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 2022 roundup!

As the luxury version of the Helix Midnight, the Helix Midnight Luxe adds zoned support and a cushy pillow-top to the top layer of memory foam. When lying down on it, side sleepers should experience a good deal of pressure relief while still getting support from a layer of individually wrapped coils. The coils also help prevent the bed from sagging. It’s worth noting that the Luxe is slightly firmer than the standard version of the mattress.

The Brooklyn Bedding Titan is designed specifically for heavy people over 250 lb, with extra-supportive touches such as responsive Titanflex foam in the comfort layer and an extra-tall layer of TitanCaliber-encased coils at the base. All of these materials work together to establish a 7.5/10 firmness that should appeal to heavier sleepers in all three sleeping positions. An added bonus of all this reinforcement is that the Titan is extra-durable, which means it should easily prevent sagging.

At a 7 out of 10 on the firmness scale, the DreamCloud offers plenty of support to back sleepers. It also has a layer of pocketed coils, which should assist with the prevention of sagging. But another notable feature of this mattress is its cooling capabilities. The coils leave plenty of room for airflow, and the comfort layer of memory foam has an infusion of cooling gel to further help with temperature regulation. Plus, the cover is made with a special cashmere blend and quilted with a bit of foam for added plushness, making this mattress luxurious and cozy on top of being cool.

If you like the idea of a foam mattress but are worried about durability, you may want to check out Nectar’s gel memory foam mattress — it’s a durable, high-quality option that comes at a great price for budget-conscious shoppers.

This pressure-relieving yet supportive bed has a thick gel memory foam layer, which carries all the comfort qualities of traditional memory foam, but provides better cooling. Additionally, the 4″ layer of dynamically adjusting foam adds bounce to the mattress, preventing sleepers from sinking too far into the bed. The materials of the Nectar — both comfortable and supportive — make it a great memory foam option for a mattress that doesn’t sag.

Good edge support, or how well a mattress holds up on the sides, is also extremely important for preventing sagging. Luckily, the Nectar has fantastic edge support, especially for an all-foam mattress, and this should keep side sleepers, back sleepers, and even couples satisfied.

Sound interesting? Then head on over to my full Nectar mattress review.

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. 

Read all about it at my full Saatva mattress review.

What to Consider When Buying a Mattress That Won’t Sag

Materials

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.

Support

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.

Flippability

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.

Warranty

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.

Summary: The Best Mattresses That Won’t Sag

Our Methodology

We’ve reviewed more than 220 products in our mattress lab, running each one through tests such as pressure-mapping and measuring motion transfer with a seismometer. From there, we give every bed an overall score based on materials, comfort, support, cooling, and edge support. We also factor in brand performance with categories such as value and warranty.

For a durable mattress, the quality of materials and the level of support serve as two of the most important factors. All of the mattresses that we selected for this roundup scored at least a 4 out of 5 for materials, and 4 out of 5 for support.
