Sleeping in a nice, warm bed is awesome. Waking all hot and sweaty – not so much. Our body slightly lowers its temperature while sleeping, and having an ambient temperature of around 60-67 degrees should work wonders. However, your mattress, sheets, bedding material is absorbing heat and can pump up the temperature to uncomfortable levels. That usually results in you waking up hot and sweaty, necessitating the need to find the best mattress for cool sleeping. A big part of this problem can be solved by using a mattress that dissipates heat. Thankfully, modern technology has provided us with the best cooling mattress solutions that work beautifully. Let’s have a look!
4 Best Cooling Mattresses
The secret of cooling (and name) of the Purple Mattress is the purple-colored hyperelastic polymer that forms that forms the top layer of this mattress. Arranged in the form of a grid, the hyperelastic polymer creates air pockets that make Purple a top contender as best mattress for cool sleeping.
Of course, the grid does more than just keeping the mattress cool. It collapses under higher weight to keep the spine aligned, and offers greater pressure relief. Since the polymer can keep pressure localized, it’s also great for motion isolation. The hyperelastic polymer works remarkably well for almost all sleep preferences and weights.
Following the hyperelastic polymer grid is a layer of 3.5-inches of foam that works both as a comfort and transition layer, leading to 4-inches of high-density polyurethane support foam at the bottom. The total height of the Purple mattress is 9.5-inches.

Layla takes an interesting approach by bringing in copper-infused cooling for its memory foam mattress. A frontrunner for copper-infused cooling for mattresses, Layla tries to be the coolest mattress to sleep on. To aid copper infused cooling, tiny wires run through the memory foam layer, using the conductivity of copper to distribute and whisk away extra heat.
Layla mattress doubles up on cooling efforts with a thermogel infused cover that further helps draw out heat, and helps keep the sleeper cool. The mattress is flippable, offering different firmness options for both sides. Inside the thermogel infused cover, the layers are arranged as 3-inch copper-infused memory foam, 2-inch support foam, 4.5-inch base support foam, and finally, 1-inch of copper-infused memory foam.

Even as a budget option, the Dreamfoam Bedding Arctic Dreams is a very well constructed mattress. If we were to go by simple cool memory foam mattress reviews, the Arctic Dreams does a better job as a cool tempurpedic mattress than several premium, higher priced options.
The mattress has a 0.75-inch quilting layer, followed by 2.5-inch fast response Energex Gel Memory Foam, and finally, 7.5-inch foam support layer.
As you can guess, the Energex Gel memory foam is the primary element for this mattress. According to the manufacturer, this layer gives the mattress a faster response than conventional memory foam, while also increasing its ability to dissipate heat. Perhaps the greatest factor in favor of the Dreamfoam Bedding Arctic Dreams is the large number of best cooling mattress reviews it has received from consumers.

The Muse Mattress deals with heating issues by taking its mattress cooling solutions to the memory foam as well as the covers. Cooling efforts for the Muse mattress start with the cover itself, which is made from a special fabric, according to the manufacturer. The fabric uses Diamond Breeze Yarns to wick away heat, and its “Phase Change” fabric absorbs heat to keep things temperature neutral. While we’re not usually given to marketing buzzwords, The Muse actually feels cool to the touch so they are doing something right.
Following the fabric is a layer of gel-infused memory foam that works in conjunction with the cover to keep the sleeper cool. Overall, yes, The Muse does make a fairly interesting cooling mattress. The mattress is available in soft, medium, and firm versions, each with the cooling technology that makes the 12-inch Muse one of the best cooling mattresses to pick.

Basics of the Best Cooling Mattress
Now that we’ve seen the best cooling mattresses 2018 has to offer, let’s see what factors affect sleeping hot, and how mattresses deal with it.
Effects Of Mattress Construction And Materials On Cooling
Coils and Springs
Coils and springs form the basics of the traditional innerspring mattresses, as well as most hybrid mattresses. For a majority of mattresses, coils form the support layer with foam forming the comfort layers. Coils may be individually encased or connected. In any case, they leave a fair amount of room for air to circulate, and as a result usually sleep cooler than their counterparts. Larger the coil component of a mattress, more is the room for air circulation and temperature regulation, and so more is the likelihood of the mattress staying temperature neutral.
Latex/ Latex Foam
All-natural latex sourced from rubber trees is hypoallergenic, durable, and breathable. Synthetic latex has similar qualities and depending on the manufacturing process, can have a fair bit of aeration, though usually lower than natural latex. Most latex mattresses are made from a blend of synthetic and natural latex. In any case, even with small cooling efforts, latex can be temperature neutral.
One of the most popular materials in mattress comfort layers, memory foam is well-regarded for the pressure relief it offers. As the foam takes on pressure and body heat, it contours to the shape of the body and creates a great feel for the sleeper. Since basic memory foam does require heat for it to function, it unfortunately also traps heat. Memory foam mattresses are one of the worst offenders when it comes to sleeping hot, and as our list shows, are also the ones that need special consideration and cooling efforts.
Mattress manufacturers have tried to address the issue by the use of technologies like gel-infused foam, or diamond, graphite, bamboo, or copper infused foams, among others. While the results may vary, you can always take extra measures to cool down your memory foam mattress.
Bamboo mattresses have considerably increased in popularity in the last few years. The material is breathable, gentle, and its fibers can quickly wick away heat and sweat/moisture before it becomes a problem for the sleeper. A durable and naturally sourced product, bamboo is often used along with memory foam to help it stay cooler.
Polyfoam/ Advanced Polyfoam
Polyfoam is often used as a transition or support layer in mattresses, though it does find application in comfort layer of some mattresses as well. Polyfoam generally sleeps hotter than latex but cooler than memory foam. Although it also lacks the contouring and conforming properties of both materials. Advanced polyfoam fares better in temperature regulation thanks to a better open-cell structure to move air.
Best Cooling Mattress — How Covers Play A Big Role
As you may have noticed, a lot of mattresses sing praises of their covers on account of temperature regulation. As the part directly in contact with the sleeper, the cover indeed has a big role to play. Here’s how the four major covers deal with sleeping hot:
Quilted covers are appealing to those who want a traditional look, and perhaps a softer touch for the bed. Addition of materials obviously can increase the possibility of sleeping hot, so check the materials used to ensure they can provide thermal regulation.
Simpler, thinner, and usually cheaper than their quilted counterparts, non-quilted covers are increasingly used to create the coolest mattress to sleep on. There isn’t a lot of material getting in the way of air circulation, and with a good construction, these covers can be helpful in wicking away sweat or dispersing heat.
Phase Change Materials (PCMs)
PCMs are great at temperature regulation. The materials are designed to absorb body heat up to a certain temperature, after which they distribute the heat throughout the mattress/cover to keep the sleeper at a better, more suitable temperature.
Just like the use of cooling materials in foam, many companies also extend use of cooling materials to fabrics of covers. Specialized fabrics are often used, the most common ones being Celliant, Lyocell, and Lycra Spandex.
