The Amerisleep AS3 is the most versatile model of the brand’s line. It’s a mattress designed to be breathable while allowing sleepers to choose their desired firmness level.
The construction of the Amerisleep AS3 keeps hot sleepers in mind, with a soft, breathable cover.
The top layer of the AS3 contains Bio-Pur® material. This foam is constructed with castor oil instead of petroleum oil for more breathability than traditional memory foam. It also eliminates the “new mattress smell.” The Amerisleep AS3’s HIVE® layer of foam features hexagonal cutouts to create airflow.
The AS3 offers the 100-night Amerisleep sleep trial, so you can feel comfortable ordering the mattress online and trying it out for the first time at home. If you’re unsatisfied with the AS3 within those 100 nights, you can contact Amerisleep for a full refund, and the company will donate the mattress to charity.
Amerisleep mattresses feature a 20-year warranty comprised of two separate 10-year warranties. The first offers a full replacement warranty in the first decade. The second offers a prorated refund from the original sale after ten years.
The Zoma Mattress was made to help you reach the deeper stages of sleep for improved muscle recovery. It has a medium feel suited for side and combo sleepers.
The top 2-inch layer of gel memory foam absorbs and disperses body heat. You also keep cool with the layer’s Triangulex™ technology–it’s triangle-shaped cutouts not only soften the areas under your legs and shoulders but make it easier for air to flow through the mattress.
Below is a 2-inch layer of latex-like Reactiv™ to improve the bed’s responsiveness, preventing you from feeling “stuck” in your mattress. At the bottom is 7 inches of Support+ foam to deter sagging.
The breathable cover has a blend of polyester and spandex that stretches for air to flow through and wick away heat.
A Zoma Mattress comes with a 100-night sleep trial, so there’s no need to worry about buying the mattress sight unseen. If you find yourself dissatisfied by the Zoma Mattress, a local charity or recycling service will pick up your mattress, and you will receive a full refund.
Each Zoma Mattress includes a 10-warranty that protects against sagging deeper than 0.75 of an inch. Sagging compromises a mattress’s support—the more it sags, the more it may cause sleep disturbances and back pain.
The Vaya Mattress provides the perfect blend of support and pressure relief while keeping cool throughout the night. It contains two layers of light polyurethane foams, to keep the bed simple and affordable.
The comfort layer is 3 inches of Vaya Foam, which molds itself to your body while wicking away warm air. It has a lower density than traditional memory foam, and while bouncy, the foam still cancels out movement.
The support layer is 9 inches of high-density foam, adding back support and durability to the mattress.
The soft cover is a breathable mix of rayon, spandex, and polyester, with a weave designed to increase airflow.
You can find the Vaya Mattress on Amazon. The mattress comes with a 100-night sleep trial and a 10-year warranty that protects against sagging greater than 0.75 inches.
If you’re a back sleeper looking for a firm, strong mattress offering support as well as cooling, try the Bear memory foam mattress.
The Bear combines pressure point support and the comfort of memory foam with the strong backing of a traditional innerspring. It also features a graphite infusion in its memory foam to help maintain coolness.
Each Bear mattress starts with a Celliant® cover, a material that studies have found can promote body recovery during sleep.
The top layer is two inches of memory foam offering pressure relief and comfort combined with a graphite infusion. This layer helps prevent overheating found in many memory foam mattresses. The transition layer is a strong poly-foam designed to avoid sinking. The base is six inches of high-density poly-foam.
Bear offers buyers a 100-night sleep trial with a full refund after a standard 30-day trial period. There’s also a 10-year limited warranty covering physical or construction flaws or any sagging of one inch or more.
Side sleepers need a particular kind of support. This is where Nolah comes in, as its mattress is designed to provide great support for any sleeping position. The thicker comfort layer helps relieve pressure point issues common among side sleepers. If you’re a hot sleeper who sleeps on your side, Nolah’s temperature neutral mattress is perfect for you.
The 10-inch Nolah mattress is covered with a blend of polyester and viscose created to provide a thin, breathable layer. The first layer is the cushy two inches of a proprietary “AirFoam” claiming to relieve pressure point areas better than standard memory foam. Below the AirFoam is an inch of Avena foam, which imitates latex. Below is a 7-inch support layer made of high-density base foam.
Each standard Nolah mattress comes with a basic 15-year warranty offering replacement for defective construction or materials. The signature Nolah mattress (the thicker 12-inch model) features a lifetime warranty with a repair policy to the standard 15-year warranty.
Nolah also offers a 120-night sleep trial period for buyers. After a 30-day trial period and up to 120 nights from the original delivery date, a buyer can return a Nolah mattress. The company will pick it up at no cost and offer a full refund.
Muse offers a softer, lighter sleep for those who are more lightweight. If you’re a side sleeper or just someone who prefers to have a mattress top conform to your body shape, check out Muse. It’s an all-foam mattress but without the heat. It’s available in a variety of models with different firmness levels—soft, medium, and firm.
The Muse mattress starts with a cover made of phase-change material created to help contour to the body. Underneath is a gel-infused memory foam layer designed to avoid the heat absorption most memory foam layers feature. There’s also an 8-inch base to provide firmness and prevent sinking with additional edge support. Muse also emphasizes motion isolation in its construction. This means body movement won’t create a disturbance when sharing a bed. The base layer features a removable cover for easy cleaning.
The Muse mattress comes with a 120-night sleep trial. If you’re dissatisfied after the initial 30-day trial window, you can ask for a refund. There’s a standard 10-year warranty for any flaws or damage incurred from assembly or materials. The Muse warranty defines replaceable sagging as just ¾ of an inch, a smaller measurement than many mattress warranties.
If you need a mattress with cooling technology to support a larger body, check out the Revel Hybrid. The Revel is a thicker mattress with enough weight to provide extra support and stay in place. It also won’t overheat sleepers.
The Revel Hybrid measures 12 inches thick and features three main layers of foam. The first layer is memory foam combined with a cooling gel. This layer takes care of pressure relief and helps contour the body while also getting rid of excess heat created by your body. Revel can be found exclusively on Amazon if you’re thinking about trying one out.
The second foam layer is designed to imitate latex, specifically known as “LiftTex.” Revel claims this layer has the responsiveness of a typical latex layer. It has airflow channels cut into the layer to provide extra ventilation and cooling. There’s still another 7-inch base layer bigger than some entire mattresses on the market today. The base layer provides the bulk of the support and creates a sturdy base to avoid moving or shifting.
Revel features a standard, non-prorated 10-year warranty with a full refund for damage related to construction or materials. But there’s a much shorter trial period. Unlike most mattress companies who offer 100- or even 120-night sleep trials, Revel has a 30-day window for users to return the mattress for a full refund via Amazon.
8. Original Purple®
Purple’s® “temperature neutral” feature offers a great mattress for hot sleepers. The mattress’s unique construction helps to both absorb and dissipate heat from your body while providing excellent support and comfort.
The Original Purple® mattress measures almost 10 inches and features three specific layers. The top layer is Purple’s® innovative Purple Grid™ designed to provide comfort and prevent heat retention. This grid contours to your body’s shape by collapsing around it while also retaining enough strength to support your hips and back.
Underneath the comfort layer is 3.25 inches of poly-foam and 4 inches of higher-density poly-foam as a base. The mattress is covered with a blend of Lycra and polyester, which is soft and durable but not as breathable as organic material.
Purple offers a generous 120-night sleep trial. If you aren’t satisfied after the requisite 30-day sleep trial period for new customers, Purple will refund your cost in full. There’s also a 10-year warranty on each Purple mattress protecting against any manufacturing defects, cracking or splitting of materials, and sagging up to one inch.
Best Cooling Mattress Types to Consider
If you’re a hot sleeper looking for the best cooling mattress available, you’ll need to familiarize yourself with the types of mattresses available on the market. The best mattress for hot sleepers can be found in any of the following varieties.
Memory Foam Mattresses
Memory foam mattresses are very popular with modern sleepers and have become associated with mattress-in-a-box sales. The problem for hot sleepers, especially those suffering from night sweats, is the fact that cheap memory foam can create overheating and prevent air circulation. If you’re looking for a comfortable sleep, avoid cheap memory foam beds.
Latex mattresses can be a great choice as the best mattress for hot sleepers if you pay attention to the materials used. Natural materials, such as rubber tree sap, must be used for a mattress to be considered latex. The best latex mattresses offer a temperature neutral sleep thanks to their natural materials. Synthetic materials such as polyester don’t allow for air to move as easily between their fibers, creating less airflow. Because of this, heat can be trapped more easily by a synthetic material.
The traditional spring mattresses are still among the best at avoiding heat retention. Innerspring coils are hollow and metal, so they allow for seamless airflow through the mattress. It’s a traditional cooling technology, but it works great for hot sleepers. When you’re looking at innerspring mattresses for cool sleeping, be sure to consider those with individually pocketed coils. These allow for better air transfer.
Hybrid mattresses are a combination of memory foam and innerspring. Combined with comfort layers built with gel memory foam on the sleeping surface, innersprings are often the coolest beds available on the market. Hybrid mattresses also come in a variety of builds and firmness layers. This allows for many levels of support in addition to a cool sleep.
Finding the best cooling mattress can be tricky if you don’t set a budget. Once you know your sleeping style and preferred mattress type, you’ll need to look for beds in your price range. Top picks for a particular mattress style might not always match up with what you can afford.
There are a variety of affordable new mattresses for you to consider, but they aren’t dirt cheap. Keep in mind when looking for the best cooling mattress, you should budget at least $500. This is likely the minimum you would pay. The average price for mattresses featuring cooling technology is often close to $1,000.
Cheap mattresses, especially those made of memory foam, often create overheating. Why? Lack of airflow. Sure, innerspring mattresses are cooler because of the natural airflow of coils. But the quality of bargain innerspring mattresses can decrease quickly, creating “sagging” in the coils. In the long-term, this won’t help you.
While you might be searching for the best mattress for hot sleepers, you should also consider your sleeping style when searching for a new mattress. Depending on how you spend most of the night asleep, you might have to adjust your purchase. Different sleep styles require different kinds of mattresses specializing in support for particular areas of your body. To maintain good health, choosing the right kind of mattress is key.
Side sleepers can consider a variety of mattresses. Especially if you sleep on one side with your legs either straight or brought closer to your body in the fetal position. But the best mattresses for side sleepers are usually memory foam because of its contouring effects and pressure point support.
Back sleepers are often in search of firmer support when searching through mattress brands. As back sleepers often struggle with sleep apnea and snoring, an adjustable bed can provide elevation for the head and chest.
Stomach sleeping can be harmful over time, as the position creates stress on the spine. It can also cause restlessness and pain. Stomach sleepers often prefer firmer surfaces and search out mattresses with minimal motion transfer.
Sleeping Cool and Airflow
When shopping for the best cooling mattress, be sure to explore the specific cooling technology each mattress offers. Take advantage of different sleep night trials from mattress companies. You might find you prefer certain cooling technologies more than others.
Airflow is very important for sleepers worried about a mattress’s heat retention. Because of this, a great option is a hybrid or plain innerspring mattress featuring coils as a support layer instead of just memory foam. Why? Memory foam has a harder time releasing heat. Yet many memory foam beds feature advanced technology to absorb and remove heat from sleepers.
There’s also a variety of accessories that can assist the cooling process for a better night’s sleep. Cooling sheets are either made from organic, breathable materials or sheets specifically designed to cool your mattress. Pillows made of breathable, natural materials like latex will also retain less heat as you sleep.
Why do I generate so much heat while I sleep?
Your body temperature lowers while you sleep, so if you’re waking up hotter than usual, it’s because of your sleep environment. Using the wrong kind of blankets (or just too many) can trap too much of the heat your body emits. Unless you’re suffering from a medical condition or running a fever, it’s not your body producing the heat—it’s your sleep environment.
How do you cool down a hot mattress?
If you’re trying to sleep cooler without purchasing a new mattress, there are options to cool down your sleep with your current bed. First, check your bedding and room temperature (see below). Once you’ve done that, if you still need to sleep cooler, you can purchase special mattress pads or toppers with cooling gel. This will help trap heat and move it away from your body as you sleep.
How can I keep my bed cool at night?
There’s a variety of ways to keep your bed from overheating while you sleep. To start, make sure you’re using a natural, breathable fabric for your sheets. Cotton works best, but you can choose any natural fiber allowing for air to move through the fabric. Be sure to avoid polyester or satin sheets if you’re trying to stay cool. Also, make sure whatever you wear to bed is made from natural fibers. And be sure those pajamas aren’t tight. Loose-fitting clothes “breathe” better.
You can also prepare your room—and your body—for a cooler night’s sleep. Use a fan as well as central air conditioning to create more airflow in your bedroom. The lower your bed is to the floor, the less heat you’ll feel in the air since heat rises. Before you go to bed, avoid eating a heavy meal. When you consume a large meal, your body requires more energy to digest, which in turn creates more heat.
You should also drink a little water before you go to sleep to avoid dehydration, which can raise your body temperature. You don’t want to wake up in the middle of the night to use the bathroom, so don’t drink too much. Still, proper hydration helps the body cool itself.
What is the ideal temperature for sleeping at night?
As your body drifts off to sleep, your body temperature gradually decreases. The body does this as a way of shutting down certain functions. This process makes it easier to fall asleep in a cooler room than a warmer one. While everyone’s preferences for room temperature is different, it’s advisable to keep your thermostat between 60 and 67 degrees Fahrenheit. The chill will help you fall asleep more easily and stay asleep longer.
The Best Cooling Mattress Depends on Your Taste, Sleeping Style, and Budget
To find the best cooling mattress and prevent overheating, you’ll need to consider many factors: budget, sleeping style, mattress style preference, and your sleep environment. Now that you know what to look for in a cooling mattress, the only question is which one will you choose?
