Mattresses are a major investment. After spending hard-earned money, people want to trust that theirs is going to last. That’s why it’s so discouraging when the mattress starts to sag.

How We Chose the Best Mattresses That Won’t Sag
Our team of Certified Sleep Science Coaches have reviewed more than 150 mattresses, using proprietary analysis and hands-on testing to establish easy-to-understand scores. In addition to an overall score, we measure subscores for support, edge support, cooling, motion transfer, durability, trial period and warranty.
Because a longer-lasting mattress is less likely to sag, we paid extra-close attention to the category of durability for this roundup. We considered about 30 mattresses for this roundup, and ultimately came up with a list of 10 that we’re confident won’t sag over time. All of the 10 beds on this list scored at least a 3.5 out of 5 or higher on durability.

Our Expert’s Take
If you’re a back or stomach sleeper who suffers from back pain, the Helix Dawn mattress could be a great choice. This bed feels a bit firmer than average beds, coming in at 7.5/10 on our firmness scale. This not only prevents it from sagging; it’s also a supportive option for heavier people! We expect the Helix Dawn mattress to have a long lifespan as well–at least 10 years.
What the testers say: “The Helix Dawn mattress has a balanced feel that’s both pressure-relieving and supportive. When I slept on my back and stomach, I felt very supported and comfortable. If you’re dealing with back pain, this bed may help you keep your spine in the proper alignment.” – Marten, Lead Reviewer
What We Love About the Helix Dawn
- This mattress is constructed with high-quality individually-wrapped coils and proprietary Helix Dynamic Foam, making it very durable and long-lasting.
- Back and stomach sleepers will enjoy plenty of spinal support and alignment. Its firm feel keeps hips elevated to prevent lower back pain.
- This bed’s coils and high-grade DuraDense polyfoam provide a bouncy and responsive feel. This construction makes it easy to move around on.
What to Keep in Mind About the Helix Dawn
- Side sleepers will find this mattress to be too firm against their shoulders and hips.
- People who prefer a softer mattress or a memory foam feel should explore other options. This bed is a good deal firmer than the industry-standard for medium firmness of 6.5/10. We ranked the Helix Dawn around a 7.5 out of 10 on the firmness scale.
Other User Reviews
On Helix’s website, the Helix Dawn has an average rating of 4.4 out of 5 stars from 1,225 published reviews. Five star reviews rave that the bed is not too firm and not too soft and that it fixed user’s back problems. Some of the negative reviews claimed that the bed was too soft for them or that the mattress’s texture was inconsistent or lumpy.

Our Expert’s Take
Latex is great if you want a mattress that won’t sag. The Nolah Natural is a latex hybrid mattress that is a great long-term investment. It features thick Talalay latex in its comfort layer which won’t break down the way some memory foam and polyfoam might. In addition to the Talalay latex, the mattress contains organic cotton, wool and other eco-friendly materials. This makes the Nolah Natural a great organic mattress that won’t sag.
What the testers say: “The Nolah Natural’s zoned support system keeps me feeling comfy and supported whenever I rest on my back and side. I also love the breathable latex foam–I don’t sink too far into the mattress, but I still get the pressure relief I need. This bed feels super breathable and cool, which is great because I tend to overheat at night.” – Elisa, Reviewer
What We Love About the Nolah Natural
- This mattress boasts several certifications guaranteeing its organic and sustainably-sourced materials. The Nolah Natural meets strict industry standards on responsible business practices and emissions requirements, which is a huge plus for eco-friendly shoppers.
- Its zoned coil support system provides extra support in the hip area and promotes spinal alignment in the lumbar area of your back.
- This bed’s innerspring support layer and breathable Talalay latex layer mean hot sleepers should not be overheating.
What to Keep in Mind About the Nolah Natural
- Stomach sleepers will find this mattress too soft to support their hips. This can lead to lower back pain over time.
- The mattress’s innerspring bouncy feel means it doesn’t isolate motion well. Couples might be disturbed by their partner shift positions while they are sleeping.
Other User Reviews
The Nolah Natural has an average rating of 4.7 out of 5 stars on the Nolah website. Many users praise how the Nolah Natural is constructed with high-quality materials and how their quality of sleep improved after purchasing the bed. Some reviewers didn’t see a dramatic difference in their sleep quality and still woke up with some aching and pain.

Our Expert’s Take
It’s called the Plank for a reason. This bed from Brooklyn Bedding comes with both a firm side and an extra-firm side. The former scored an 8/10 on our mattress firmness scale, and the latter scored a 9/10. To give you some context, a 1/10 would be like lying on a giant marshmallow and a 10/10 would be like lying on a board. So the Plank Firm is for folks who want a firm and supportive mattress that will keep them lifted and help their spine stay in a neutral alignment. And because this bed is so firm, it won’t dip or sag as time goes on!
What the testers say: “Both sides of the Plank have a firm foam feel. I didn’t sink into the top layers very much, so it was very easy for me to move around on top of this bed. As a heavier person, the extra firm side offered plenty of support whenever I rested on my back and stomach.” —Marten, Lead Reviewer
What We Love About the Plank Firm
- This flippable bed comes with two firmness options in one. We ranked the firm side of the Plank Firm around an 8/10 on the firmness scale, and we ranked the extra-firm side close to 9/10.
- Both sides are great options for average-weight and heavyweight stomach sleepers. They keep the hips elevated and aligned with the spine while sleeping.
- The firm side provides back sleepers with adequate pressure relief around the hips.
What to Keep in Mind About the Plank Firm
- Both sides are much firmer than the industry standard for medium-firmness. If you are not looking for an extra-firm mattress, consider options closer to the 6.5/10 standard.
- Side sleepers will not find enough pressure relief on either side of the mattress. There’s no “give” from the mattress, so side sleepers will experience a lot of pressure around the shoulders and hips.
Other User Reviews
The Plank Firm mattress boasts a 4.8/5 user rating of 2,670 reviews on the Brooklyn Bedding website. Sleepers looking for an extra-firm bed agreed this was a great investment to improve their sleep quality. For those who prefer the extra-firm feel, they claimed this mattress was great for back pain. Other reviews were mixed whether the mattress was too firm or too soft for their liking. Keep in mind though, firmness is subjective and will change from person to person.

Our Expert’s Take
WinkBeds is known for creating luxurious mattresses with an innerspring feel. With the WinkBeds Plus, they took this support even further by designing a mattress specifically for heavy people. Heavy sleepers over 230 lb should feel lifted by the Plus’ exceptionally tall layer of coils. That means it’s extremely unlikely to sag, even under extra weight. This mattress also contains high-quality features, such as a cooling Tencel cover and gel-infused Euro pillow top.
What the testers say: “As a larger person, I love the WinkBed Plus’ durable coil system. I don’t feel like I’m sinking into the mattress, and it’s supportive enough for back and side sleeping. I also enjoy the luxurious features. The Tencel cover feels cool-to-the-touch, and the reinforced edge system gives the bed excellent edge support.” —Marten, Lead Reviewer
What We Love About the WinkBeds Plus
- Heavyweight back and stomach sleepers should enjoy great spinal support on this bed. Its highly supportive and durable coil system will keep sleepers from sinking too far into the mattress.
- Its zoned support layer makes the mattress slightly firmer near the center. This means back and stomach sleepers’ hips will feel fully supported while they sleep.
- Several design features make this bed a great option for hot sleepers. Its breathable Tencel fabric cover and innerspring support layer allows plenty of airflow throughout the mattress.
What to Keep in Mind About the WinkBeds Plus
- Generally, lightweight sleepers will find this mattress to be too firm. A softer mattress could provide better pressure relief and body contouring to lightweight sleepers.
- Because this mattress is firmer than the industry standard, average-weight and heavyweight side sleepers might experience uncomfortable pressure around the shoulders and hips.
- Sleepers who prefer a memory foam feel won’t be a fan of the Winkbed Plus’ bouncy innerspring feel.
Other User Reviews
There are over 8,000 reviews on WinkBed’s website, and the WinkBed Plus has achieved an impressive average 4.8 out of 5 stars. Five star reviews praised how the mattress did not sleep hot and how comfortable it was. The Luxury Firm model did not meet some sleeper’s expectations of firmness, most claiming it was too firm for their liking.

Our Expert’s Take
Softer mattresses aren’t always a great option if you want something that won’t sag. Many include foams (which are great for pressure relief but not always for durability), and these beds are some of the first to wear down. The ideal solution? The Bear Elite Hybrid. First off, it contains individually-wrapped coils that should last for a number of years without sagging. Second, the top foam layers are high-quality and shouldn’t lose their shape too quickly. Being a hybrid, the Bear Elite Hybrid has a balance of comfort and support and should work for most sleeping positions, depending on which firmness you choose.
What the testers say: “The Bear Elite Hybrid is a high-quality mattress made with luxurious materials. Sleeping on it felt like being on a nice hotel mattress. It’s also thicker than traditional mattresses, so we expect it to have a long lifespan. The Bear Elite Hybrid should last at least 10 years.” —Elisa, Reviewer
What We Love About the Bear Elite Hybrid
- This mattress comes in three firmness options. We reviewed the Luxury Firm option which is ideal for combination sleepers, as it works for both back and side sleepers, who should feel well-supported.
- This bed is a great option for sleepers with back pain. Its bouncy coils create plenty of lumbar support, even for sleepers around 230 lb.
- It is constructed with cooling materials throughout its layers. The Bear Elite Hybrid is made from copper-infused memory foam and zoned comfort foam designed to promote airflow.
What to Keep in Mind About the Bear Elite Hybrid
- The Bear Elite Hybrid is a high-end long-term investment. It could be too pricey for those on a strict budget.
- Heavyweight sleepers close to or over 300 lb might find this bed not supportive enough.
Other User Reviews
The Bear Elite Hybrid mattress received 266 reviews on the Bear website with an average score of 4.5/5. Top reviews rave about how users don’t wake up with back pain and that the Elite Hybrid is an upgrade from their previous mattress. Combination sleepers were highly satisfied and could sleep well without aching pain. But other reviewers did not find this mattress as comfortable or as firm as they expected.

Our Expert’s Take
The Saatva HD was designed with larger sleepers in mind. We named it one of the best mattresses for heavy people! It has a plush pillow top followed by a layer of zoned latex foam. This means it feels firmer in some areas and softer in others. For support, there’s a layer of thick foam and 12.5 gauge tempered steel coils. In addition to creating excellent edge support, these springs give folks a luxurious sleep experience.
What the testers say: “As a 6’7” person, I love the Saatva HD’s supportive coils and comfy pillow top. While lying on my back, I feel that extra lumbar support from the coils and latex layer. My hips also press in just the right amount for this sleeping position. And thanks to the breathable latex foam, I don’t overheat at night!” — Marten, Lead Reviewer
What We Love About the Saatva HD
- This bed is designed to provide heavyweight sleepers with enough pressure relief and lumbar support. This makes for a great option for heavyweight sleepers of all sleep positions.
- Its ventilated latex comfort layer is naturally cooling, and its steel coil support layer promotes airflow throughout the mattress.
- This mattress’s durable materials make it a great long-term investment. You can expect it to last at least 10 years without sagging.
What to Keep in Mind About the Saatva HD
- Its luxurious materials come with a price tag that might be out of range for shoppers on a budget.
- Most average and lightweight sleepers will find the Saatva HD to be too firm. They should check out other softer mattress options from Saatva, like the Saatva Classic.
Other User Reviews
The Saatva HD has a nearly perfect 4.9/5 star rating on the Saatva website. Users were impressed by the high-quality buying and white glove delivery experience. Heavier sleepers found this mattress to be comfortable and sturdy enough to feel supported while sleeping.

Our Expert’s Take
When it comes to sleeping positions, having a mattress that doesn’t sag is especially important for stomach sleepers. If the mattress dips too much, it can cause their hips to bow and fall out of alignment with their shoulders. Luckily, the Birch mattress is made from materials that should keep stomach sleepers lifted and healthily aligned. Its comfort layers are made of latex foam—a material known for its natural durability and responsiveness. At the bottom of the mattress, a layer of individually wrapped coils adds to the mattress’ overall support.
What the testers say: “When I sleep on my back and stomach, I feel a great balance of comfort and support. The latex layers cushion my joints but prevent me from sinking too far into the foam. And thanks to the breathable wool and latex, the Birch mattress doesn’t overheat at night.” — Marten, Lead Reviewer
What We Love About the Birch
- This all-natural mattress is free of harmful chemicals, durable and eco-friendly. It is certified to be sustainably-sourced and meet strict emissions standards.
- It’s a great fit for average and lightweight stomach sleepers. The firmness level prevents hips from dipping too far into the top layer, which helps keep the body in alignment.
- The Birch is a hybrid mattress, and its coils promote airflow through the mattress, making it very breathable.
What to Keep in Mind About the Birch
- Because the Birch is made with high-quality, environmentally-friendly materials, it is not as affordable as a non-organic mattress.
- Average and heavyweight side sleepers may find that this mattress adds too much pressure to their shoulders and hips. These sleepers might find more comfort with Birch’s pillow-top mattress topper, which they can add for an additional fee.
Other User Reviews
Over 1,800 reviews rated the Birch mattress an average score of 4.7 out of 5. Users mentioned being able to rest easy knowing that the Birch mattress is made with no hazardous chemicals. Most people love how this bed is not too firm and not too soft, but some people wished the mattress was a bit firmer.

Our Expert’s Take
When you’re shopping for a mattress that won’t sag, you might find yourself paying more for the materials. But if you want a durable mattress that won’t cost you an arm and a leg, check out the Brooklyn Bedding Signature Hybrid mattress. Unlike many mattress brands, Brooklyn Bedding owns their own factory, allowing them to pass the savings onto the consumer.
What the testers say: “I love resting on the Brooklyn Bedding Signature Hybrid’s plush pillow top. The top layers cushion my joints, and the coils underneath offer the right amount of support. I felt comfortable while back and side sleeping, and I didn’t overheat on this mattress.” – Marten, Lead Reviewer
What We Love About the Brooklyn Bedding Signature
- This mattress comes with more size options than the industry standard. It is also sold at affordable prices for shoppers on a budget.
- The mattress does a good job of regulating body temperature and dissipating heat. Its main comfort layer is made with proprietary TitanFlex foam to promote cooling.
- It offers comfort and support to combination sleepers, especially those who are average or lightweight.
What to Keep in Mind About the Brooklyn Bedding Signature
- This bed is not the best fit for heavy people. They’ll want to look for a more supportive mattress, like the Titan.
- As an innerspring mattress, it doesn’t absorb motion well. For couples who share a bed together, this may be an issue.
Other User Reviews
There are over 10,000 reviews on Brooklyn Bedding’s website, and the Signature Hybrid has achieved an average 4.7 out of 5 stars. Many users purchased the Signature Hybrid for their RVs and could sleep comfortably while on the road. Combination sleepers also praised the mattress for being the right level of firmness for their preferred positions.

Our Expert’s Take
The DreamCloud is a hybrid mattress that is built with individually-wrapped coils, gel-infused cooling foam, and a cashmere-blend cover. It’s responsive and easy to move around on which could work well for elderly combination sleepers, and the great edge support can ensure that seniors don’t roll off of the bed, even when sleeping near the end of it.
What the testers say: “The DreamCloud offers a balance of comfort and support, and because of that, I felt great back sleeping on it. My hips sank in just the right amount, keeping my spine aligned, and the layer of coils helped to keep me supported.” – Marten, Lead Reviewer
What We Love About the DreamCloud
- This bed is ideal for shoppers who are looking for a hybrid mattress for a value price.
- The DreamCloud is built with a breathable cashmere-blend cover and gel-infused memory foam to prevent hot sleepers from overheating.
- Its soft, quilted cover and innerspring support layer make this mattress feel bouncy and responsive. You’ll find that this mattress is easy to move around on.
What to Keep in Mind About the DreamCloud
- It may not provide enough pressure relief to side sleepers, especially those who are average or heavyweight.
- Sleepers closer to 300 lb might not find the support they need in the shoulder and hip region. We recommend these sleepers opt for a mattress for heavy people.

Our Expert’s Take
If you want a mattress that won’t sag too quickly, a firm mattress is a good place to start. The Titan Plus is made for heavy people and is one of the firmest mattresses on this list. Our average weight reviewer ranked the mattress at a 9/10 for firmness, but with that said, it’ll probably feel a bit softer for heavier sleepers. The Titan Plus features durable materials designed to withstand and support heavier weights. Whether you are heavier or not, this firm mattress should give you a great amount of firmness and should last you a long time.
What the testers say: “I’m a heavier person and am 6’7”, so the Titan Plus was very supportive for me. I got some good support back sleeping, but for some, the hips may not sink into the mattress enough to be comfortable. Stomach sleeping felt the best on this mattress though, since the firm feel let my hips sink and my spine get the right support.” – Marten, Lead Reviewer
What We Love About the Titan Plus
- Heavyweight back and stomach sleepers will feel enough comfort and support from this bed, especially in the hip area. Its heavy duty TitanCaliber coils keep sleepers over 300 lb from sinking too far into the mattress.
- It’s priced lower than many other beds made for larger people.
- Its gel-infused memory foam cover provides a touch of that slow-moving feel on top as well as cooling comfort.
What to Keep in Mind About the Titan Plus
- This mattress is much firmer than the industry standard of medium-firmness of 6.5/10. This makes it too firm for average-weight side sleepers and practically all lightweight sleepers.
- Some heavyweight side sleepers might find this mattress doesn’t provide enough pressure relief.
Other User Reviews
On Brooklyn Bedding’s website, the Titan Plus has an average rating of 4.7 out of 5 stars from 2,441 published reviews. Heavier sleepers were pleased with how sturdy and supportive the mattress was in all sleeping positions. A couple reviews across the board said adding a mattress topper further improved their sleep quality on the Titan Plus.

What Should Someone Consider When Finding A Mattress That Won’t Sag?
- What is the density of the foam found in the mattress? Mattresses often sag because there’s a layer of low-density foam somewhere in the construction. So if someone wants a foam mattress that won’t sag, they should pay close attention to the foam density. If someone chooses a mattress that is 2.5- or 3-lb foam, it might start to sag. But if they pick a mattress with 4- or 5-lb density foam, this should help the mattress last longer.
- What type of foam is featured in the mattress? If someone wants a mattress that won’t sag, latex foam is going to be particularly good because it’s responsive, bouncy, and durable. This natural product can handle heavier weights without sagging.
- Does the mattress feature coils in its construction? If someone wants a mattress that isn’t going to sag, they should take a look at something with innerspring coils because they add an extra level of support and durability. The coils will help support heavier weights while also fighting significant sagging in the mattress.
- Make sure you get the right support system. Getting the right support can keep your mattress from sagging too quickly. Your mattress could require a special foundation or box spring.
- How often should you replace your mattress? Think about how long the mattress is going to last and when it might be time to switch up.

How To Tell If A Mattress Is Sagging
Impressions
Note that there’s a difference between the natural body impressions of a bed and a mattress that’s truly sagging. Body impressions are usually a series of small dips. Sagging results in one long dip across the bed, almost resembling a smile that runs the length of the mattress.
Dip
If you think your mattress is sagging, measure the dip. If it’s less than two inches deep, then you’re fine. But if it’s more than two inches deep, that means your bed is sagging.
How To Fix A Sagging Mattress
Find the Proper Base
Replace the sleep foundation, and make sure your new foundation — whether a platform bed, slats, or something else — is compatible with your specific mattress. If you use slats, make sure they’re evenly spaced out.
Use Pillows
Strategically add pillows around your back, hips, and legs. This is more of a temporary solution, but it will somewhat replace the support that’s been lost in the sagging mattress.
Add a Mattress Topper
This will thicken the bed and provide more contouring and support. See our list of best mattress toppers if you’re in need of suggestions!
Turn Around Your Mattress
Turn your mattress around so that the head is now the foot and vice versa. This will redistribute your body weight and help keep the mattress from sagging further.
What Causes A Mattress To Sag
The reasons are relatively simple. First, a mattress may sag as a result of simple wear and tear on a bed. The more common reason is that the mattress isn’t properly constructed for durability. That’s why it’s so important to get a mattress that you know will last you years and years.

FAQs
Do memory foam mattresses sag?
Low-quality memory foam mattresses have a tendency to sag. To avoid this, make sure you find a bed made with high-density foam. These beds will last much longer (about seven to 10 years). If you’re particularly worried about a sagging mattress, opt for a hybrid model made with springs and memory foam. The supportive coils underneath should keep the mattress in good condition for many years.
Can a bed frame cause a mattress to sag?
Yes. If your bed frame isn’t supportive enough, your mattress could sag. The same goes for box springs. If your current box spring can’t support your mattress’s weight, the bed might dip and sag.
Can you fix a sagging mattress?
While it’s more or less impossible to permanently fix a sagging mattress, there are temporary solutions such as replacing your sleep foundation, rotating your bed, adding more pillows to specific areas of your body and adding a mattress topper. You can also help prevent sagging by flipping your mattress (if it is flippable), or if it’s not flippable (most beds these days aren’t) by rotating it 180 degrees every six months or so.
Can a sagging mattress cause back pain?
Yes. Because the bed is no longer evenly supportive, a sagging mattress can cause pain and stiffness, and throw your spine out of its neutral alignment. You wan’t your mattress surface to be flat and even, as that is how it will best support a straight neutral spinal alignment, which is key to preventing back pain.
How much should a mattress sag?
A mattress that sags two inches or less is perfectly normal. If it’s sagging more than two inches, then it’s time to think about a solution.
