Written by Julia Forbes, Lead Product Tester
When it comes to a good night’s sleep, what could be worse than a mattress that sags? A sagging mattress can throw your spine and posture out of whack, leading to issues like discomfort, pain, and overall poor sleep. If you’ve noticed a stubborn indent in the middle of your mattress, it might be time for a new bed.
A mattress can sag for many reasons, but the most common culprits are poor construction or an inability to properly distribute your weight. Luckily, not all mattresses are created equal, and not all sag—at least, not as quickly. I’m here to help you find those lucky few.
Plenty of things go into ensuring a mattress won’t sag, but we’ve gathered a list of the top mattresses we think won’t let you down.
The best mattress that won’t sag should boast a strong support system that remains steady to the edge of the bed, all while maintaining comfortability. Read on to find out our top picks and the best protocols to follow when purchasing an anti-sag bed.
Our Pick for The Best Mattress That Won’t Sag
The Helix Midnight earned our top spot due to its overall versatility, responsiveness, and great edge support. It also has a sizeable coil count (more on that later). Despite being constructed to best suit side sleepers, this bed is an excellent choice for many types of sleepers.

How We Look For the Best Mattresses That Won’t Sag
At Sleep Advisor, our mattress reviews are based on findings from in-person tests that allow us to have a genuine understanding of how the mattress feels and performs. We take into account several factors through our diverse cast of testers: sleeping position, body type, and overall personal preference. You can trust our opinions knowing that we’ve touched and tested the mattress ourselves.
For this roundup, we focused on mattresses that we feel should hold up well over time and not sag. We took several factors into account when creating our list, mostly those that will affect sagging—such as coil count, foam density, and pressure relief. More on them below.
Advice from a Medical Expert
We reached out to Dr. Raj Dasgupta, who has over 20 years of experience in the medical field, to see his thoughts on what key qualities to look for in a mattress to prevent sagging.
“To steer clear of mattress sagging, focus on quality, support, and maintenance. Look for a mattress made of durable materials like sturdy foam or coils. Make sure it strikes the right balance between comfort and support and is neither too soft or too firm. Look for reinforced edges to prevent sagging, and consider a thicker mattress for added durability. Don’t forget maintenance and rotate the mattress regularly for longer-lasting support.
What We Want to See in a Mattress That Doesn’t Sag
When it comes to determining a mattress’s tendency to sag or its overall longevity, the construction can play a big role. Here’s some more specific details and why they matter when it comes to saggy mattresses:
Coil Count
Most people equate coil count with durability, and I agree. Coils help a mattress keep its shape, especially the outer edges–which is where we can see sagging over time with some beds. Plus, they help with long-term edge support. The more coils, the more support, and the less sagging. Less is not more.
Foam Density (ILD)
ILD stands for “indentation load deflection,” and measures the amount of force needed to compress a type of foam. The higher the force, the firmer the foam, and the more durable it’s likely to be. As my fellow tester Loren put it: “Mattresses with denser foam layers tend to be more durable—that’s why all-foam mattresses use the densest foam they can in the support layer.”
Generally, a “soft” ILD is from 10 to 20, “medium” is from 20 to 30, and “firm” is 30 and above.
When it comes to avoiding saggy beds, I’d also say aside from high ILD, just make sure the foam’s quality. Like if it has CertiPUR-US certifications, it’s the good stuff.
Pressure Relief
Pressure relief is the bed’s ability to alleviate pressure buildup in areas that dig into the mattress. We’ve said that firmer foams tend to be more unyielding and durable, but they also may struggle to properly relieve pressure. Softer foams work well for certain sleepers (like those of a lighter weight or who prefer their side), but can cause sagging over time.
Thus, it’s important to consider high-quality foams when we’re talking about pressure relief, so your bed won’t sag over time.
When it comes to the mattresses we chose for this roundup, we reached out to the company’s customer service directly to get accurate coil counts and foam densities–straight from the horse’s mouth.

Why the Helix Midnight Earned Editor’s Pick
When testing this bed, our reviewer, Emma, pointed out that the Helix Midnight is a killer value for the money. The mattress has reinforced steel coils around the perimeter, holding its edges so that they don’t collapse should you sit or sleep near this area. Sleepers shouldn’t feel like falling off the bed, which is a win for co-sleepers and single individuals who like to spread out across the entire mattress.
The Helix is a hybrid, so it combines foam with coils, offering decent bounce and pressure relief, but also motion isolation that partners with different sleeping habits should appreciate. These coils should also work to keep the bed from sagging.
What’s the Helix Midnight Made Of?
The Helix Midnight mattress is 11.5 inches tall and has four layers along with a top and bottom cover. The top one is a Soft Touch cover, or you can choose GlacioTex™, which is more suitable for hot sleepers.
Under the cover is a layer of Memory Plus Foam designed to contour the body and relieve pressure. Next, is a layer of high-grade poly foam, followed by an 8-inch coil unit. The base is made from Dura Dense Foam and is meant to provide additional support so that the upper layers don’t sag.
My Take: According to Helix’s customer service, a queen-size Midnight mattress has a total of 825 coils. This is comparable to others on this list, a decently considerable amount that should keep you supported without egregious sagging.
Customer Reviews of The Helix Midnight
The Helix Midnight rates 4.5 stars out of 5 on Helix’s website. The main negative is that reviewers tend to find it too soft for their liking and feel as though they’re sinking. But overall, users say they’re getting a great night’s sleep and some pain relief.

Why the Emma Hybrid Comfort Earned Best Mattress That Won’t Sag for Couples
Our review team thought this bed was perfect for couples, as it excels across multiple categories important for those sharing a bed. First, it features great motion isolation, which is helpful for partners with different sleeping habits. If your partner tosses and turns all night or usually gets up before you, you should be able to sleep through that movement.
The Hybrid Comfort mattress also feels sturdy around the edges, so you can spread out as much as you want while feeling nicely supported along the perimeter. We think this durable mattress should last a long time without sagging or losing its shape.
What’s the Emma Hybrid Comfort Made Of?
The Hybrid Comfort mattress has a soft-to-the-touch, breathable top cover. Underneath is a layer of Airgocell® foam, an open-pored material that helps absorb motion while also dissipating heat. Two more layers of foam follow: a memory foam layer to promote motion isolation and an HRX foam layer for support and firmness.
The innerspring unit consists of individually wrapped coils that target specific areas of the body with seven discrete support zones.
At the bottom, a sturdy base ensures stability for all 13 inches of the mattress. There’s even a bottom cover with anti-slip fabric that prevents the mattress from sliding around on your frame.
My Take: It’s worth noting that Emma’s customer service was unfortunately unable to provide a specific coil count for a queen Hybrid Comfort, but they gave us a range of 600-800 for all models. They did say that there were about 250 coils per square meter, which is a fairly good ratio that should produce a mattress with minimal sag.
Customer Reviews of The Emma Hybrid Comfort
This is a fairly new mattress, so Emma’s site doesn’t have many reviews yet, but early customers already rated it an impressive 5 out of 5 stars. So far customers appreciate the Emma Hybrid Comfort mattress for its excellent motion isolation, but some have reported that it may have a slight initial off-gassing odor upon unboxing.

Why the WinkBed EcoCloud Earned Best Eco-Friendly Mattress That Won’t Sag
The WinkBed EcoCloud mattress is hypoallergenic, non-toxic, and resistant to dust mites and mold. On top of that, the mattress is certified by various organizations, featuring OEKO-TEX100® and Rainforest Alliance certifications. The cover is made from organic cotton and New Zealand wool, but Talalay latex is the star of this bed as it’s antibacterial and hypoallergenic, on top of being breathable.
The combination of latex and coils should also make for a resilient sleep surface that won’t sag as it bears your weight.
What’s the WinkBed EcoCloud Made Of?
This 12.5-inch bed has organic cotton and New Zealand wool cover, followed by a 4-inch layer of Talalay latex. The latex in this bed has an open-cell structure, so it’s breathable and bouncy.
Next comes a layer of coils, providing zoned support to the heaviest areas. Finally, the bed has a foam base and reinforced edges with ExtraEdge™ Anit-Sag Support coils that help prevent it from sagging.
Our Take: WinkBed’s EcoCloud mattress features 848 coils in its queen model. This is pretty similar to other mattresses on this list and rather high, so you should expect it to hold weight well. The edges and middle likely won’t sag.
Customer Reviews of The WinkBed EcoCloud
At 4.8 out of 5 stars on WinkBed’s site, the EcoCloud has an overwhelmingly positive response. Customers appreciate the eco-friendly materials used in the WinkBed EcoCloud mattress but have noted that the price point may be higher than some competitors.

Why the Plank Earned Best Firm Mattress That Won’t Sag
The Plank mattress is a dual-sided bed, but both sides are on the firm side. More precisely, we rate one as firm and the other as extra-firm, so you can get an idea of how the mattress feels. This may not work for lightweight side sleepers, but we think it could be great for heavy sleepers and even average-weight stomach sleepers who like a firmer sleep surface. Additionally, it should provide excellent support for those with back pain and is unlikely to sag due to its firm construction.
What’s the Plank Firm Mattress Made Of?
The Firm side has a 1.5-inch quilted cover, whereas the Extra-Firm side has a .75-inch quilted top. If you look at the bed with the Firm side up, you’ll find a 2-inch layer of the company’s TitanFlex™ foam. The second layer is a 7-inch dense foam that acts as the base in this case. If you flip the bed, the 7-inch layer comes first, giving that side its firmer feel.
Our Take: The Plank Firm is an all foam mattress, so it doesn’t contain coils. But when it comes to the foam, it has a 30 ILD density rating, which is considered on the firmer end. This density rating suggests that the mattress will not sag.
Customer Reviews of The Plank Firm Mattress
On Plank’s website, the Plank Firm gets 4.8 out of 5 stars. Customers appreciate the Brooklyn Bedding Plank Firm mattress for its exceptional firmness, but some have found it to be too rigid for their comfort preferences.

Why the Nolah Natural Earned Best Mattress for Back Pain That Won’t Sag
The best beds for back pain will have a balance of support and pressure relief, and the Nolah Natural just does that. The combination of wool, latex, and coils not only promotes spinal alignment but also creates a responsive, comfortable surface. All of this contributes to lessening back pain in a variety of positions, but it also ensures stability and longevity. This means that the Nolah Natural should last you a long time without sagging, so you can enjoy eco-friendly, hypoallergenic, pain-free sleep for years to come.
What’s the Nolah Natural Made Of?
The Nolah Natural is 11 inches tall with a total of six layers when you include its covers. The top cover is made of organic cotton for a breathable and soft sleep surface.
The first layer beneath the cover is made up of natural Talalay latex, a breathable and bouncy material that relieves pressure buildup. A second layer of Talalay latex supports the layer above while transitioning into the bed’s coil unit.
Three zones of individually wrapped coils ensure the right balance of lift and give, keeping your spine aligned. Underneath the coil unit lies a stable wool foundation. Finally, the lower half of the mattress is swaddled in another organic cotton cover, this one featuring handles for ease of movement.
Our Take: A queen-size Nolah Natural has a coil count of 852. This is the same as our current editor’s pick, the Helix Midnight. This balances out the mattress’s use of pressure-alleviating foams, yielding a soft and supportive mattress that shouldn’t sag.
Customer Reviews of The Nolah Natural
On Nolah’s website, the Nolah Natural gets a 4.8 out of 5 stars. Customers appreciate the Nolah Natural mattress for its eco-friendly materials and pressure relief, but some have reported a minimal initial off-gassing odor upon setup.

Why the Saatva Classic Earned Best Innerspring Mattress That Won’t Sag
The Saatva Classic features not one but two coil units to provide excellent support and reduce the risk of sagging. The Saatva also benefits from the addition of memory for added comfort.
This mattress has zoned support in the upper coil layer, offering enhanced lumbar support for back sleepers. On top of that, it has quite some bounce coming from the two coil units, although the upper comfort layers dampen some of the movement to enhance motion isolation.
What’s the Saatva Classic Made Of?
Shoppers can choose from two options when it comes to height: 11.5 and 14.5 inches. Both models have the same layers. The difference is in the height of each layer.
The construction starts with a 3-inch Euro top that provides decent cushioning and contouring. Underneath is the Lumbar Zone® Active Spinal Wire combined with CertiPUR-US®-certified memory foam, followed by the first layer of pocketed coils. Next is the coil base unit with a high-density rail for better edge support.
My Take: The Saatva Classic has a whopping 1,300 coils in its queen size! It’s the highest on this list, no doubt thanks to its dual innerspring unit. We often tout it as one of the most durable mattresses we’ve encountered during testing, so it makes sense to say it shouldn’t sag.
Customer Reviews of The Saatva Classic
The Saatva Classic rates 4.8 stars out of 5 on Saatva’s website. One negative aspect customers found with the Saatva Classic mattress is that it may feel too firm for some users, while a notable advantage is its high-quality materials, providing durability and support.

Why the Titan Plus Earned Best Mattress That Won’t Sag for Heavy People
The Titan Plus mattress is constructed with heavyweight people in mind. This is a hybrid with memory foam and coils working together to deliver a combination of support and pressure relief where you need them the most. The mattress has TitanCaliber™ coils that ensure sturdy support and no sagging, even with sleepers over 230 pounds.
What’s the Titan Plus Made Of?
The construction starts with a cotton cover, although there’s also an optional GlacioTex™ cover for those who need additional cooling. The mattress is 11 inches tall and has a combination of memory foam and coils.
First, there’s a quilted cover with an inch of gel memory foam that adapts to your body and cools the surface. Next, is a layer of TitanFlex™ foam that provides targeted pressure relief and responsiveness for easy repositioning. This is followed by a layer of TitanCaliber™ coils and 2 inches of high-density foam acting as the bed’s base.
Our Take: According to Brooklyn Bedding, a queen Titan Plus has 720 coils. This is on the lower end when it comes to mattresses featured in this roundup, but it’s still plenty impressive when you consider that the proprietary “Titan Coils” are designed for industrial support.
Customer Reviews of The Titan Plus Mattress
Users on Titan by Brooklyn Bedding’s site have given the Titan Plus a 4.7 out of 5 stars. Customers find the Titan Plus mattress to offer exceptional durability and support, but some mention that it might be too firm for those who prefer a softer feel.

Why the Bear Original Earned Best Memory Foam Mattress That Won’t Sag
The Bear Original mattress was designed to provide a high-quality foam mattress experience at a fraction of the cost. It has a medium-foam feel that should cater to a variety of sleeping positions and body types. Where it really excels is in spinal alignment, thanks to its even distribution of weight and sturdy support. Its construction is also built to last, unlike most foam mattresses, which may be prone to sagging over time.
What’s the Bear Original Made Of?
The first thing that stands out is the cover, which is made from botanically sourced and breathable TENCEL™ fibers. You can also pay more to add a Celliant® cover, which Bear claims converts your body heat into infrared light to help with recovery. Underneath, is the 2-inch layer of memory foam infused with gel graphite for additional cooling. Next comes the 2-inch transition layer made of poly foam, followed by 6 inches of poly foam acting as the base.
Our Take: The Bear Original is an all-foam mattress with varying levels of firmness throughout its foam layers. The top comfort layer is 11 ILD, a softer feel. The middle transition layer is 24 ILD (medium) and the bottom base layer is 30 ILD (firm). This combination and order, plus the high quality of the foam, should work to keep the mattress from sagging.
Customer Reviews of The Bear Original
On Bear’s website, the Bear Original has more than 10,000 reviews and an average rating of 4.3 out of 5 stars. Customers appreciate the Bear Original mattress for its cooling features, yet some express concerns about an initial off-gassing odor.

Why the Signature Hybrid Earned Best Value Mattress That Won’t Sag
The Signature Hybrid mattress from Brooklyn Bedding is available in three firmness options so you can choose what’ll work best for you. Our tester Emma said that the Signature Hybrid is responsive with a comfortable yet supportive feel.
This bed should keep from sagging due to its robust coil unit, which also features reinforced edges to deter unwanted sinking. Most important of all, it comes in at a decent price—frequent sales bring the price of a queen down to just under $1,000.
What’s the Brooklyn Bedding Signature Hybrid Made Of?
This hybrid has two of the company’s proprietary foams combined with Ascension® coils. The first layer is made from TitanFlex™ foam infused with TitaniumGel™ for better temperature regulation. This layer has an open-cell structure that also helps keep the surface cool. Next comes a layer of VariFlex™ foam acting as a transition layer above the Ascension® coils. Additionally, the edges are reinforced with the same coils to prevent sagging.
Our Take: There are 840 coils in a queen Brooklyn Bedding Signature Hybrid. Not only is this impressive for a hybrid of this affordable price, it’s sure to keep the bed from sagging. The perimeter is reinforced, too, to keep the edges from giving out.
Customer Reviews of The Brooklyn Bedding Signature Hybrid
On Brooklyn Bedding’s website, the Brooklyn Signature has 4.7 out of 5 stars. The Brooklyn Bedding Signature Hybrid mattress receives praise from customers for its versatility with different firmness options, but some have mentioned that it may produce slight noise when bearing weight.

Why the Birch Natural Earned Best Mattress That Won’t Sag for Combination Sleepers
The Birch Natural is a super springy mattress made with (you guessed it) natural materials. It features organic cotton and wool alongside Talalay latex, all of which create not just a super-comfy sleep experience, but also a sturdy one. If the strong edges are anything to go by, this bed should perform up to par without any sagging. But above all, combination sleepers will be able to enjoy the easy repositioning they can get on top of this mattress, thanks to its bouncy feel.
What’s the Birch Natural Made Of?
The Birch Natural is about 11 inches tall. It has a total of six layers including a cover. Said cover is composed of organic, hypoallergenic cotton, leaving the surface soft and cool.
Next up is a layer of organic wool, which acts as a natural fire barrier. Another wool layer below continues the cushioning feeling while also adding insulation. The pressure relief layer is made up of natural Talalay latex for added responsiveness and breathability.
The coil unit is made up of pocketed coils that respond individually to your movements for maximum lift while isolating motion. Everything sits on a final wool base layer.
Our Take: The Birch Natural features 852 coils in its queen model, certain to bring the support. Alongside natural latex and organic wool layers, these should fight against sagging to ensure your mattress stands the test of time.
Customer Reviews of the Birch Natural
According to Birch’s website, the Birch Natural scores a 4.6 out of 5 stars. While some users consider the Birch Natural mattress to be on the pricier side, it gains customer appreciation for its organic materials and sustainable, eco-friendly construction.

What to Look for In Durable Mattresses That Don’t Sag
The first thing you should look for is durability and quality materials if you want a mattress that won’t sag. Since sagging usually occurs due to weak materials compressing under the sleeper’s weight, it’s important that the bed returns to its original shape once you get up.
Durability Components
It’s hard to quantify how durable a mattress is when so much goes into it: what it’s made of, who’s sleeping on it, etc. But we’ve discovered a metric that works well alongside our own testing within what we’ll call “durability components” of the mattress.
We mentioned it at the beginning of our list but here’s what you can think about. Basically, we’re looking at the support system of the mattress to see how they’ll measure up. There are two main ones to consider: coil count and foam density.
Coil Count
The coil count of a mattress refers to the amount of coils in a given (innerspring or hybrid) mattress. Usually, the number of coils increases with mattress size. Consumers have found that more coils often yields more support and increased longevity, and we agree.
As a general rule, try to find mattresses that have at least 500 coils—and we’re talking about queen sizes, here. It’ll differ for smaller or larger beds, but most mattresses we test are in the 600-800s, with some of the sturdier beds having upwards of 1,000 coils.
If you can find a bed with multiple coil layers, you can double or triple the longevity-increasing effects of the coils. Simply put: more coils, less chance of sagging.
Foam Density
But what about memory foam beds without coils? Well, we look at something called the ILD (Indentation Load Deflection). Simply put, it has to do with how far something (or someone) can sink into the foam before it’s “deflected”—AKA, go any further.
The ILD is represented as a number that also can correspond to a foam’s firmness. Foams toward the lower end, around 10 to 20, are considered soft. Those in the 20-30 range are considered medium, and those above 30 would be your firm foams. The quality of the foam also has an effect on the ILD, as higher-quality foams will keep their shape and firmness longer than lower-quality foams.
Other Considerations When Shopping for a Mattress That Won’t Sag
Trial & Warranty
Don’t trust a mattress to not sag? Well, good news, there’s plenty of ways to get reimbursed if your new bed happens to sag.
For one, a mattress trial allows you to try a bed before fully committing to it, usually offering free returns and refunds if you send it back within the allotted time frame.
A mattress warranty should not only give you an idea of a mattress’s lifetime, but it’s also useful to cash in when your mattress starts to sag sooner than expected. Many companies outline stipulations or timelines for when they can replace your mattress, repair it, or offer you some kind of refund. Usually, the longer you have a mattress, the less “lenient” the policies will get, as even the most highly-constructed mattress begins to show signs of age after, say, a decade of use.
Here are the trial and warranty lengths for the mattresses we recommend:
| Mattress | Trial | Warranty |
| Helix Midnight | 100 nights | 10-year warranty |
| Emma Hybrid Comfort | 365 nights | 10-year warranty |
| WinkBeds EcoCloud | 120 nights | Lifetime warranty |

| Bear Original | 120 nights | Lifetime warranty |
| Brooklyn Bedding Signature Hybrid | 120 nights | 10-year warranty |
| Birch Natural | 100 nights | 25-year warranty |
Firmness
Firmer beds may initially be less likely to sag, but if the materials aren’t of good quality, they could experience wear and tear sooner, which would eventually result in sagging. One thing to keep in mind is that some mattress firmnesses are more suitable for certain sleeping positions and body weights. For instance, if a person weighs over 230 pounds, they may prefer a firmer bed because a softer bed would likely sag under their weight.

Sleeping Position
Your sleeping position may affect how a mattress reacts to pressure and compression. For example, if a mattress is too soft for side sleeping, your shoulders and hips may cause it to sag in these areas. The same goes for other positions. If you’re a stomach or back sleeper, you want to avoid a softer bed that sags too much in the middle as this can lead to lower back issues.
Weight/Body Type of Sleepers
A mattress is likely to sag if you go over its weight capacity. For example, if it’s too soft to handle a person over 230 pounds, it’s going to sag under from bearing their weight. It’s difficult to tell how soon a mattress will sag, but it could sag sooner rather than later if you consistently put too much weight onto it.
For plus-size sleepers concerned about this, there are great brands out there that cater to heavier body types with mattresses that are made with denser, reinforced materials that are less likely to sag.
Cooling
Cooling is an important factor to consider and although it doesn’t have much to do with sagging, it can make a difference when it comes to comfortable sleeping. Many mattresses have cooling features such as gel, copper, and graphite infusions, an open-cell structure (if it’s a memory foam or latex), a cool-to-the-touch cover, and different technologies that help with temperature regulation.
One thing to point out is that hybrid and innerspring mattresses are typically cooler than memory foam because memory foam has a tendency to retain heat unless it has some type of cooling enhancement like gel or an open-cell structure.
Sleeping on a bed that doesn’t sag could also help you sleep cooler since you’re less likely to be enveloped in the layers, which could cause heat buildup.
Read more about cooling mattresses here.
Motion Isolation
Motion isolation is another common factor many sleepers look for, especially those who share their mattress with a partner, a child, or a pet. Motion isolation refers to the mattress’ ability to isolate movement coming from one side of the bed so that you don’t feel as much of it on the other side.
Memory foam beds are usually the best at isolating motion whereas latex and innerspring mattresses don’t perform as well for this because they’re more responsive and bouncy, which means movement travels more easily.
Flippability
If the mattress you’re considering is flippable, there’s a high chance that the edges will hold up better. For one, these mattresses are generally firmer than their non-flippable counterparts, as they have to bring support to not just one but two sides.
Moreover, with a flippable mattress, assuming you’re flipping it, you won’t be sleeping in the same spot on the same side for a prolonged time. This can be the culprit for why many mattresses sag.
Flippable mattresses also offer the option of having two different feels, a boon if you’re someone who cannot choose between a soft or firm surface—or if you just prefer to have the luxury of choice.
Pressure Relief
Pressure relief is important, but typically more so if you usually prefer sleeping on your side. Side sleepers often put a lot of pressure on the hips and shoulders, so it can help to have a mattress that can relieve some of that tension. Look for a bed that allows enough cradling and sinkage to prevent pressure from building up without taking away from the support. Even with sinkage and pressure relief, you want enough support to keep the spine aligned and to keep the mattress from sagging.
Be aware that softer beds can be more prone to sagging, so you’ll want to pick a pressure-relieving bed with a good support unit underneath, whether that’s a sturdy coil unit or a dense foam base.

Edge Support
Many sleepers find edge support to be crucial when looking for a mattress that doesn’t sag.
Edges are often the weakest part of a mattress, and they often sag more than the rest of the construction.
Have you ever experienced sinking or sliding off of a bed when trying to sit near the edge? This happens on mattresses with poor edge support.
One way brands enhance edge support is by providing additional reinforcement along the perimeter. In the case of hybrids and innersprings, you can find higher-gauge coils around the edges, whereas memory foam and latex beds have higher-density foams in this area.

Budget
Budget is something many of us have to think about when buying a new mattress, especially since many beds are quite pricey. The best thing you can do is to consider how much money you’re willing to spend on a mattress. Think about what you need from a mattress and set aside a budget. The good thing is that many brands offer discounts for major holidays and retail holidays like Cyber Monday and Black Friday.

How to Tell if a Mattress is Sagging
Is your mattress really sagging? There’s a possibility your bed is just suffering from normal wear and tear after years of use.
Normal Wear and Tear vs. Sagging
Most mattresses, regardless of their quality, will show some wear and tear over time. This is especially true if you sleep in the same position and same spot of your mattress every night. Over time, this will cause an indentation or divot to build up from repeated weight-bearing. It’s difficult to avoid this effect as, unfortunately, we can’t become weightless. (Not yet, at least).
Sagging is more egregious than normal wear and tear. Perhaps it occurs too fast (like in the example shown above) or feels too deep to be considered an effect of long-term use.
The cause usually stems from something else: for example, it could be due to a lack of structural integrity in the mattress itself that causes the bed to fail in supporting your weight.
Is it Time to Replace Your Mattress?
“A sagging mattress can hurt your sleep and health. It’s uncomfortable, messes with your spinal alignment, and creates pressure points, making you toss and turn all night. Plus, it can lead to allergies and increase the risk of injury. The bottom line is to ditch the sagging mattress for better sleep and health.”
Dr. Raj Dasgupta
Most mattresses have a lifespan of 10 to 15 years, with some wiggle room depending on the quality of their construction. If you’ve had your bed for that long (or longer), it’s possible your mattress has simply reached the end of its journey with you—it might be time to say goodbye and start anew.
However, if it’s only been a few years since you bought your bed, there are simple ways to address the wear and tear.
How to Fix a Sagging Mattress
Have you exhausted all your options but you’re not quite ready to fork over the cash for a new mattress? No worries, there are some ways you can help mitigate any existing sagging or prevent any further issues.
- Rotating your mattress – Sleeping on one side of the bed can cause sagging in that area, so a simple solution is to rotate your mattress 180 degrees every so often. This can give any sagging some time to breathe and decompress.
- Flipping your mattress – Sometimes flipping the bed over can provide you with a new, indent-free surface. Only do this if your bed has a flippable construction, though, as regular beds are designed with the comfort layers on top, and the support layers below.
- Change your foundation or frame – If your mattress sits on top of a weak foundation or frame, this could exacerbate sagging. This is especially true if your frame has wider slots that allow parts of the mattress to sink through. Some companies will also list what type of foundation is best for their mattress. Explore the best bed frames here.
- Change where/how you sleep – A last resort is to try and change how you yourself use your mattress. It might be time to switch to the other side of the bed, or try sleeping in a different position. We also want to note that jumping on the bed could cause quicker sagging, so it might be time to do away with any nightly pillow fights.
- Stay out of bed during the day – If you stay in bed all day, that’s an extra 12 hours this bed wasn’t planning on supporting you, and it may cause sagging to occur sooner rather than later. Not to mention there’s benefits to keeping your sleep environment intact outside of preventing wear and tear.
Best Mattress That Won’t Sag FAQs
What type of mattress is least likely to sag?
All mattresses can sag depending on their construction and how you use them. However, low-quality mattresses are going to be more prone to sagging because they lack the durable, supportive materials to withstand regular use. When it comes to those that won’t sag, we think that latex beds are your best bet since it’s a durable material that possesses a natural bounce-back. Another great option would be innersprings, as though coils can wear down over time, they’re much sturdier than foam. Combining latex and innerspring could doubly lessen the chance of sagging.
What causes a mattress to sag?
Most mattresses sag because their lifespan is coming to an end. Over time, your body and consistent sleeping habits will leave marks on your bed, but this may be only because it’s getting old rather than because it’s a low-quality mattress. However, jumping on a bed, sleeping on a mattress that’s not built for your body type, and poor-quality materials are also reasons why a mattress may sag.
How do I keep my mattress from sagging in the middle?
One of the best ways to prevent your mattress from sagging is to ensure the bed of your choice fits your body frame and preferred sleeping position. Rotating the mattress occasionally to even out the wear and tear across the entire surface of the bed can also help. You may also flip it (if it has a flippable design). We also recommend avoiding jumping on a mattress as this can break down the materials faster.
