Updated July 9, 2020People who sleep hot need breathable mattresses with cooling technologies to regulate their body’s temperature. Some mattress materials, like poly-foam and memory foam, will absorb body heat, causing the sleeper discomfort and sleep disruptions. Other materials, like cotton and gel memory foam, wick away heat and moisture, allowing for better sleep.In this article, we recommend cooling mattresses and discuss why people overheat in their sleep. We will also explore how to select the best cooling mattress by looking for breathable materials and other cooling features.Best Cooling Memory Foam Mattress for Hot SleepersMattressHighlightPriceAmerisleep AS3Bio-Pur® and HIVE® technology increase air circulation through the mattress.$1199Zoma MattressGel memory foam and Triangulex™ technology improve airflow through the layer.$750Vaya MattressVaya Foam increases air circulation to prevent heat retention.$540Muse BedPhase-changing cover regulates temperature and increases airflow for cooler sleep.$950Bear MattressGraphite and gel-infused memory foam keep you cool by wicking away heat.$650Nest Bedding Alexander Signature Series® FlippableBreathable CoolFlow™ Foam increases your comfort by conforming to your body.$15991.

If you sleep with insulative materials, body heat can become trapped, causing you to overheat. You can avoid overheating if you sleep with breathable materials and fewer layers.Why Do Mattresses Become Hot?Two factors impact a mattress’s ability to circulate air and keep the sleeper cool: the mattress’s firmness and the sleeper’s body weight.FirmnessFirmness refers to how soft or firm the mattress’s sleep surface feels. We rate bed firmness as soft, medium-soft, medium, medium-firm, or firm. Choosing the right firmness can improve your sleep quality; however, it’s not an exact science. Your personal preferences and sleep position can help you estimate which firmness level is best for you.Side sleepers need a soft, medium-soft, or medium mattress to alleviate pressure points and avoid chronic pain.Back sleepers need a medium to medium-firm mattress to maintain spinal alignment.Stomach sleepers need a medium-firm to firm mattress to limit back stress and encourage correct spinal alignment.When soft mattresses compress, air circulation is cut off, leaving heat to build up. Firm mattresses don’t conform as deeply as soft beds, so air can travel through the mattress and wick away heat more easily than soft beds.Body TypeHeavier people emit more body heat and place more pressure on a bed’s surface than lighter people. The further an individual sinks into the mattress, the more materials wrap around the body, increasing the risk of trapping heat. Plus-size people also use more energy than smaller people to move, increasing body temperature.What is a Cooling Memory Foam Mattress?A cooling memory foam mattress actively cools you down by pulling heat from your body, encouraging airflow, or both.Some manufacturers incorporate materials to wick away heat from the sleeper. Other mattresses contain materials to promote air circulation.Aerated foams have small holes built into the foam to promote air circulation and wick away heat.Cooling gel, copper, graphite, and titanium are conductive materials often infused with memory foam. Conductive materials pull heat from the body, allowing people to sleep cool.The best mattresses contain both special textiles and conductive infusions to encourage enough airflow to offer a very cool sleeping experience.Cooling Mattress MaterialsSome mattress types are cooler than others. Cool mattresses are made with breathable material or technologies, while hot mattresses tend to retain body heat.Memory Foam MattressA memory foam mattress is generally made with a memory foam comfort layer, poly-foam transition layer, and poly-foam support layer. Memory foam has a porous structure, so air can circulate through the foam particles. Mattress companies aerate memory foam to increase air circulation. Other times, mattress manufacturers add conductive material infusions to pull heat from the sleeper.If you overheat during sleep, you may consider including aerated foams and conductive materials in your new mattress.Hybrid MattressHybrid mattresses are constructed with pocketed coil systems and at least 2 inches of memory or latex. This type of mattress relieves pressure by conforming to your body. Hybrids also isolate motion, so you can get out of bed without disturbing your sleep partner.Pocketed coils are coils wrapped in fabric. The support system has space between the coils, allowing air to circulate through the mattress and wicking away heat; however, thick transition and comfort layers may decrease the mattress’s breathability.Innerspring MattressInnerspring beds, or traditional mattresses, have coil support systems. Some innerspring mattresses are built with Euro or pillow tops—these extra comfort layers can increase heat retention if made with non-breathable materials. Look for natural fibers if you want a breathable pillow top.Latex MattressThere are several types of latex: natural, blended, synthetic.Natural latex is manufactured in one of two ways. The Dunlop process produces a dense, firm latex foam with antimicrobial and hypoallergenic properties. Talalay latex also has antimicrobial and hypoallergenic properties; however, the Talalay process produces a light and springy latex.Synthetic latex is made with a chemical compound to mimic latex properties. Synthetic latex is hypoallergenic and safe for latex allergy sufferers but does not have antimicrobial qualities. We don’t recommend buying latex mattresses with synthetic latex as the material may contain chemical additives. If you decide to buy a synthetic latex mattress, make sure the materials are CertiPUR-US® certified.Blended latex is a combination of natural and synthetic latex. It has some antimicrobial properties.Latex is a breathable material. Its porous structure allows air to flow through the foam instead of trapping heat.The Mattress CoverThick, quilted, or non-breathable covers insulate the mattress, raising the risk of heat retention. A thin, breathable mattress cover keeps you cool by increasing air circulation through the mattress.Phase-change materials: Phase-change materials are cool-to-the-touch. The material absorbs body heat and then releases it when your body becomes cold, allowing your body temperature to remain consistent.Breathable fabrics: Covers made from breathable materials increase the mattress’s ability to circulate air. Many online mattress brands use covers made from Lycra®, bamboo, cotton, Tencel®, and performance polyester as these materials encourage airflow.Non-quilted covers: Quilted covers retain heat because the material is compressed together. Non-quilted cover encourages airflow through the material, which increases the mattress’s ability to keep the sleeper cool.Bedding AccessoriesIf you don’t have the budget to buy a new mattress with cooling features, there are other ways to decrease heat retention in your mattress.Bed SheetsJust like the mattress cover, non-breathable bed sheets can trap heat. We suggest using a set of natural fiber bed sheets as these materials are more breathable than man-made fabrics.Bed sheets made with long-staple cotton and linen threads are very cool. Tencel® and bamboo are cool to the touch, making them great cooling options.Synthetic fibers are not as breathable as natural fibers. Synthetic bed sheets insulate warm temperatures and prevent air from circulating, so they’re a bad choice for hot sleepers.Gel Mattress ToppersIf your mattress is hot, you can try a gel memory foam topper. A gel memory foam topper acts as a cooling barrier between you and the mattress. The gel infusion wicks away body heat, so your temperature remains constant.If you’re experiencing joint or muscle soreness, you may also consider a topper to adjust your mattress’s firmness. You can make a firm mattress softer or a soft bed firmer.Cooling PillowsPillows can retain heat if they don’t contain breathable or cooling materials.Loose-fill pillows (feather, down, shredded memory foam, and buckwheat) encourage air circulation to cut down on heat retention; however, if you want a solid memory foam or latex pillow, we recommend aerated foams or conductive material infusions to keep a cool head.Other Things to ConsiderDo memory foam mattresses sleep hot?According to Sleep Like the Dead, only 8 percent of memory foam mattress owners say they overheat on their memory foam mattress. If you’re considering a new memory foam mattress, look for cooling technologies and aerated foam to ensure undisturbed sleep.Can you flip a memory foam mattress?You should not have to flip a memory foam mattress, although it may need rotating. See the manufacturer’s care tag to learn how to care for your mattress correctly.How do you cool down a memory foam mattress?Even if your mattress doesn’t contain any cooling technologies, there are still ways to get cooler sleep. We suggest adding a cooling mattress topper to serve as a breathable layer between your body and the bed. We also recommend buying breathable sheets, like cotton or Tencel®, to prevent heat from being trapped within your bedding.Lastly, turning down the thermostat helps, too. If you prefer your home or apartment to be warmer during the day, just crank the heat down at night to enjoy cooler sleep until morning. Then, you can adjust the thermostat back in the AM.What mattress is best for hot sleepers?There are plenty of mattresses designed for hot sleepers, but many of the best mattresses for hot sleepers contain both cooling technologies (i.e. cooling gels, latex, or plant-based foams) and aerated channels to promote better airflow. Foam beds with these channels are a good option, or hybrids with an open pocketed coil system are great, too. Don’t forget to check the materials of a mattress’s cover, too. Look for breathable fabrics like cotton and avoid synthetics like microfiber.Why does my mattress get so hot?Most people struggle with foam mattresses retaining heat, while beds with coils generally have better airflow. Foam mattresses can become a heat trap because they absorb your body heat throughout the night and, if this body heat cannot escape the bed, it’s reflected back at you.ConclusionThe best cooling mattress for hot sleepers is constructed with materials that both encourage airflow and pull heat from the sleeper. Look for memory foam mattresses with air passages or conductive materials. If you have a memory foam mattress that sleeps hot, try placing a gel memory foam topper on top to create a breathable barrier between you and the bed.This article is for informational purposes and should not replace advice from your doctor or other medical professional.
