Best Mattress That Won’t Sag

A saggy, uncomfortable mattress is everyone’s worst nightmare. While you may be able to catch some Z’s on a sagging mattress, they’re nowhere near as comfortable as beds without sags. That’s where we come in.

Now, all beds will sag eventually, especially after years of use. Still, some beds are more resistant than others to sagging and growing lumpy. You’ll be able to get a good night’s sleep on these beds for much longer than other ones.

Make more out of your new mattress by getting one that won’t sag as easily as the rest. We’ve made a list of the best mattresses that won’t sag to help you find a bed worth investing in.

At the top of today’s list is the Amerisleep AS3, a sturdy memory foam mattress greatly resistant to sags. It’s 12 inches thick and has a medium firmness suited for side and combination sleepers. Couples with slightly different firmness preferences will also love the balanced feel of the AS3.

Amerisleep mattresses include free shipping and returns, a 100-night sleep trial, and a 20-year warranty.

How Lying Down Feels

The AS3 is not only designed to maximize durability but to maintain a fine balance between comfort and support. Side sleepers gently sink into the surface for pressure relief, but not so hard they bow into their mattress. Meanwhile, back sleepers are buoyed by the base foam and targeted support features.

Inside the Mattress

The mattress cover of Refresh fabric does more than enable a lasting cool-to-the-touch feel. The minerals inside the fabric are thermoreactive, taking absorbed body heat and transforming it into infrared energy to promote greater recovery.

Under the AS3’s cover is 3 inches of Bio-Pur® foam. Compared to traditional memory foam, plant-based Bio-Pur® is significantly more durable and springy. Standard memory foam sags and sinks easily, whereas Bio-Pur® maintains its structure easily while still being comfortable.

Next is Affinity transition foam, which contains HIVE® zoned technology. HIVE® is divided into five ergonomic zones around your head, shoulders, back, hips, and legs. The technology offers different levels of cushioning and support to evenly distribute your body weight and align the spine.

The AS3’s base is made from Bio-Core® foam. This high-density foam is resistant to forming sags, lumps, and indentations so you can use the beds for years.

The Zoma Hybrid is another great hybrid option, especially if you tend to sleep hot or sleep on your side. Like other Zoma mattresses, the Zoma Hybrid is built to improve your sleep quality.

The Zoma Hybrid includes a 100-night trial and a 10-year warranty.

How Lying Down Feels

What stands out about the Zoma Hybrid is its coolness and buoyancy, lifting a sleeper and keeping the surface from growing overly warm. What may not attract as much attention is the medium feel, simply because it suits so many sleep styles. The hybrid’s surface is conforming without feeling too soft, excellent for sleepers who enjoy responsiveness in a bed.

Inside the Mattress

The Zoma Hybrid features lots of the same features as the classic Zoma Mattress, including gel memory foam and Reactiv™ foam wrapped in an AirCloth cover, which draws heat and moisture away from the body to keep you cool.

The first layer is gel-infused memory foam. These gel infusions prevent heat retention while the memory foam gently cushions achy body parts.

Next is a layer of Reactiv™ transition foam, an adaptive material designed to prevent sinkage. It responds rapidly under your body both to relieve pressure and align your body while you sleep.

Pocketed coils add extra bounce and support to the Zoma Hybrid. This stops you from sinking into bed and feeling “trapped” while sleeping. Plus, air can flow through the space between the coils so the bed doesn’t get overly hot. The foam base helps protect the coils so your bed doesn’t sag for years! Like we said, even the best beds sag eventually.

High-quality, long-lasting hybrid beds get expensive, but not the Vaya Hybrid. The Vaya Hybrid is a simple, yet durable mattress great for all types of sleepers. And despite being so affordable, the Vaya Hybrid is both CertiPUR-US® certified and made in the USA.

The Vaya Hybrid comes with a risk-free 100-night sleep trial and a 10-year warranty.

How Lying Down Feels

The Vaya Hybrid has a feel designed to provide near-universal responsive comfort. The buoyancy of its coils makes changing positions and moving out bed simple tasks, with no unwanted sinkage that will keep you trapped in bed.

The foam top gives the Vaya Hybrid a welcome edge of softness and conforming cushion, with one consumer reviewer noting the mattress helped ease back trouble from a previous bed.

Inside the Mattress

The Vaya Hybrid contains the same Vaya Comfort Foam as other Vaya beds.  It is a flexible material built to soothe pressure. It cushions your body without feeling overly soft or firm. Vaya Comfort Foam near-instantly snaps back into shape when you get out of bed or switch positions.

What makes the Vaya Hybrid different from the classic Vaya Mattress is the pocketed coil support system it contains. The steel coils support your spine and isolate motion transfer, so if you share a bed, you won’t disturb your partner when moving in bed.

The base of the Vaya Hybrid is a thin, but firm foam that absorbs shock from the springs. This prevents the springs from wearing out and going soft, ultimately ensuring the bed won’t sag.

The Nolah Natural 11 is a fantastic mattress for sleepers looking to stay away from synthetic ingredients with potentially toxic chemicals. This mattress stays away from petroleum products and synthetic fibers, opting only to use the purest natural ingredients like latex foam, cotton, and ethically harvested wool.

How Lying Down Feels

The first things you’ll notice about the Natural are its coolness and responsiveness. Both these attributes are thanks to the combination of latex and springs. Both latex foam and pocketed coils are breathable. That means the two of them work together to keep cool air flowing through your mattress.

Both of these materials are also incredibly responsive, so they combine to offer lots of pleasant bounce and fight body impressions.

Inside the Mattress

The Natural has six layers. Layer one is the Global Organic Textile Standard (GOTS) certified cotton cover. Layer two is a sheet of GOTS-certified wool for fire resistance and extra pressure relief. Both of these layers are highly breathable to keep the mattress surface cool to the touch.

Layers three and four are each made of perforated Talalay latex. The comfort layer consists of highly contouring latex to offer pressure relief, while the transition layer sports firmer latex to add buoyancy and support to the comfort layer.

Layer five is the HDMaxTM pocketed coil support system. This support layer offers 25 percent more support than your average coil system. It also features three separate zones to offer ideal support to each area of your body. Underneath the coil system, you’ll find the sixth layer, a foundation of cotton and wool that adds stability and durability to the support core.

When spending thousands of dollars on a bed, you won’t want it to sag quickly. That’s why we recommend the Amerisleep AS5 Hybrid. This soft—practically cloud-like—mattress manages to cushion the achiest parts of your body while still being supportive and resistant to sags.

The AS5 Hybrid includes a 100-night trial and a 20-year warranty.

How Lying Down Feels

The AS5 Hybrid is meant to mimic the imagined feel of a cloud with plenty of added bounce. The mattress is quick to embrace all the bodies curves, but the surface is responsive and avoids feeling like a sinkhole as you settle in bed.

Too much sinkage is a common drawback of lower-quality soft mattresses, but the AS5 Hybrid has a pleasing lift that doesn’t take away from its plush cushion.

Inside the Mattress

The AS5 Hybrid features the same cover and Bio-Pur® memory as the AS3 model we mentioned earlier. But that’s where the similarities end.

The AS5 Hybrid’s transition layer is made with a little something called Active Flex. This latex-like material adds the needs buoyancy and flexibility to the AS5 Hybrid, ensuring you never feel stuck or unsupported while sleeping. This layer also ensures the AS5 Hybrid is a good option for heavier individuals.

As a hybrid bed, the AS5 Hybrid contains a pocketed coil support layer. Springy coils prevent sagging but also enhance spinal support and motion isolation. Better yet, Amerisleep adds extra-firm coils on the side of the bed to prevent saggy edges. There’s a thin layer of foam beneath the coil unit to further stop sagging and wear.

Those who love the feel of innerspring mattresses should consider the Saatva Classic. This mattress makes a few tweaks to the original innerspring design to fix the most common complaints sleepers have with this mattress type. Namely, its inability to contour and its tendency to transfer motion.

How Lying Down Feels

The Classic retains the innerspring bounce that many sleepers have grown accustomed to while still making some needed upgrades. You’ll notice when you lie on this bed that it does bounce back under you, but it doesn’t transfer motion all over the sleeping surface. This is because the dual support core isolates motion.

You’ll also notice that the sleep surface does a much better job of following the curve of your body than a standard innerspring mattress. This is thanks, once again, to the dual support cores that add adaptability without sacrificing springiness.

Inside the Mattress

The Classic kicks the contouring into high gear right off the bat with a plush, quilted Euro topper for added pressure relief. The Lumbar ZoneTM quilting adds more support to the middle of your body to help keep your spine aligned.

Underneath the Euro top, you’ll find a layer of high-density memory foam to push support up another notch and offer even more pressure relief all at the same time.

Next, you’ll find the first of two support cores. This first support layer is made of pocketed coils. These individually wrapped coils are what make this bed more adaptable and motion isolating than a regular innerspring mattress. This is because each coil can move independently of one another, making the whole support core more flexible.

The second support layer is what gives the Classic mattress its classic feel. This layer consists of an open-coil network just like that featured in standard spring mattresses. That’s why you don’t have to worry about sacrificing the innerspring feel. The Classic is an innerspring mattress and a hybrid mattress all in one.

Both the support cores are surrounded on all sides by a high-density edge support railing system. These rails not only increase stability throughout the whole mattress. They also up the durability as well! That’s why you can expect to get at least 15 years out of the classic.

If you’re looking for an all-foam memory foam mattress that has the coolness of coils without the quicker breakdown and potential for noise, check out the GhostBed Luxe. This pure foam mattress features tons of amazing cooling features to make this mattress as pleasantly chilly as any hybrid.

How Lying Down Feels

This is a cooling mattress, so the first thing you’re going to notice is the cool-touch feel. Thanks to heat-wicking foams and fibers, that cool-touch feel will last all night long. So you don’t have to worry about waking up in a sweat.

However, this is also a memory foam bed. So it’s extremely contouring. You can expect it to take your shape in an instant to give you unbeatable pressure relief and adaptability. Yet it won’t take forever to bounce back into place, thanks to the Ghost Bounce layer.

Inside the Mattress

The GhostBed Luxe starts off with the freezing cold Ghost Ice fabric cover. As its name suggests, this fabric offers hot sleepers an icy blast to fight heat buildup and keep sweat at bay. The Ghost Ice fabric is aided by a layer of highly thermoconductive gel memory foam and a layer of cool burst fiber to ensure that cool-touch feel lasts for hours.

After the multilayered cover, you’ll find the even more cooling Ghost Ice layer and a thick comfort layer of gel memory foam. This cooling foam helps pull body heat even further away from you.

Beneath all these cooling layers sits the Ghost Bounce layer. This layer bounces like latex without all the allergy potential. This helps fight body impressions and ensure your bed bounces right back underneath you as soon as you move.

Finally, the Luxe boasts a layer of high-density foam to offer buoyancy and lift. This keeps you on top of the sleeping surface and ensures you won’t sink. It also means you can expect the Luxe to last a cool 25 years.

Heavier sleepers who can’t seem to find a mattress that doesn’t let them sink down should consider the Helix Plus. This mattress was designed specifically with big and tall sleepers in mind, and it has several technologies to make sure sinkage is not a problem.

How Lying Down Feels

You’ll notice the buoyancy of this mattress the second you lie down. It starts with ultra-dense foam even in the comfort layer to make sure your body cannot sink no matter what. Don’t let the firm feel fool you, though. The Plus still offers plenty of pressure relief for tired joints and sore muscles.

The Plus also has plenty of bounce to go around. Thanks to the highly responsive coils and Helix Dynamic Foam, it can spring back as soon as you move. So you don’t have to deal with slow response time or body impressions.

Inside the Mattress

The Plus offers two cover options: a breathable TENCELTM cover or a thermoconductive GlacioTex cover. Either one of these covers can help keep you cool all night long.

Next, you’ll find the ultra-dense four-pound memory foam comfort layer. This high-density foam is designed for maximum buoyancy and a medium-firm feel. So you don’t have to worry about losing cushioning to get extra support.

Underneath the high-density comfort layer, you’ll find the Helix Dynamic foam. This dense latex alternative doesn’t just fight sinkage. It also offers lots of responsiveness to make sure your bed bounces back as soon as you move.

A layer of firm memory foam comes next. This firm foam provides ergonomic support to keep your spine aligned and prevent back pain. It also provides an additional buffer between you and the pocketed coil system below.

Speaking of pocketed coils, you’ve got a support core of extra-tall pocketed coils directly beneath the foam layers to offer even more support than a standard pocket coil system. This coil system is the ultimate safeguard against sinkage.

Latex is one of the most durable mattress materials out there, but adding pocketed coils to it makes it extra supportive and cooling. Amerisleep does just that with the Organica Mattress, a latex hybrid bed with medium firmness.

The Organica includes a 100-night trial and a 20-year warranty.

How Lying Down Feels

While the Organica is a medium feel mattress like many of our other sag-free mattress recommendations, it still feels distinct due to its materials. The cotton, wool, and latex naturally promote a cool feel that synthetic materials can have trouble matching without infusions or added air channels.

The buoyancy of the latex, paired with the coils bounce, also make the Organica an easy mattress to move across. Sliding out of bed in the morning is a simple task with the Organica!

Inside the Mattress

The Organica is 13 inches thick and features a GOTS organic certified cotton cover. The first layer in the bed is 1 inch of New Zealand Joma Wool®, a cushiony material designed to stay cool while you sleep. With that, wool is also a natural flame barrier, meaning Amerisleep won’t have to use fiberglass or chemicals in the bed.

Under the wool is 3 inches of Talalay latex. It’s soft, like memory foam, yet still springy and durable. It snaps back into shape when you move or get out of bed to minimize sagging.

Amerisleep further ensures you don’t sink into bed with the pocketed coil layer. Each coil is wrapped in a thin fabric that minimizes wear, motion transfer, and squeaking. The layer closely supports your spine for the best possible comfort.

At the base of the Organica is 1 inch of Dunlop latex, a long-lasting material built to stop your bed from sagging.

Consider Your Mattress Type

Different mattress types have their own lifespans, along with their own prices and feels. The most common types of mattresses you’ll come across while shopping is memory foam, latex, innerspring, and hybrid mattresses.

Memory Foam

Memory foam mattresses usually last 8 to 10 years.

Sleeping on a memory foam mattress is great if you deal with chronic pain or simply want a cushiony bed with a hug-like feel. Since traditional memory foam mattresses can trap heat and sag easily, look for gel memory foam, copper memory foam, or plant-based memory foam. These beds are more breathable and durable compared to other memory foam options.

Latex

Latex mattresses have a lifespan of roughly 12 to 15 years.

Natural and organic latex mattresses are one of the most durable mattresses around due to their elasticity and springiness. Latex beds spring back into shape when you move or get out of bed, preventing sags. At the same time, latex mattresses are pressure-relieving, breathable, and supportive.

Innerspring

Innerspring mattresses last 5 to 7 years on average.

Innerspring mattresses are one of the most common beds around as they’re both affordable and sold through most mattress retailers. They’re known for their breathability and supportiveness, though cheaper innerspring beds tend to get unreliable and uncomfortable quickly due to their spring coil base.

Hybrid

Hybrid mattresses last about 5 to 7 years, just like innerspring mattresses.

A hybrid mattress features pocketed coils and a foam comfort layer. In a sense, hybrid mattresses combine the positive aspects of both innerspring and foam mattresses for optimal support and comfort. Hybrid mattresses isolate motion and support your spine well while also cushioning your pressure points and keeping cool.

How to Stop Your Mattress From Sagging

Although sagging is inevitable, properly caring for your mattress can restore sags and prevent your bed from sagging too quickly. This way, you make the most out of your investment and sleep comfortably for as long as possible.

Get The Right Foundation

The most crucial step to prevent a saggy mattress is by using the right mattress foundation. Your mattress’s foundation is what maintains its structure and ensures it lasts long to begin with. The wrong foundation can void your mattress’s warranty, meaning that when it does start sagging, you’re left fully responsible for repairing or replacing it.

Different types of mattresses need different foundations. Conversely, only certain mattresses will work with specific foundations. For example, shoppers tend to have more options when shopping for a platform bed than if they seek a mattress for an adjustable bed.

Memory foam and latex mattresses work with slatted foundations, solid foundations, adjustable bed bases, and platform beds.

Innerspring and hybrid mattresses work with box springs, slatted foundations, slatted foundations, and platform beds. Hybrid mattresses also pair with adjustable beds, but not innerspring mattresses.

Flip or Rotate Your Mattress

Another important aspect to stop sags is by flipping or rotating your mattress every six months or so. This helps distribute the pressure you place on your mattress throughout the years, preventing one large indent from developing in the bed.

Nowadays, most mattresses aren’t supposed to be flipped due to their top-down design—having a comfort layer on one end of the bed and a base layer on the other. Instead, rotating your mattress 180 degrees is the alternative to minimize sags and indentations.

Follow Your Mattress’s Warranty Guidelines

Above all else, make sure to stick to your mattress warranty’s care instructions. Your mattress’s manufacturer knows how to care for your bed best. Not adhering to their care guidelines can cause your bed to sag quicker and also void the manufacturer’s warranty. This means that when your mattress does eventually sag, the manufacturer won’t cover repairs or replacements.

Manufacturer care guidelines include what type of foundation to use, if and when to flip or rotate your mattress, and how to clean the bed. Most often, cleaning your mattress means spot cleaning and deodorizing your bed two or three times a year.

FAQs

What kind of mattress does not sag?

All kinds of mattresses sag eventually. It’s inevitable. Still, the type of mattress you have affects its durability to sags and ultimately its lifespan.

Latex mattresses have the longest lifespan, lasting about 12 to 15 years. Memory foam mattresses last roughly 8 to 10 years. Then, hybrid and innerspring mattresses usually last about 5 to 7 years.

How do I make my mattress not sag?

All mattresses sag whether we like it or not. After sleeping on the same bed for 10 years or so, it will develop lumps, soft spots, and yes, sags. That doesn’t mean you can’t prolong your bed’s life and prevent sags to the fullest extent.

We recommend:

• Using the correct foundation for your bed
• Rotating your mattresses 180 degrees bi-yearly
• Follow your mattress’s warranties care guidelines

Why does my mattress sag in the middle?

The main reason mattresses start forming a large indentation in the center is from carrying your body over the years. This is inevitable and usually appears regardless of if you’re petite, plus-sized, or average.

Another common cause of mattresses sagging in the center is a bad foundation. If your foundation itself is sagging or lacks a center beam, so will your mattress. With this in mind, most bed foundations last about 10 years.

How long should a mattress last before sagging?

Most mattresses last between 8 to 10 years before they sag and become unusable. Most mattresses come with warranties covering sags and last for about 10 years. So even if your mattress does sag sooner than this, you should be able to get it repaired or replaced for a prorated fee.

Some warranties last over 10 years—with some being lifetime warranties—so you’ll be able to repair or replace your mattress’s sags throughout the years to maintain it.

Can a sagging mattress cause lower back pain?

Yes, sleeping on a sagging mattress long-term can lead to lower back pain or worsen preexisting pain. Even a few nights on an old and saggy mattress may leave you feeling stiff, sore, and in pain. Avoid this pain by replacing your mattress every 8 to 10 years and using a sturdy foundation for your bed.

Conclusion

While all mattresses, even the best mattresses, sag eventually, we hope our list gives you some ideas on what beds are most resistant against sags. Look for beds made with durable materials and good warranties as well, so if your bed ever does sag, you’re covered! And remember, properly caring for your mattress is crucial to helping it last as long as possible and ensuring you get a restful night’s sleep.
