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. (Pro tip: If you currently have a sagging mattress, check your mattress warranty to see if sagging is covered.) However, not all mattresses will give up so quickly. After testing and analyzing numerous beds, I’ve found the best 10 mattresses that won’t sag. These beds are not only durable, but also high-quality!
Our Top Picks
The best mattresses that won’t sag are:
- Helix Plus – Best Firm Mattress That Won’t Sag

Video Review: Best Mattresses that Won’t Sag
How We Chose Our Products
Our team of sleep specialists 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. All of the 10 beds on this list scored at least a 3.5 out of 5 or higher on durability.

If you want a mattress that won’t sag too quickly, a firm mattress is a good place to start. The Helix Plus is made for heavy people and is one of the firmest mattresses on this list. We ranked the mattress at a 7.5/10 for firmness, which is definitely firmer-than-average. The Helix 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 support and should last for a number of years.
What Makes The Helix Plus Stand Out?
- The Helix Plus is one of the best mattresses for heavy people.
- The mattress is a good fit if you like sleeping on top of your mattress.
- The Helix Plus is a great long-term investment.

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 Makes The Saatva HD Stand Out?
- This mattress has a firm, hybrid feel that’s best suited for heavier back, side, and stomach sleepers. However, some average-weight stomach sleepers may also find that it’s a good match.
- The zoned latex layer and durable steel coils create a great balance of comfort and support.
- When you shop with Saatva, the company offers free white glove delivery and a 180-night sleep trial period.

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 Makes The Brooklyn Bedding Stand Out?
- You can expect the Signature Hybrid to last for a number of years. This is because it features TitanFlex and Energex foam, as well as Ascension Coils (all durable materials).
- The Brooklyn Bedding comes in three different firmness levels, allowing you to find the perfect fit for you.
- The mattress is breathable and a good fit for hot sleepers.

If someone wants a mattress that won’t sag, they want to make sure it contains high-quality and high-density materials that won’t break down anytime soon. The DreamCloud easily meets this criteria with supportive coils and multiple layers of high-density foam that should stand up to years of use.
What Makes The DreamCloud Stand Out?
- This durable hybrid mattress offers an excellent balance of comfort and support. Back sleepers should feel their hips sinking into the plush pillow-top while the coils support them.
- Stomach sleepers should also be comfortable.
- The mattress offers a luxury look and feel that should remind people of sleeping in a hotel.

When many people shop for a soft memory foam mattress, they fear that it will sag after only a few short years. While the Nectar is a soft, comfortable memory foam mattress, shoppers can rest assured that it will hold up for quite some time. That’s because the Nectar features high-density foams in its construction.
What Makes The Nectar Stand Out?
- The bed has gel-infused memory foam, Hi Core memory foam, and base support foam, all of which should stand up to many years of constant use.
- The top memory foam layers should provide excellent pressure relief and contouring for side sleepers and back sleepers.
- Currently priced at under $1,000, the Nectar is one of the best value mattresses out there.

If you’re looking for durable mattress that’s soft enough to relieve those pressure points, the Leesa is an excellent choice. Its thick and responsive foam layer, as well as its durable foam foundation, contribute to its strength and support. However, it’s also pressure-relieving due to its proprietary slow-moving memory foam and plushy twill fabric cover. You should expect this comfortable mattress to last between seven and 10 years.
What Makes Leesa Stand Out?
- Sleepers in most sleeping positions, especially back sleepers and side sleepers who prefer a medium-firm feel, should be happy on the Leesa.
- Leesa’s all-foam construction provides great pressure relief without making you feel like you’re stuck in the mattress.
- Hot sleepers shouldn’t have to worry about waking up feeling clammy and dehydrated in the middle of the night.

Hybrid mattresses are usually a great option if you want something that won’t sag. One of our favorites it the Bear 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-density and shouldn’t lose their shape too quickly. Being a hybrid, the Bear Hybrid has a balance of comfort and support and should work for all three sleeping positions.
What Makes The Bear Hybrid Stand Out?
- The Bear Hybrid is one of the best mattresses under $2,000.
- This mattress is breathable and is a good cooling option.
- The Bear Hybrid is responsive and makes moving around very easy.

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 Makes The Nolah Natural Stand Out?
- The Nolah Natural features organic materials that will keep you sleeping cool all night.
It is a bouncy mattress that makes it very easy to move around and change positions.
The Nolah Natural is zoned, making it firmer toward the center, and a great fit for people with back pain.

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 out of 10 on our mattress firmness scale, and the latter scored a 9 out of 10. To give you some context, a 1 would be like lying on a giant marshmallow and a 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.
What Makes The Plank Firm Stand Out?
- Despite being one of the firmest mattresses out there, the Plank is made entirely of foam.
- Due to its firmness, this mattress is going to appeal most to stomach sleepers and back sleepers who prefer an extra-firm feel.
- For an additional charge, you can outfit the mattress with a cooling panel that should keep you from sleeping too hot.

Marten’s Take
Marten is our Director of Content, and he has a much different body type than me (he’s 6’7″ and weighs about 230 lb while I am 5’9″ and weigh 160 lbs). Here’s what he thought about these mattresses:
I reviewed the WinkBed Plus, which is made specifically for larger people like me. It’s extremely supportive and durable because there are high-density foams on top and particularly high-grade coils beneath that shouldn’t sag.
The Saatva HD is a fantastic choice for heavier sleepers who sleep in any position; it’s a great fit whether I am on my back, side, or stomach.
It seems Marten thought all 10 mattresses could be a good fit for him. This isn’t surprising, given that these are all very durable mattresses, and durability is usually accompanied by a decent amount of 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 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.
RELATED: How Often Should You Rotate Your Mattress?
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.

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 7–10 years). If you're especially 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.
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.
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.
