Sagging mattresses are the worst. If you’ve owned a mattress for longer than a few years, you’ve likely experienced this yourself — the dips, the trenches, the once springy foam layers laying dormant in your bed. But while some sagging may be inevitable, there are ways to prevent it from going overboard. How, you ask? Well, allow me to explain.

In this guide, I’m going to introduce you to some of the best mattresses that won’t sag. As you’ll notice throughout this review, all of these beds feature strong support layers that maximize the durability and stability of their structures. So, not only are these cuddly beauties sturdy, and not only are they comfortable, but they’re specifically built to stand the test of time.

How I Picked

Now that we’ve gone over my choices, let’s get into the methodology I used to select them! You can think of this section as a round-up of all the major factors you’ll want to consider when searching for a mattress that won’t sag.

Best Innerspring Mattress That Won’t Sag

The Saatva mattress in the Sleepopolis studio.


In the market for a supportive innerspring mattress that won’t sag while you sleep? Then you may want to consider the Saatva mattress. Made with a sturdy coil-on-coil construction, this bed is firm, bouncy, and built for the long haul. 

Durability points aside, my favorite thing about the Saatva is how well it supports a neutral spine alignment. What this means for me is that it lifts the hips in line with the shoulders, creating an even line across the body. This alignment not only makes it super easy to move around and change positions, but it also helps to alleviate tension at the joints and lower back. Another fun bonus? The Saatva comes in three different firmnesses, so you can really hone in on the comfort level that’s right for you. All in all, this is a well-made bed designed to withstand a lot of wear and tear.

Best Hybrid Mattress That Won’t Sag

Winkbed2 1


Hybrid mattresses can be fantastic options for folks in need of a durable structure as they’re built with both foam and coils. This means they get the best of both worlds — cozy pressure relief up top and firm support below. Thankfully, there are a lot of hybrid models available on the market today, with one of my faves being the WinkBed mattress. 

What sets this model apart is its super sturdy construction. While the pillow top itself is pleasantly plush, the rest of the bed is anything but. After sinking through the top layers of soft foam, you’ll land on a springy section of microcoils, which is quickly followed up by a tall system of pocketed coils. This results in a ton of bouncy support that brings some much needed heft and lift to the structure. Overtime, these coils will also help to support the top layers of foam as they begin to naturally sag and change shape. Because of this, we’ve also featured it in our best hybrid mattress 2021 round up!

Best Latex Mattress That Won’t Sag

The Zenhaven mattress.


If you like the idea of a foam mattress, but are worried about its long term durability, you may want to check out some latex options. Latex is an all-natural foam material with a quick response to pressure, so snaps back into place with ease. Plus, it holds its shape well over time, no matter the wear and tear. For a latex introduction, let’s talk about the Zenhaven mattress.

Built with three layers of Talalay latex foam, the Zenhaven mattress is sturdy, bouncy, and supportive. It’s also flippable, which allows you to oscillate between either a “Medium Firm” or “Firm” feel. I should also add that latex is naturally cooling, so could be an excellent choice for hot sleepers. All in all, this mattress is a cozy dream made of high-quality organic materials that have been designed to last much longer than other foams you might see on the market.

Best Cooling Mattress That Won’t Sag

The DreamCloud mattress.


Hot sleepers on the prowl for a cooling mattress that’ll keep its shape for years (and years) to come should take a peek at the DreamCloud. This hybrid is seriously comfortable and designed to keep temperatures low as you doze. 

Built with a quilted cover over layers of gel-infused memory foam and pocketed coils, this bed strikes a nice balance between pressure relief and support. The gel infusion in its top layer helps to absorb and dissipate body heat while the spaces between the coils encourage airflow throughout the structure. There’s also some nice edge support incorporated around the coils, which both maximizes the usable surface area of the bed and increases the longevity of the mattress as a whole. In short, this is a high-quality mattress built to keep its shape overtime.

Best Memory Foam Mattress That Won’t Sag

Layla Hybrid Mattress

Layla Hybrid

If you’re looking to snag a memory foam mattress that won’t sag, I’d recommend taking a look at the Layla Hybrid mattress. When compared to other memory foam options on the market, this one does the best job of supporting the top layers of plush foam so as to avoid any pesky sagging. 

How does the bed pull this off? By utilizing a sturdy hybrid design. As we mentioned earlier, a hybrid mattress uses foam and coils to strike a balance between cozy sinkage and firm support. What’s especially cool about the Layla Hybrid in particular is that it’s flippable. This means you can literally flip the mattress around to achieve either a “Soft” or “Firm” feel, depending on your needs. Either way, you’ll be greeted by cooling copper-infused memory foam and firm pocketed coils, which work together to establish a comfortable (and durable!) sleeping experience.

The Layla Hybrid uses foam and coil layers for two firmness options so you can choose the right support level for your sleep style. 


First and foremost, you’ll want to think about the materials at play. This may seem an obvious starting point, but you’d be surprised how much easier your search will be once you understand how certain common mattress materials respond to pressure over time.

For instance, poly foam is not going to be nearly as durable as memory foam, which, in turn, isn’t likely to last as long as high-density poly foam or latex. And though both pocketed coils and steel springs bring a lot of heft to a structure, steel coils typically last longer than individually wrapped (or pocketed) coils.


While better understanding the materials themselves is important, it’s also crucial to consider how the materials are combined within a mattress. When it comes to preventing sagging, the key here is to focus on the support layers.

When I think about support, I’m thinking about the foundational layers of the mattress. Typically made of either pocketed coils or high-density poly foam, these sections are meant to stabilize the structure and provide support to both the sleeper and the softer comfort layers above it. In the case of sagging, a strong foundation will ensure that any changes to said comfort layers won’t dramatically alter the feel of the mattress.

In my opinion, pocketed coils and steel springs make the most supportive foundations. So, if durability is a major consideration for you, I’d recommend sticking with either a traditional innerspring mattress or a hybrid mattress made of both foam and coils.


If you’re really concerned about sagging, you may want to go with a flippable mattress. There are more and more flippable models available on the market all the time, and they can be great options for folks who want to extend the life of their mattress.

And the reason why is quite simple — if you notice any sagging or dips in your mattress, you can easily flip the bed over to get a fresh feel. Though it may feel a bit laborious, oscillating between the two sides can help prevent any one part of your bed from getting too worn down.

It’s important to note that not all mattresses are flippable. But, if you want to achieve a similar vibe, you can always rotate your mattress every few months to even out the sagging across the surface.


You’ll also want to consider the warranty on your mattress. While most brands provide some sort of limited coverage, the extent to which your mattress can get replaced varies widely across the market. So, make sure to read the fine print to see what exactly is covered.

If your mattress happens to come with a robust warranty, this will extend its longevity well into the future. Though a great warranty may or may not be a selling point for you, it can help alleviate worries about “sagging” or general wear and tear.
