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 has reviewed more than 600 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.
![Latex mattress testing in our studio](https://www.mattressclarity.com/wp-content/uploads/2023/04/mattress-testing-09.jpg)
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
A hybrid construction goes a long way in improving the durability of a mattress, and for our money the Helix Midnight Luxe is one of the best hybrids out there. Made with a plush pillow top, comfort layers of responsive, cooling foam, and two support layers—one made up of individually-wrapped coils, and the other of dense foam—the Helix Midnight Luxe is very robust. We gave it a perfect score on our durability test, indicating a mattress that can maintain its structure for years to come.

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 people who are heavier in weight. Heavy sleepers over 230 lbs should feel lifted by the Plus’ exceptionally tall layer of coils. That means it’s 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.

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.

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 tend to be 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.

Our Expert’s Take
Innerspring coils are a commonly used material in making a mattress durable and supportive. The Saatva features two sets of steel coils, making this a very durable mattress that is unlikely to sag. Plus, the additional layer of coils makes for a very supportive mattress across the entire surface, so you shouldn’t have to worry about the edges of the bed dipping under your weight if you sleep along the perimeter. That said, if you’re a heavyweight person then you may want to opt for the Firm version of the Saatva, as it should do a better job of maintaining its structural integrity under your weight.

Our Expert’s Take
The Titan Plus was designed with larger sleepers (over 230 lbs) in mind. In fact, we named it one of the best mattresses for heavy people! The elements of its construction that make it sag-resistant also contribute to its compatibility with heavier people. The industrial coils provide support throughout the entire mattress, so heavier parts of your body won’t sink in more than they’re supposed to. Directly under the coil layer is a base of dense foam that holds up very well under weights up to and over 300 lbs.

If you want a mattress that won’t sag too quickly, a firm mattress is a probably good place to start. The Emma Hybrid Comfort is made for heavy people and is one of the firmest mattresses on this list. Our average weight reviewer ranked the mattress at an 8/10 for firmness, but with that said, it’ll probably feel a bit softer for heavier sleepers. The Emma Hybrid Comfort 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.

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 likely won’t dip or sag as time goes on!

When it comes to sleeping positions, having a mattress that doesn’t sag can be especially important for some stomach sleepers. If the mattress dips too much, it may 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 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 may 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 likely fine. But if it’s more than two inches deep, that means your bed is probably 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 can somewhat help 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 could 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?
Possibly. 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 may want your mattress surface to be flat and even, as this can help support spine alignment.
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.
