresses tend to have the shortest lifespans. Hybrid mattresses are prone to sagging and body impressions as well, but high-end hybrid mattresses have high-quality foams and coils that tend to be the most durable. High-quality latex mattresses can also last many years without deep impressions.


Firm mattresses with denser materials tend to compress less quickly. If choosing between two mattresses with similar materials that are both suitable in terms of comfort, we recommend choosing the option that is slightly firmer. Our lists of best firm mattresses and best soft mattresses have plenty more information on this subject.

Mattress Materials

As convenient as the bed-in-a-box movement has made online mattress shopping, many affordable beds sold online contain low-quality materials that simply will not last. When selecting a new mattress, do a cost-benefit analysis of buying a slightly more expensive, well-made bed for more money. It may result in costs saved over time as a result of not needing to buy a new mattress every 3-5 years. We also recommend purchasing from mattress brands who are transparent about the details of the materials used in each mattress.

Coil Type

In hybrid and innerspring mattresses, low-gauge (thicker) coils will last longer than high-gauge coils

Foam Types

When buying a foam or hybrid mattress with foam layers, look for foam densities that have a high PCF relative to the norm for that foam type. 1.7+ is considered high for polyfoam and 5+ is considered high for memory foam. We also recommend selecting natural latex over synthetic latex when prioritizing durability.

How to Prevent Mattress Sagging

All mattresses will last longer when properly cared for. While sagging can’t be fixed or completely avoided, there are a few things you can do to minimize it. Or, if you’re past the point of no return, check out our guide on how to fix mattress sagging.

Rotate the Mattress

Most mattresses should be rotated every three to six months to ensure even surface wear. Doing so can significantly extend the lifespan of the mattress by preventing concentrated or premature sagging. If you have a flippable mattress, ensure you’re using both sides by flipping it regularly. Make sure you take a look at our article on flipping your mattress before you do it, though.

Even if your mattress is already showing signs of sagging, rotating it every 3-6 months can help promote even wear down the line. It allows heavier areas of our body (the torso and hips) to rest on areas of the mattress that aren’t yet sagging while giving areas that are forming impressions some relief from the constant downward pressure.

Use a Mattress Topper

If you current mattress has already shown signs of wear, consider adding a topper to increase comfort. A topper adds an additional layer of comfort on top of your existing mattress. They usually feature 2-5” of down alternative, down, foam, latex or wool. If your mattress has deep body impressions, a thicker topper is best. A topper helps with sagging prevention by reducing the direct impact of your body weight on the foam layers of the mattress.

Buy a New Foundation

Much like a house, a solid foundation is essential to the durability and stability of your mattress. If your current mattress is sagging or you’ve noticed that your new mattress purchases sag quicker than expected, it’s a good idea to take a look at your frame, platform bed or foundation. Make sure that it doesn’t have weak wood, separation between slats, saggy or worn boxsprings, or broken slats.

Mattress Sagging and Sleep Positions

Sagging areas in a mattress will be noticeable no matter what your primary sleep position is, but the extent to which it inhibits your ability to get a good night’s rest will vary. Here’s an overview of how sagging mattresses impact sleepers in each position as well as how each position affects a mattress’ longevity.

Side Sleeping

For many, there’s no cozier sleeping position than on the side. The ideal mattress for side sleepers combines pressure relief at the hips and shoulders with support so that the spine doesn’t curve sideways. In fact, if your mattress is too firm, minimal sagging in your mattress around the shoulder and hip joint may actually encourage healthy spinal alignment by allowing these areas to sink more deeply into the mattress.

If you’ve chosen a mattress that’s appropriate for side sleeping and your body type, however, a sagging mattress will encourage too much bend, which may cause pain at the neck, shoulders and low back. Read our mattress recommendations for side sleepers to learn more.

Back Sleeping

Considered the healthiest sleeping position, back sleeping feels best on a supportive mattress that gives lift at the hips to ensure they stay in alignment with the shoulders and lower back. Back sleepers also need pressure relief and conforming in the lumbar region. Back sleepers should pay the most attention to the transition and support layers of a mattress, ensuring they contain high-density foams or quality coils so that the overall vibe of the mattress is supportive.

On a sagging mattress, back sleepers may notice the tension or pain in the lower back as the hips fall beneath the shoulders. Neck and shoulder pain can occur if this area begins to sag as well. Unlike side sleepers, back sleepers do not do well with even minimal sagging, so selecting a mattress that’s ideal for this position and your body type is important. Check out our mattress recommendations for back sleepers to learn more.

Stomach Sleeping

Of all the sleeping positions, stomach sleeping is considered the least healthy because it can cause tension in the neck as the head is placed to one side throughout the night. For those who aren’t willing to learn how to switch sleep positions, there are mattresses available that help make this sleeping position gentler on the body. Stomach sleepers should select a bed that’s firm enough to prevent sagging in the stomach area and supportive enough to bolster the lumbar region while reducing tension at the neck and shoulders.

For this reason, stomach sleepers should avoid softer, less supportive mattresses that will sink and sag quickly. Firm, supportive mattresses with materials known for durability and longevity will prevent spinal misalignment. Head over to our mattress recommendations for stomach sleepers to learn more.
