One of the many mattress models that Helix offers, the Dusk features the same quality materials, impressive construction, and reasonable price point. The dynamic top layer combines latex and foam to create a mattress surface that caters to all sleeping positions, and the memory foam and innerspring layers contribute to the above-average motion isolation and pressure relief.
All of these qualities make the Helix Dusk a great mattress, but the two characteristics that earn it the award of editor’s pick for mattresses that won’t sag are its durability and its edge support. Despite the affordability, we found the Dusk to have sturdiness that indicates a long lifespan, and the surface has a dense feel that holds up well under significant weight.
Plus, a 100-night sleep trial gives some peace of mind to those wary about buying a mattress online.

Best Innerspring Mattress
- Sleepers who like a “springy” feel
- People with joint pain
- Multiple firmness options
Recognized as one of the premier innerspring hybrids available on the market today, the Saatva Classic has also been praised for its ability to meet the pressure relief needs of side sleepers as well as individuals who suffer from back pain. This highly rated mattress comes in varied firmness options and scores perfect or near perfect marks in durability due to the dual support coil system and spine alignment.
Additionally, Saatva promotes breathability and airflow thanks to its innerspring system, which will help hot sleepers remain cool and comfortable throughout the night. The Saatva pillow top mattress is a good choice for heavier sleepers as well, as it can hold up to 600 pounds of body weight overall—up to 300 pounds per side.
Finally, the Saatva mattress also does well in terms of edge support because of its dual perimeter edge support layer. The mattress also offers a plush, quilted Euro pillow top that will deliver high levels of comfort as you sleep. You get a 365-night trial and a lifetime warranty with purchase.
WinkBeds Luxury Firm
Best Pillow Top Mattress
- Choice of four firmness options
- Back and stomach sleepers
- People who sleep hot
Medium firm: 6/10
WinkBed makes some of the sturdiest beds that we’ve tested here at Mattress Advisor. Scoring a perfect 10/10 for durability, the original WinkBed holds up under substantial weight, meaning couples and plus-size sleepers can rest with peace of mind in the knowledge that the mattress has their backs.
You might be thinking that a mattress as sturdy as the WinkBed can’t possibly also be plush and cozy. Well, thanks to the Hypersoft pillow top and gel foam comfort layer the WinkBed accomplishes both.
We tested the Luxury Firm option of the WinkBed, which we highly recommend, but depending on your preferences you may be more inclined to try the Softer, Firmer, or Extra Firm version instead.
Brooklyn Aurora Luxe
Best Mattress for Back Pain
- Side sleepers and back pain sufferers
- Sleepers who tend to run hot at night
- Shoppers who want to choose from different firmness levels
Available in soft (3/10), medium (5/10) or firm (7/10)
The Brooklyn Bedding Aurora Luxe is a top pick for sleepers who deal with back pain. It is one of the best hybrid mattresses available today and shoppers who want varied firmness levels can choose from firm, medium, and plush options. The bed’s five layers are made of support foam, innerspring coils, memory foam, and cooling materials.
This bed is also heralded for its ability to sleep cool and remain breathable all night long. Its top layer is cool to the touch and it also scores well for responsiveness, spine alignment, and motion transfer. The firm mattress option is specifically recommended for stomach sleepers and back sleepers who want to alleviate their back pain and realize improved lumbar support. The soft mattress, in turn, is ideal for side sleepers who require relief of pressure points and appreciate sleeping “in” a mattress as opposed to “on” the mattress.
The company offers a 10-year limited warranty and a sleep trial of 120 nights on this hybrid mattress. Brooklyn Bedding provides free returns and you will receive your new bed-in-a-box within four to eight days of placing your order.
Best Mattress for Combination Sleepers
- Sleepers who change positions
- Athletes and active lifestyles
- Restless sleepers
Medium firm: 6.5/10
Combination sleepers need a responsive mattress that makes it easy for them to change sleeping positions without exerting too much energy. They should find a lot to like about the original Bear mattress, thanks in part to its 9/10 responsiveness score.
The Bear was also created with athletes in mind, which is why it uses Celliant material designed to help promote muscle recovery. Despite it being an all-foam mattress, it does a great job of dispersing your body heat rather than trapping it. We were so impressed by its ability to regulate temperature that we gave it a 9/10 on our cooling test.
As far as sagging goes, we feel confident that the Bear will maintain its structure for quite some time. Its scores in durability (8/10) and edge support (8.5/10) indicate a mattress that holds up well. Also, Bear offers a limited lifetime warranty.
Best Budget Mattress
- Value shoppers
- Fans of memory foam
- Side sleepers
If you’re looking for a mattress that won’t sag at a price that won’t shock, put the original Nectar Memory Foam on your list. Nectar is well known as a source of affordable mattresses, and the Nectar has qualities that make it a good bet to resist sagging.
The mattress receives 9/10 for edge support in our testing lab, which means outstanding support across the entire surface. For durability, the Nectar original scores a solid 8.5. It’s also a 6/10 on the firmness scale.
Despite an unremarkable score for cooling (7.75/10), the Nectar’s all-around performance is solid. Budget-minded shoppers interested in a mattress that won’t sag, especially side sleepers, will find a lot to like about Nectar’s original model.
Best Firm Mattress
- Sleepers who like a firm feel
- Dual-sided firmness options
- People above average weight
When it comes to firmness, this mattress more than lives up to its name. The Plank Firm is a flippable mattress with a firm side (7/10) and an extra-firm side (9/10). It’s also designed to be sturdier than the typical all-foam bed, thanks in large part to a high-density polyfoam core that makes it a solid choice for a sag-resistant mattress.
In Mattress Advisor testing, the Plank Firm earns high marks for pressure relief (9/10) and spine alignment (8.75/10), encouraging signs for people with back pain. The dual firmness options also match up well with heavier people. The Plank Firm’s cooling performance (8/10 score) is a bit above average for an all-foam mattress, although you can add a GlacioTex Cooling Cover for an additional charge.
Like other Brooklyn Bedding mattresses, the Plank Firm has a 10-year warranty and a 120-night sleep trial.
Best Mattress for Hot Sleepers
- Sleepers who get overheated
- Fans of latex foam beds
- Average-weight sleepers
The Nolah Natural 11″ is a great choice for hot sleepers who want a sag-resistant mattress that combines durability and breathability. The latex/coil hybrid earns a 9/10 Mattress Advisor cooling score, which compares very favorably with some of today’s best cooling mattresses.
Durability is built into the design, thanks in part to cotton and wool layers that support the coil system. In fact, we give the Nolah Natural a 9/10 durability score. Its 5.5/10 firmness should provide a good match for average-weight sleepers in most sleeping positions, and the 9/10 pressure relief score is a promising sign for people who have joint pain.
Nolah seems pretty confident that its mattresses will hold up over the long haul, since the company offers a lifetime mattress warranty. You also get a 120-night sleep trial to try out the Nolah Natural 11″.
Best Mattress for Heavy People
- Heavy people
- Spinal alignment
Long-lasting mattresses and mattresses for heavy people have one crucial thing in common: adequate support and quality materials. The Titan Plus checks both of these boxes. After all, it’s made for heavier people by Brooklyn Bedding, a mattress brand that excels in mattress manufacturing.
While testing, the Titan Plus’s edge support didn’t overly impress us (a 7.5/10), but its near-perfect durability score makes up for it (9/10). For heavier people, the Titan Plus scores a 9.5/10 in spinal alignment, so sleepers should rest assured that this mattress will be able to support good alignment for years to come.
This strong support is thanks to Brooklyn Bedding’s signature high-density foam and sturdy pocketed coils. The company provides customers with a 10-year warranty and a 120-night sleep trial.
Puffy Lux Hybrid
Best for Easy Set-Up
- Quick set-up after delivery
- Lifetime warranty
- Pressure relief for back pain
Medium-Firm - 6/10
Unless you can get white-glove delivery, setting up your new bed-in-a-box mattresses just comes with the territory. Fortunately, it took our reviewers just over 2 minutes to unbox, unwrap and unroll the Puffy Lux Hybrid.
The Puffy Lux Hybrid doesn’t excel in edge support in our testing and review process, scoring a 6.5/10. However, it does show promise in other areas that indicate a quality mattress that resists sagging: an 8/10 score for durability and 6/10 on the firmness scale). Average-weight sleepers who want pressure relief for their lower backs should find a lot to like about this mattress.
Puffy also offers a lifetime warranty, which shows the company is confident about how long its mattresses will hold up.
Lying on a mattress that’s caving in can be frustrating and, more important, not conducive to a good night’s sleep. A sagging mattress could also lead to painful nights and painful mornings if your body weight is distributed unevenly, causing excess pressure on muscles and joints.
The remedy is finding a durable mattress that keeps its resilience longer than the typical bed. In this guide, we’ll explore what makes mattresses sag, which types of mattress are more resistant than others, and how you can choose the right bed for the long haul.
- What Makes a Mattress Sag?
- Which Mattress Types Resist Sagging?
- How to Choose a Durable Mattress
- How to Extend the Lifespan of Your Mattress
So what can make a mattress lose its support and start caving in? Here are the main reasons why:
- The force of a person’s weight pressing down on the surface for several hours a night, night after night, will gradually create an impression in the material. Even memory foam, designed to contour to your body and gradually spring back to the original shape, doesn’t maintain its original elasticity forever. Sudden impacts also contribute to sagging (which explains why Mom told you not to jump on the bed).
- Mattress material can also contribute to the sagging process. Low-quality, low-density foam and latex have less longevity. With innerspring mattresses, coils that use tempered steel and other durable materials won’t lose their tension as quickly.
- Using a foundation that doesn’t provide adequate support can also cause a mattress to sag before its time. An under-performing foundation makes the mattress bear more of the burden, so getting the right foundation for your mattress is essential.
- Mattresses on the lower end of the firmness scale are typically more prone to sagging, since they have more “give” than something firmer. Firm mattresses and medium-firm mattresses should hold up longer.
Your best bet is to find a mattress that resists sagging thanks to quality materials and design. Two important qualities to look for are edge support and durability, both of which are included in Mattress Advisor’s testing and review process.
Mattresses that are made from innerspring coils alone aren’t ideal, but hybrid innerspring mattresses that have layers of different materials usually do quite well at resisting sagging. Look for a mattress that uses low-gauge coils because they will keep their strength longer.
Memory Foam Mattress
If you decide to purchase an all-foam memory foam bed, it is imperative that you choose a new bed that has high-density memory foam or high-density polyfoam. Plush memory foam mattresses that have lower density foam used in their manufacture will be more likely to sag. For a long-lasting mattress that won’t sag, opt for high-density foams.
Latex mattresses have become increasingly popular in recent years and with good reason. These beds are very comfortable, offer superb contouring and cushioning, and deliver bouncy support. Additionally, latex is one of the best durable mattress materials on the market and known to last long. Because latex beds are so strong, they are unlikely to experience sagging as time passes.
Comprised of memory foam, latex foam, and innerspring coils (or any combination), hybrid mattresses deliver multiple comfort layers and great support. However, what makes a hybrid mattress likely or unlikely to sag is really centered on the quality of the bed itself and the materials used in its manufacturing process.
High-density memory foam, latex foam, and the use of low-gauge steel springs will make sagging less likely. On the flip side of this, high-gauge innerspring coils and low-density memory foam can reduce the lifespan of your mattress and make it less durable.
How to Choose a Durable Mattress
Is a mattress that starts to sag after just a few years a deal-breaker for you? Here are key factors to consider as you’re shopping for a durable mattress.
Quality of Materials
Let’s look at the materials that help ensure you’re getting a high-quality product.
- Foam—Memory foam’s tendency to revert to its original shape helps it resist sagging. Memory foam is more likely to resist sagging better than non-memory polyfoam, which gives a high-quality memory foam mattress a typical lifespan of 7-10 years.
- Latex—All-natural latex (especially Dunlop latex) has exceptional durability, better than synthetic latex or natural/synthetic latex blends. While latex mattresses tend to have the longest lifespan of any mattress type (8-15 years), a natural latex bed could last even longer.
- Coils—The most durable type of mattress springs are low-gauge, individually wrapped pocketed coils, which are thicker and move independently. Coil count matters too, since more coils means better weight distribution. Look for at least 300 coils with a full-size, 400 with a queen and 480 with a king. The right combination of coil design and coil count can help an innerspring mattress last 6-8 years.
If you’re getting a hybrid mattress that combines different types of materials, look for these same standards in every layer—high-density foam, natural latex, and low-gauge pocketed coils.
Edge support measures how well a mattress provides support on the edges of the bed. You can feel it if you lie down on your mattress and notice how the edge starts to compress as you roll away from the center.
Some beds are more likely to sag around the edges based on the design and materials. If edges start to lose their resilience, the usable surface area of your mattress is reduced.
If you’re looking for a bed that offers strong edge support, consider a hybrid or innerspring mattress. These types of mattresses are often held together by sturdy encasements. If you want edge support with a soft top layer, go with euro-top vs. pillow-top. A euro-top’s edges are sewn to the sides of the mattress rather than sitting on top of it. Euro-tops are usually thicker and more durable, too.
A mattress that keeps its support and resilience is not only good for your sleep routine but also your wallet.
When shopping for a durable mattress, you may notice higher prices for better quality. However, you may save money in the long run since a high-quality mattress won’t need to be replaced as soon as a cheaper mattress. A $1,000 mattress that lasts a decade is more cost-effective than a $500 mattress that starts to sag after three years and is ready for replacement at four.
If you must go for the rock-bottom price on a mattress, at least make it the one that you put in your guest room instead of the one you plan to sleep on every night for years to come.
How to Extend The Lifespan of Your Mattress
Most mattresses are built to last 5-10 years, but you can extend the life of your mattress with a few simple tips. If you practice some of these habits, you can keep your mattress in great shape and delay any sagging or other issues that come with regular use.
Use the Right Foundation
Many mattresses require a mattress foundation, such as a frame or box springs. Using a foundation reduces the chances of a mattress warping or sagging, making it a longer-lasting investment. Always use the foundation recommended by the manufacturer, to get the best results and so that you don’t void your warranty.
Flip or Rotate Your Mattress
Over time and with regular use, your body will make an impression on even the most durable mattress. Rotating your mattress—or flipping it (but only if it’s designed to be flippable)—can slow down the process.
Rotate or flip your mattress about four times a year, or as often as recommended by the manufacturer. As always, be sure to check the recommendations and warranty beforehand.
Keep It Clean
Life can get messy, and a mattress protector can help protect your mattress from the inevitable coffee spill, pet dander, and much more. You can also clean your mattress regularly to keep it fresh and free of stains.
Mattress protectors and regular cleaning might not prevent a mattress from sagging, but they can keep it more comfortable for longer.
A Closer Look at Our Selections
In choosing our best mattresses that don’t sag, we emphasize two testing categories that determine how likely a mattress is to resist sagging: durability and edge support. Here’s a look at how our picks performed in the Mattress Advisor Sleep Lab:
|Mattress||AVERAGE SCORE (OUT OF 10) FOR DURABILITY AND EDGE SUPPORT|
|Brooklyn Aurora Luxe||8.0|
|Puffy Lux Hybrid||7.3|
Note: The testing categories we focus on in this chart don’t reflect overall performance. Depending on your needs and preferences, you might put more or less value on particular qualities.
No mattress shopper wants to buy a new bed only to experience sagging. While all mattresses will live through some wear and tear over time and nothing can be designed to last forever, we believe that the mattress options covered in this article offer some of the best choices for long term durability, support, and overall comfort.
Depending on your sleep style and sleep position, you are sure to find that one of these mattresses is right for you, allowing you to realize a return on your investment while also getting a great night’s sleep and waking up refreshed and ready for the day.
Why does my mattress sag?
Your mattress probably sags because the materials are worn out. Over time, comfort materials—including fluffy pillow tops or foam layers—develop lasting impressions where you lie. Sagging is inevitable, although high-quality materials take longer to form indentations than lower-quality materials.
While age is usually the cause of a sagging mattress, there are other potential reasons your bed might sag. For instance, softer mattresses sink in more than firmer beds, even when new. And the more body weight, the deeper the sagging. If you have a bigger body type, consider a firmer mattress for greater support and lift.
Finally, your mattress can sag when on a poor foundation. You want to ensure that you place your bed on a bed frame or foundation that fits the manufacturer’s recommendations. Old box springs and frames with slats spaced too far apart can cause your mattress to dip.
Do hybrid mattresses sag?
Any type of mattress can sag, although all-foam beds are more prone to early sagging than hybrid mattresses. This is because most hybrid beds have a layer of steel innerspring coils, a strong and durable material that bounces back, helping to minimize excess sinkage.
However, hybrid beds utilize various comfort materials along the surface that are prone to forming body impressions over years of use. Additionally, softer hybrid mattresses may not provide enough support for heavyweight folks, leading to sagging from day one.
If you want a hybrid bed that doesn’t sag, choose one that utilizes high-quality comfort materials. Excellent options for minimal sagging include latex foam and high-density memory foam.
