In This Roundup
Sagging mattresses can cause lower back pain and discomfort. Let’s review the best mattresses that will stay supportive even after years of use.
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.
The Best Mattresses that Won’t Sag : Our Experts Picks
Nectar – Best Mattress For Side Sleepers 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. Our rigorous testing and reporting process has helped over 4,500 readers purchase the best mattress for their needs.
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.
How We Chose the Best Mattresses That Won’t Sag
Mattress Type
A solid support system is key if you want a mattress that won’t sag, and mattress type will determine the primary support layer you rest upon. We choose several hybrid mattresses, or beds that have springs in individually wrapped pockets, providing both support and flexibility, and reducing the chance of sagging. In all-foam mattresses, we looked for beds with multiple layers of high-density foam or latex.
Mattress Thickness
A thicker mattress is generally less prone to sagging. A thicker mattress will also typically ensure a mattress won’t sag under heavier body weights, as well. Finally, a thicker mattress tends to be at least a medium-firm to firm, and while firmness doesn’t 1:1 translate to better support, firmer mattresses do tend to maintain their structure better over time compared to a softer mattress. Each mattress we choose is at least 10″ in thickness, with many surpassing thicknesses of 13″.
Warranty and Sleep Trial
We choose beds with lengthier sleep trial periods, letting you test the mattress in your own home for an extended period to see if it sags. The beds we choose have a minimum of 120 night sleep trials, although some extend up to a year. If the mattress begins sagging or doesn’t offer the right support during the trial period, you can return the bed for a refund or exchange. We also choose mattresses with longer warranty periods (15 years or more), which can be a good sign of mattress durability.

Couples
This mattress isolates motion well, which means couples shouldn’t feel movement come over to their side of the bed.
Side Sleepers
It offers great pressure relief for side sleepers under 230 lbs.
Back Sleepers
The Nectar mattress offers plenty of support for most back sleepers under 230 lbs.
Pros of the Nectar Mattress
This mattress has a slow-moving feel. If you like mattresses that contour to your body, this could be a great option.
The Nectar mattress isolates motion well, which is helpful for people who share a bed with a partner or a pet.
It offers plenty of pressure relief for side sleepers who weigh less than 230 lb.
Cons of the Nectar Mattress
Even though it has cooling gel-infused foam, it’s not the best mattress for hot sleepers.
It’s not supportive enough for most stomach sleepers. In this position, you may feel your hips sink out of alignment, which can lead to lower back pain.
Because it’s an all-foam bed-in-a-box mattress, it has a 48-hour off-gassing period. You’ll need to let the mattress air out for two days before sleeping on it.

The Nectar is an affordable all-foam mattress that offers lots of pressure relief and body contouring. It works well for most side sleepers, because it helps cushion shoulders and hips. It is also a good option for couples, because it isolates motion well. However, the Nectar mattress isn’t supportive enough for most stomach sleepers and heavyweight people. If you tend to sleep hot at night, you may want to look for a mattress with more cooling features. Learn more in our Nectar mattress video review.

Our Expert’s Take
Side sleepers need a mattress that can offer a safe blend of pressure relief and cushioning for their knees and shoulders while ensuring their spine remains supported in a safe resting position throughout the night. The Nectar Original is an all-foam bed with a medium-firm (6.5/10) feel that testers found to be a go-to for most side sleepers after putting it to the test. Average weight (under 230 lbs) and lightweight (under 130 lbs) side sleepers can expect excellent support on the Nectar. However, heavier side sleepers (230 lbs and up) may want a firmer mattress, as our heavier tester found himself experiencing some problematic sinkage when resting on the Nectar on his side. Furthermore, back sleepers of all sizes should find plenty of foam-based comfort and spinal support on the Nectar Original.
What We Love About the Nectar
The Nectar offers a slightly firmer (6.5/10) feel than some side sleepers may be used to. However, side sleepers can still experience this level of firmer joint and spine support due to the bed’s design, and still get the pressure relief and cushioning they need.
Despite being an all-foam mattress, the treated cooling foam technology Nectar uses in its design efficiently dissipates body heat and maintains a super cool and comfortable sleeping surface, making the bed great for hot sleepers.
Nectar’s excellent edge support and motion isolation make it a great mattress for couples sharing the bed. Its surface provides consistent edge-to-edge support, allowing both sleepers to cozy up on its edges without experiencing posture-disrupting sinkage or sagging.
What to Keep in Mind About the Nectar
According to tests, except for lightweight stomach sleepers, most stomach sleepers will find the Nectar too soft and not provide enough pressure relief and support.
While the Nectar is excellent for lightweight and average-weight side sleepers, heavier (230 lbs and up) side sleepers should consider a firmer or innerspring mattress. Heavyweight side sleepers should consider the Titan Plus.
What Customers Say
On Nectar’s official website, its classic mattress has thousands of reviews and an average rating of 4.7/5. One couple attested to reducing their lower back pain after using the Nectar for some time, stating, “My wife and I’s sleep has changed so much since purchasing our Nectar. Both of us have noticed much-increased levels of rest and are now experiencing less pain in certain areas of our bodies.”

Cons
Stomach sleepers probably won’t find this bed supportive enough to keep their spine in proper alignment.

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.
What We Love About the Helix Midnight Luxe
The Helix Midnight Luxe has an incredibly sturdy perimeter. In fact, we awarded it a perfect score on our edge support test. What this means is that if you like to sleep or sit along the edges of your bed you likely won’t experience any sagging or dipping under your weight.
This mattress isolates motion quite well. When we tested the mattress, we weren’t able to feel much movement from one side of the bed to the other. This is good news for couples, particularly if one or both of you are light sleepers.
Back sleepers, regardless of body type, should appreciate the medium firmness of the Helix Midnight Luxe. Your shoulders and hips will sink below the surface a bit, but not so much that your spine is thrown out of alignment.
What to Keep in Mind About the Helix Midnight Luxe
We don’t recommend this mattress for stomach sleepers. It’s too soft for average- and heavyweight stomach sleepers to get the support they need. If you weigh 130 lbs or less, you may be comfortable on the Helix Midnight Luxe, but it still might not be a perfect fit. We suggest you check out our article on the best mattresses for stomach sleepers. For a specific bed for stomach sleepers that won’t sag checkout the Birch.
What Customers Say
The Helix Midnight Luxe has an average rating of 4.4 out of 5 based on 5,887 customer reviews on the company website. Positive reviews highlight the bed’s middle-of-the-road firmness, as well as its ability to accommodate different types of sleepers. As for the negative reviews, they tend to revolve around experiences with the customer service team.

It has a flippable design, so you can easily change its firmness level by turning the mattress over.
It’s the firmest mattress we have tested, so if you need a lot of spinal support, this is a good option.
It works well for stomach sleepers because it helps keep hips elevated and in the correct alignment.
Cons of the Plank Firm
This mattress is too firm for most side sleepers.
Because it’s made entirely out of foam, it tends to trap body heat.

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!
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 may provide 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, you can find some great options on our best medium-firm mattress review.
Side sleepers may 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. Side sleepers looking for a bed that won’t sag should check out the Nectar.
What Customers Say
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 was one of the best mattresses 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.

Shoppers looking for a long-lasting mattress will love the Saatva. It feature high-density foam and durable coils that should ensure it lasts for over 10 years.

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.
What We Love About the Saatva Classic
Multiple firmness options mean the Saatva can cater to a wide range of people. Whether you’re a lightweight side sleeper and need something with a little more cushioning, or you’re a heavyweight stomach sleeper and need a mattress that will support your hips, the Saatva should have you covered.
We tested the medium-firm version of the Saatva—what they call the Luxury Firm. Our mattress testers found it performed exceptionally well for lightweight stomach sleepers and average-weight back sleepers.
What to Keep in Mind About the Saatva Classic
This mattress is on the expensive side, as a queen will cost you just over $2,000. If you’re interested in something more affordable, consider the Brooklyn Bedding Signature Hybrid.
The Saatva earned a disappointing 3/5 on our motion transfer test. Our testers were easily able to feel one another’s movements as they shared the bed, meaning this might not be the best option for couples, particularly those made up of light sleepers. Instead, we would suggest the Helix Midnight Luxe.
What Customers Say
Based on 3,436 customer reviews on the Saatva website, this mattress has an average rating of 4.8 out of 5. Compared to other mattresses, 66 5-star reviewers were happy to find that the Saatva didn’t show any signs of sagging after some time. That said, there is one 1-star review that mentions the mattress began sagging after one year.

Our Expert’s Take
WinkBeds is known for creating some of the best luxury 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.
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 help keep sleepers from potentially 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 likely 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 probably 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 probably won’t be a fan of the Winkbed Plus’ bouncy innerspring feel. If you’re seeking a true memory foam feel, check out our best memory foam mattresses. I’m particularly fond of the Nectar Classic Memory Foam.
What Customers Say
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
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 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 might find this mattress too soft to support their hips. Consider looking into our best mattress for stomach sleepers review to find a better fit for you, with my specific recommendation being the Birch.
The mattress’s innerspring bouncy feel means it doesn’t isolate motion well. Couples might be disturbed by their partner shifting positions while they are sleeping. Couples should check out our best mattresses for couples page instead. For couples looking for superior motion isolation, I’d point you to the Nectar Luxe.
What Customers Say
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.

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.

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 potential comfort and support to combination sleepers, especially those who are average or lightweight.

This bed might not be the best fit for heavy people. They’ll likely want to look for a more supportive mattress like the Titan Plus.
As an innerspring mattress, it doesn’t absorb motion well. For couples who share a bed together, this may be an issue.
What Customers Say
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 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.
What We Love About the Titan Plus
Heavyweight back and stomach sleepers might 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. The Bear Elite Hybrid could be a great fit for these groups.
Some heavyweight side sleepers might find this mattress doesn’t provide enough pressure relief.
What Customers Say
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.

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.
What We Love About the Bear Elite Hybrid
This mattress comes in three firmness options. We reviewed the Luxury Firm option which is likely 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. If you’re on a tighter budget, get more information on the Brooklyn Bedding Signature Hybrid.
Heavyweight sleepers close to or over 300 lb might find this bed not supportive enough. If you are a heavy sleepers, consider our best mattress for heavy people review to find a mattress that can support your needs.
What Customers Say
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
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 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 potentially great fit for average and lightweight stomach sleepers. The firmness level may help prevent 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. However, if synthetic materials aren’t a deal breaker for you, the Brooklyn Bedding Signature Hybrid is an affordable bed that won’t sag.
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.
What Customers Say
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.
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-lbs foam, it might start to sag. But if they pick a mattress with 4- or 5-lbs density foam, this should help the mattress last longer.
What type of foam is featured in the mattress?
Most commonly, you’ll see memory foam used in mattresses. If you’re someone who wants a mattress that won’t sag for many years, look into latex foam. Natural latex foam (rather than synthetic latex) is going to be particularly good for longevity because it’s responsive, bouncy, and durable. This 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?
Over time, even the sturdiest coils and densest memory foam will weaken and lose shape. Think about how long the mattress should last based on its construction and feel, giving you a ballpark to know when it might be time to switch it up. But don’t fret — there are also several clear-cut signs that a mattress needs to be replaced.
What are the signs that it’s time to replace my mattress?
About those signs: First, there’s the obvious one, and the reason you’re reading this page — sagging. If the indentations made by your body persist, and never bounce back, you’re mattress is due for replacement. A squeaky mattress is another sign of weakened coils, and a bad-smelling mattress could be a sign that humidity has compromised your mattress (something a mattress protector can help protect from). You’ll also want to listen to your own body: If you’re waking up with sore joints, for example, a new mattress may be in order.
How To Tell If A Mattress Is Sagging
Impressions in the Mattress
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 Your Mattress Around
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.
Are these steps not solving your sagging mattress issues, read our mattress experts guidance on steps you can take to fix a sagging mattress.
What Causes A Mattress To Sag
A mattress may sag due to simple wear and tear on a bed. Nightly use can lead to an indention in where you typically sleep because materials begin to break down with repeated use. This is particularly true for mattresses that use lesser-quality materials. You may first notice sagging around your center of gravity, which is usually the heaviest part of your body and puts the most strain on the construction. However, mattresses oftentimes sag because they aren’t properly constructed for longevity. That’s why getting a mattress that you know will last you years and years is so important.
Final Thoughts
Here’s a recap of our top picks for the best mattresses that won’t 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.
