The Best Cooling Mattresses for Hot Sleepers
Let’s start this article off with a brief science lesson:
Every night as the time for bed draws near, our body temperature starts to drop. Through a process known as thermoregulation, body heat rises in the morning to induce alertness and starts cooling down in the late afternoon to initiate sleep.
When you are unable to cool down at night, your elevated core temperature can make it difficult to fall and remain asleep. The temperature you sleep at may be influenced by factors like climate, age, and gender, but it can also be impacted in big ways by your mattress design.
If you are a “hot sleeper” who frequently wakes during the night sweaty and uncomfortably warm, your mattress might be to blame. To achieve a deep, restful sleep as a someone who tends to sleep warm, you’ll need a mattress with a construction designed to prevent overheating.
Read on to learn about the best cooling mattress available today, and get tips and tricks for picking a bed that helps you beat the heat.
Best Cooling Mattress Reviews
To keep you cool at night, brands have unleashed a slew of new bed designs that help enhance air circulation, regulate temperature, and wick away moisture. Here are the some of the very best cooling mattresses for hot sleepers out there:
Best Overall: DreamCloud
A hybrid of latex, memory foam, and coils, the DreamCloud is a sophisticated mattress with a plush, luxury feel. Made from eight layers and standing at 15 inches tall, the mattress relies on a variety of materials and design elements to promote cooling.
The cool sleep experience of the DreamCloud starts with the cover, a hand-tufted cashmere blend that is soft and breathable. Below, a layer of gel-infused memory foam contributes comfort and temperature regulation. Underneath five layers of foam and naturally cooling latex is a five-zoned system of steel microcoils, which boosts airflow. Combined, the layers of the DreamCloud mattress work together to provide an exceptionally cool sleep experience with spinal support and pressure relief to boot.
Editor's Choice: Loom & Leaf
From the creators of Zenhaven, the Loom & Leaf defies mattress convention by sleeping exceptionally cool, despite being an all-foam bed.
To achieve a cool sleep experience, Loom & Leaf starts with a soft, breathable organic cotton cover that prevents heat retention. Beneath the cover is a gel-infused memory foam with a convoluted, egg crate-like design to promote air circulation. The layer has a panel of “Spine-Zone Gel” laminated into the lumbar area which contributes cooling in addition to lower back support.
The gel-infused layer sits above a layer of memory foam, protecting the sleeper from becoming overheated. Below that, a transition layer features channels that promote additional air circulation.
Best Value: GhostBed
At a mere $895 for a queen, the GhostBed manages to provide superior comfort and cooling at a lower price than many of its competitors. The GhostBed is constructed from latex and foam in a thoughtful layout designed to keep you cool.
The GhostBed is covered in a stretchy blend of viscose and polyester that is light and breathable. Right below the cover is a layer of aerated latex foam, a cooling material placed above the lower foam layers in order to keep you from overheating. Below, a layer of memory foam is infused with gel to help draw heat away from the body. It’s design makes it ideal for the hot sleeper looking for a high-end mattress with great cooling, support, and comfort at an affordable price.
Best Luxury: Zenhaven
Built from five layers of all-natural American Talalay latex, the Zenhaven mattress delivers all the benefits of natural latex, including bounciness, durability, eco-friendliness, and above-average cooling. The open-cell structure of Talalay latex allows for air circulation, while pinholes in the material work provide additional thermal ventilation.
The Zenhaven is wrapped in a soft, breathable cover made from organic cotton and New Zealand wool. In addition to being flame-retardant, the wool is naturally breathable and wicks away moisture to help you stay cool and dry.
Most Innovative Cooling Tech: WinkBeds
A hybrid bed, WinkBeds features an advanced coil-on-coil construction complemented by a foam-based comfort layer and base.
The mattress is covered in a soft, breathable tencel fabric with a layer of memory foam quilted in. Below, a blend of hypersoft and gel memory foams offer cooling and pressure relief. The bed features two layers of pocketed coils, allowing air to flow freely.
Though its materials contribute to a cool sleeping experience, what really sets the WinkBeds above the rest is its optional cooling base addition. First released in 2017, the coolControl Base can be added to your WinkBeds mattress to let you control the temperature during the night. The coolControl Base delivers warm or cool air up into the mattress through a network of four airflow tubes. The system includes two remote for adjusting the temperature of the bed on either side, allowing you to heat your side of the bed by up to 30 degrees or cool it down by up to -10 degrees Fahrenheit.
The best (and worst) mattress materials for cooling
Mattress construction plays a major role in temperature regulation. Here’s how the most common mattress materials handle heat, ranked from best to worst:
- Coils. Found in innerspring and hybrid mattresses, coils are slender steel springs often wrapped in a thin layer of fabric or foam. As air is allowed to circulate through coils and steel doesn’t retain your body heat, coil mattresses are among the coolest types of beds out there.
- Latex. After coils, latex is considered the next coolest mattress material. Latex foam features an open-cell structure that allows air to circulate and prevents heat from getting trapped. Non-synthetic latex, which does not conduct temperature from its environment, is particularly prized for sleeping cool.
- Gel and other infused foams. Today, you can find foam beds infused with gel, in addition to a host of other cooling materials, like graphite, copper, and aloe vera. With smart engineering, such infusions can help create a cooler sleep experience.Compared to memory foam, gel-infused foam is generally able to regulate heat more effectively. Like water, liquid gel can absorb temperature and help to draw heat away from the body. The cooling effect may be temporary, however, since there is a maximum amount of heat the gel can absorb.Other mattress manufacturers infuse foam with conductive materials like copper and graphite to promote cooling. These elements can help regulate temperature by carrying heat away from the body.
- Advanced polyfoam. Some types of “advanced polyfoam” include technologies intended to reduce heat retention. However, while advanced polyfoam may be somewhat better than traditional polyfoam at regulating temperature, we generally don’t recommend any kind of polyfoam bed to sleepers who tend to overheat at night.
- Advanced memory foam. Like advanced polyfoam, advanced memory foam may be enhanced with features designed to improve cooling, with varying degrees of success. Even with the added features, some reviewers complain of sleeping hot with mattresses made primarily of advanced memory foam.
- Basic polyfoam. Compared to conventional memory foam, basic polyfoam is usually somewhat cooler because of its lower density and open-cell construction. However, many polyfoam beds have a denser support core that contributes to a hotter sleep experience.
- Basic memory foam. When it comes to mattress materials that sleep hot, traditional memory foam is one of the worst contenders. Because memory foam contours closely to the sleeper’s body, the material may trap heat. As many as 10 percent of memory foam mattress owners complain of overheating.
How does a cover affect mattress cooling?
In addition to construction, the cover of a mattress can have a major impact on its ability to keep you cool. Today, you’ll find mattress covers of all kinds of designs and materials, but most can be broken down into one of four categories:
- Non-quilted covers. Non-quilted covers are thin and breathable. Because they are made with less material, non-quilted covers allow air to flow in and out of the mattress, resulting in a cooler sleep experience.
- Quilted covers. Found on older, traditional beds, quilted covers are thicker and can trap in more heat. Quilted covers sometimes have a slim layer of memory foam or polyfoam stitched into the fabric, which can contribute a higher degree of heat retention.
- Phase change covers. Designed to absorb or release heat depending on the temperature, phase change material (PCM) covers can be an excellent solution for both hot and cold sleepers. With this type of material, heat is absorbed until your body falls below a certain temperature, when the PCM will release heat back out. This unique technology help keep your body at a healthy temperature throughout the night.
- Cooling fabrics. As mattress manufacturers continue to get creative with cooling technologies, a variety of covers have been released in the market to help users achieve a cooler sleep. Examples of cooling materials you’ll see in cover include lycra and polyester, both of which are stretchy and moisture wicking. Another example is celliant, a thermo-reactive material that transforms body heat into infrared light that can boost oxygenation to help regulate temperature.
Mattress Firmness/Softness and Sinkage
Another mattress feature that can play a role in heat retention is its level of firmness. With a softer mattress, you are allowed to sink deeper into the surface. More mattress materials wrapping your body means less air comes into contact with your skin, which can result in a warmer sleep experience.
On the other hand, the firmer the mattress, the less you sink into the materials. Because more of your body is allowed to come in contact with the air, you are more likely to sleep cool on a firmer mattress.
That said, many soft mattresses introduce features to ensure you are kept cool at night. If you prefer a soft bed as a hot sleeper, finding a suitable soft mattress simply requires paying a bit closer attention to choosing the right design and materials.
