Best Cooling Mattress

For many sleepers, sleeping hot is a nightly frustration that is a perpetual detriment to restful and comfortable sleep. Your weight, home, climate, age, and personal preference can all impact how hot you sleep, and if these factors do cause you sleep hot, you need a cooling mattress that will help draw the heat away from your body. The combination of your mattress, mattress protector, sheets, and bed foundation are all involved in how cool or warm your sleep experience is, but your mattress is definitely the most expensive piece of the puzzle, so making the right decision is paramount.

For this guide we’re going to focus on the best mattress for hot sleepers. These are sleepers who I would describe as above average in terms of their cooling needs. The reason why you sleep hot isn’t as important, all that really matters is you sleep warm and you need the right combination of mattress and other bedding accessories to help better manage the temperature regulation of your bed.

Best Cooling Hybrid Mattress

Back sleeping on the Helix Twilight

Helix

Looking for a cooling mattress that isn’t all-foam? Then check out the Helix line of beds. These hybrid mattresses use a combination of foam and coil layers for a balance of comfort, support, bounce, and mobility. The standard line includes six hybrid mattresses ranging in firmness from soft (e.g. the Sunset model) to firm (e.g. the Dawn). 

No matter the model you choose, all Helix mattresses have several features that are meant to promote cool sleep. The coil layer creates space for airflow through the mattress, and the various models incorporate breathable foams and covers to help defend against trapped heat. Along with its Standard line, Helix also makes all of its models in Luxe versions, which feature additional foam and zoned support for extra comfort. There’s also a Helix Plus model, an extra-durable bed designed for heavier folks.

Best Mattress for Hot Sleepers

The Brooklyn Aurora in the Sleepopolis bedroom

Brooklyn Bedding Aurora

Good news, hot sleepers: The hybrid Aurora mattress from Brooklyn Bedding was designed explicitly for sleeping cool. Its cover is made with a Phase Change Material that’s cool to the touch, and the Titanflex foam comfort layer is designed to provide pressure relief without trapping heat. Meanwhile, the coil layer allows for plenty of airflow through the mattress. 

The Aurora’s hybrid construction also accounts for its overall feel. The Tifanflex foam provides some nice comfort and pressure relief, while the coils lend the mattress great bounce and mobility. This balance of comfort and support creates a medium firm feel that could work well for back and side sleepers, as these folks need both lift at the hips and give at the shoulders for proper spine alignment. The foam also happens to do a great job of minimizing motion transfer across the bed, so the Aurora could also be a nice cooling option for couples.

Best Cooling Memory Foam Mattress

Layla mattress with the soft side up

Layla Mattress

Memory foam sometimes has a reputation for sleeping hot, but the Layla defies these negative expectations. This all-foam mattress sleeps cool thanks to a copper infusion in its memory foam comfort layer, which helps draw heat away from the sleeper. The bed also features a gel-infused cover that assists with temperature regulation and cooling. 

The Layla is a flippable mattress, with one side being firmer than the other. No matter which side you choose, you’ll find the same cooling properties as well as a layer of memory foam for some great pressure relief. If you’re a back sleeper, you’ll probably feel best on the firmer side, which should keep the hips elevated and aligned with the spine. Side sleepers will probably prefer the plusher feel of the soft side, which should help relieve pressure around the shoulder and hip. Bottom line? If you love the body contouring feel of memory foam but need to sleep cool, check out the Layla.

Best Cooling Mattress for Back Pain

The WinkBed Mattress

WinkBed

The WinkBed could help you combat back pain by promoting spinal alignment in multiple sleep positions. And it’ll do that all while sleeping cool. This is a bed-in-a-box, hybrid mattress with a pillow top and a coil-on-coil support structure. The coils allow for airflow through the mattress, while a gel infusion in the Euro top helps dissipate body heat to keep you sleeping cool. The mattress also uses a cover made with Tencel, a natural material that’s pretty breathable. 

As for the issue of back pain? The WinkBed’s sturdy construction creates a medium firm feel with a balance of pressure relief and support. This should serve back, side, or combo sleepers who are looking for relief from back pain. While back sleeping, the supportive mattress should help keep the hips elevated and the spine aligned, which can combat achiness. The mattress should also offer adequate pressure relief for side sleepers, who don’t want to feel jammed up at the shoulder. So if you want to avoid back pain and sleep cool, consider the WinkBed.

Best Cooling Mattress for Back Sleepers

The Bear Mattress

Bear

Back sleepers need to be mindful of maintaining healthy spinal alignment so they don’t get achy, and the Bear’s construction should help you do just that. This all-foam, bed-in-a-box mattress has a firm feel to keep the hips in line with the shoulders while back sleeping. At the same time, the memory foam comfort layer provides a touch of pressure relief to help alleviate tension along the spine. 

Does the Bear also sleep cool? You bet! The memory foam layer is infused with graphite to help draw heat away from the sleeper’s body. Additionally, the cover is made with Celliant, a breathable material that allows for airflow through the mattress. There’s also some evidence that Celliant could help with athletic recovery, so this could be a great mattress for athletes. If you’re into the cooling properties of the Bear but want a softer mattress, consider the Bear Pro. Or look at the Bear Hybrid if you want a cooling mattress with more bounce.

Best Soft Cooling Mattress

The Nolah mattress in the Sleepopolis bedroom for review

Nolah

The plush Nolah mattress pulls off a rare feat in the mattress world: It allows sleepers to sink deeply into the mattress without feeling trapped in a nest of heat. The all-foam, bed-in-a-box mattress uses a proprietary material called AirFoam, which is a cooler alternative to memory foam. Just like memory foam, it provides great pressure relief and body-contouring. But it’s more breathable than conventional memory foam, which helps the mattress stay cool even when you’re “in” it.

Side sleepers are the most likely to enjoy the feel of the Nolah as it’s designed to let you sink in for some great pressure relief around the shoulder and hip. At the same time, the firmer poly foam layers beneath the memory foam are supportive enough to promote healthy side sleeping spinal alignment. The soft foams on top of the bed offer yet another perk: They help cut down on motion transfer. That means this could be a great cooling mattress for couples who prefer a softer bed.

Best Cooling Mattress for Side Sleepers

The Casper Wave Hybrid in the Sleepopolis bedroom

Casper Wave

If you’re a side sleeper worried about sleeping hot, then the right mattress for you will need to meet some specific criteria. The Casper Wave should have those covered. Its zoned support system should address the unique needs of side sleepers. This system gives more pressure relief around the shoulders while providing more firmness around the hips. This helps maintain side sleeping spinal alignment without creating the “jammed up” feeling that can happen to side sleepers on a too-firm mattress. Overall, the mattress has a plush feel that lets you sink in for pressure relief without throwing your spine out of whack. 

Okay, so that takes care of concerns about side sleeping. What about sleeping hot? The Casper Wave uses an open-celled foam in the comfort layer, which allows for plenty of airflow through the mattress. If all of this sounds great but you want more bounce than an all-foam bed can provide, consider the hybrid version of the Casper Wave.

Could the Casper Wave help you side sleep soundly? Find out in our detailed review.

Best Organic Cooling Mattress

The Birch mattress uses great natural materials

Birch

Just as concerned about finding a bed with natural materials as you are about buying a mattress that sleeps cool? Then take a look at the Birch. This mattress features a wool and organic cotton cover as well as a wool comfort layer and an all-natural Talalay latex layer. Together, these materials create a natural mattress that does a great job of sleeping cool. The latex helps dissipate body heat, the cotton-and-wool cover is breathable, and the pocketed coil layer allows for additional airflow.

In addition to creating a cooling sleep environment, the materials in the Birch also contribute to its overall feel. The pocketed coils provide strong support, while the latex features a quick response to pressure. You’ll sink in for a touch of pressure relief, but it should still be easy to move around and switch positions. The standard Birch offers firm support and keeps sleepers elevated on top of the mattress, so it’s probably best for back or stomach sleepers. (These positions require a supportive mattress to ensure the hips don’t bow in and throw the spine out of alignment.) If you’re a side sleeper, consider adding the Birch’s optional topper to create a softer sleep surface.

Best Cooling Mattress for Combo Sleepers

The Purple Mattress

Purple

Combo sleepers need a mattress that allows them to enjoy comfort and support in multiple positions, and that’s exactly what you’ll find on the Purple. It’s a medium firm mattress that provides support and pressure relief in a variety of sleep positions. It also allows for great mobility, so you should be able to switch positions easily without feeling stuck in the mattress. And it does all this while sleeping cool.

How does the Purple boast all these attributes? A lot of it comes down to the bed’s proprietary hyper-elastic polymer grid. This polymer is a super bouncy material that’s also temperature neutral, and the grid construction allows space for air to flow through the mattress. That grid also accounts for the bed’s balance of support and comfort: It collapses where you need the most pressure relief and remains upright in places where you need support. It also helps minimize motion transfer, so this bed could be a nice option for couples. The polymer grid pairs nicely with the breathable cover, which is made from a stretchy blend of polyester, viscose, and lycra.

What materials make the best cooling mattress?

The materials used in the mattress are an important factor in determining whether it sleeps cool, warm, or hot. In any case, there really is just one fundamental factor that determines cooling. How well (or poorly) a material is able to breathe, allowing air in and out of the material.

For example, a traditional spring coil can easily breathe, given that the coils are very thin and at most will be wrapped in a thin layer of foam or fabric, however, there is still lots of air between each coil. A material like memory foam may not breathe as well as a coil, as there is simply more material preventing air from circulating in and out of the mattress.

Similar to breathability, a material’s heat conductivity and heat retention is important. A steel coil isn’t great at absorbing your body heat and it’s even worse at holding onto that heat. However, a traditional memory foam soaks up body heat and retains it, usually causing that memory foam to feel a bit softer and warmer.

Over the course of the last couple of years I’ve tested all major online mattress companies in the US and a handful of the big brands as well. In that testing I’ve come to believe that the cooling of materials is generally ordered as follows (from most cool to least cool):

  1. Coils
  2. Latex
  3. Gel
  4. Advanced poly foams
  5. Advanced memory foams
  6. Basic poly foams
  7. Basic memory foams

It’s important to remember that the materials used alone are not the only factor that determines the cooling of a mattress. The combination of materials, layer design, and cover also play an important part.

Coils & Springs

These are what you would describe as the most traditional of mattress types. They use one or more layers of coils / springs. As such, they are primarily air with thin coiled metal springs that provide comfort and bounce for the mattress. Bear in mind, most coil mattresses still contain some foams (usually poly foam or memory foam). These foams are mostly quilted within the covers of the mattress. Many times they are not explicitly disclosed.

Latex Foam

Latex foam doesn’t change its feel based on how hot or cold the room is because it is not a good conductor of heat. It always will feel the same. Additionally, most latex foam layers are aerated, which allows for greater airflow. This combination of factors makes latex a great option for cooling in a mattress.

Response time on latex is very quick, note the fast bounce back
Response time on latex is very quick, note the fast bounce back

However, this is only true of 100% natural latex. Blended or synthetic latex is aerated in the same way, but they also share qualities of a poly foam, in some respects. This isn’t to say that all synthetic or blended latexes are bad or not cool, they certainly can be. However, you’ll want to be sure you know the types of latex being used in the mattress to make a proper judgement call.

Gel & Infused Materials

In shopping for a mattress you’ll see lots of gels, gel infused foams, copper infused, graphite, and other materials. Using these materials isn’t bad, in many cases they can and will help to regulate temperature within the mattress. However, it is heavily dependent on how those materials are being used.

A true gel works like water. Water helps cool because it can absorb an enormous amount of heat before the temperature of the water has been discernibly changed. Gel works the same way. It absorbs heat and holds it. In this way, a gel has a maximum level of heat it can absorb before it too will begin to heat up.

Poly foam infused with copper and gel

That said, it’s important to note that just because a mattress has gel in it doesn’t mean it’s going to make that big of a difference. Swirled gel and gel beads have very little impact, in my opinion. That doesn’t mean that the foams aren’t cool, they still may offer great cooling due to other factors in the foam and mattress at large. However, gels and other infused materials included like this have a small impact.

Some foams are more completely infused with these materials, and the gel, graphite, copper, or other conductive materials permeate the foam more fully. In these cases, there is more of a notable impact on cooling performance.

Polyurethane Foam & Memory Foam

All thumbs are fingers, but not all fingers are thumbs. This type of relationship is also true about polyurethane foam and memory foam. All memory foams are poly foams, but not all poly foams are memory foam. 

Memory foam, also known as visco elastic memory foam and visco elastic poly foam, is a type of polyurethane foam with visco elastic properties. Visco elastic simply means that memory foams have both viscous and elastic characteristics when under pressure. Essentially, they are slower to respond when pressure is applied / released. This affect creates great hug and contour, but for some sleepers it can lead to a trapped feeling that can diminish cooling.

Gel memory foam - response and contour example
Gel memory foam – response and contour example

Poly foams are made from the same basic stuff as memory foam, however, they do not have a visco elastic qualities. This usually means they respond more quickly when pressure is applied / released. It also means the type of hug they create is generally less dramatic.

It’s important to note that the material “memory foam” is not a single type of material. Memory foam is simply a classification of a poly foam that is visco elastic. As such, there are scores of different types of memory foam with different qualities and attributes. The same can be said about standard non-visco elastic poly foams.

What’s the best mattress design for hot sleepers?

While it is important to understand how the material a mattress is made from can impact cooling and heat performance it’s more critical to understand how these materials work together within the larger design of the mattress itself. For example, you will almost never see a mattress that is 100% traditional visco elastic memory foam from top to bottom. Instead, you’ll have a layer or two of memory foam and a layer or two of poly foam. These materials work together to create airflow and a comfortable cooling surface on the mattress.

Below are some of the designs for the most popular mattresses and how these designs facilitate cooling:

Leesa – a top layer of Avena foam sits on top of a layer of memory foam and then finally on top of a layer of base poly foam. Avena foam is similar to latex in its cooling properties, which is why it makes more sense to have it closer to the sleeper. Placing the memory foam below Avena helps to prevent any of the heat retention issues of that memory foam from impacting the sleeper.

Saatva – a euro-style pillow top sits on top of two layers of coils. The two layers of coils means the Saatva is mostly air. There’s not much material to get in the way of breathability or allow for heat retention. The euro-style pillow top does contain some memory foam, but the layers are thin enough that they cannot absorb a significant amount of heat.

Purple – a top layer of a gel elastic polymer on top of two layers of poly foam. The elastic polymer top layer does not absorb a significant amount of heat. Additionally, the grid design of this polymer layer means more airflow. Having this layer on top ensures sleepers have the most cool surface closest to contacting them.

Helix – layers of performance poly foam, microcoils, and transition / support poly foam. In most Helix configurations the layer of Helix dynamic foam is on top. Having this on top helps prevent any type of heat retention. The microcoil layer is mostly air, which further improves breathability. The poly foam layers are generally used more in the core and base of the mattress, helping to mitigate any type of heat retention they might create.

WinkBed – Last, but certainly not least, the Winkbed mattress. I find that this bed is a great choice for sleepers that tend to overheat because it has a nice tencel cover (very breathable) and a nice coil on coil structure that means a lot of airspace in the mattress. Breathability is a huge asset when looking for a mattress that sleeps cool. The more airflow through a mattress the better and less foam in the construction is generally a plus.

Cool Mattress Designing with Airflow in Mind

Many companies understand how important a cool mattress is and take their material design to the next level by further improving the airflow capabilities. These companies use special machines to mold, compress, or cut the foam into a design that allows greater movement of air.

The most basic level of this technique is to punch holes within the top of the foam.

Example of an aerated latex foam layer
Example of an aerated latex foam layer

More advanced techniques create deeper and more pronounced channels within the foam, dramatically improving airflow.

How does a cover effect mattress cooling?

The mattress cover is perhaps one of the most overlooked aspects of the mattress’ functionality. However, the cover can play a major role in how cool or hot a mattress sleeps. In general, the less material within the cover the better the cooling will be. This is simply due to having better airflow in and out of the cover.

Bear in mind, the cover can only be as cool as the foam / coil layers below (except in rare cases, see phase change material below).

Non-Quilted Covers

Non-quilted / thin covers are the most popular and widely used cover on many online mattresses. In part because they are less expensive than quilted covers, but also because they offer better breathability. A thin cover simply has less material. Less material means less to get in the way of air circulating in the mattress, which ultimately means better cooling on the sleeping surface.

Thin mattress cover example - Helix mattress pictured
Thin mattress cover example – Helix mattress pictured

Quilted Covers

Quilted covers offer a more traditional look and feel, but can also mean a little more heat as there is simply more material now surrounding your body. The materials that are quilted within the cover also can play a factor here. Usually a thin low density memory foam or poly foam will be quilted within the cover.

Most traditional mattresses use a quilted cover.

Quilted cover example - Nest Bedding Alexander Hybrid

Phase Change Material

In describing these materials they almost sounds too good to be true. A phase change material works by absorbing your body heat and then releasing it at a certain temperature. Phase change materials, also known as PCMs, are tuned to a specific temperature. They will continue to absorb heat until the heat source (your body) has reached that temperature.

If your body’s temperature drops below that tuned temperature point then the PCM will release that heat back out, seeking the equilibrium temperature that it has been designed to achieve. In this way, phase change materials are great for both sleepers who sleep too hot and those that sleep too cold.

Phase change material example - Outlast

Other Cooling Fabrics

Other special fabrics and fibers can help to enhance breathability and cooling as well.

  • Celliant – this is a thermo-reactive fiber that turns your body heat into infrared light. Infrared light has been shown in studies to increase oxygenation of the body, which results in better internal temperature regulation.
  • Lycra – this a special fiber you more commonly see in sports clothing. It has an elastic type of a feel, moves freely, and wicks moisture away.
  • Performance Polyester – these are also more commonly seen in sports clothing, like Nike’s Dri-FIT collection. They work in the same way as Lycra, by helping to allow free movement and wick moisture.

Mattress Softness & Sinkage Impact on Cooling

As discussed above the more material that is wrapping around your body the more likely you are feel warmer. This is simply due to the fact that you have more foam and fabric coming into contact with your body.

As a general rule, mattresses that are softer mean more sinkage and more hug, which in turn means more material coming into contact with your body. As a result, softer mattresses are usually going to be warmer than medium or firm mattresses. This isn’t to say that you cannot find a soft mattress that’s also cool, you absolutely can. However, you may want to step up your budget in order to get the right combination of softness with impactful cooling features that can help manage cooling better for you.

On the other hand, firmer mattresses are usually a little cooler for the exact same reason. With a firmer mattress you usually will have a little more of a floating feel above the mattress. The mattress won’t wrap around your body or envelop and hug you in the same way that a soft mattress will. This means you have less material in contact with your body and more opportunity for air to easily flow into contact with your skin. This results in a cooler feel. As a result very firm mattresses usually don’t suffer from heat issues in the same way that softer mattresses sometimes can.

FAQs

How can I cool down my mattress?

If you’ve already done what you can to choose a cooling mattress and regulate the temperature in your bedroom, then consider new bedding. Linen sheets are great for summertime, and there are good options for breathable comforters that can help as well (check Sleepopolis for details). If you’ve tried bedding and a new mattress but don’t have air conditioning, consider putting a bowl of ice in front of a fan as a last resort.

Do latex mattresses sleep cool?

As a general rule, yes. Latex does a better job of dissipating body heat compared to other materials such as polyurethane and memory foams. Along with durability and bounce, cooling properties are one of the primary advantages of latex.

Do memory foam mattress sleep hot?

It depends. Classic memory foam is known for trapping heat, because sleepers sink into and feel enveloped by the mattress. However, many newer memory foams incorporate infusions (such as copper, gel, or graphite) to draw heat away from the sleeper and dissipate heat. If you like memory foam but are worried about sleeping hot, look for a mattress with one of these infusions to maximize your chances of staying cool.
