Top of the line cooling technology
If staying cool at night is one of your main concerns, why not get a mattress that was specifically designed to do just that? The Cocoon is Sealy’s take on a bed-in-a-box mattress, and it’s the perfect budget option for hot sleepers who like the feel of a memory foam mattress. Our editor’s pick on this list, the Cocoon accommodates all sleeping positions, and offers cushioning for the body as you move throughout the night. Best of all, the Cocoon Chill comes in a variety of firmness levels, so those who prefer a softer mattress or a firmer mattress should find a great match.
Loren, our wonderful editor and certified sleep science coach, says, “This bed is great for people who tend to sleep warm because there are a lot of breathable layers that allow airflow, so your body heat has somewhere to escape.” Watch Loren’s full review of our editor’s pick below.

The Helix Midnight is our pick for hot side sleepers seeking pressure relief and cooling comfort.
Luxury zoned support made for side sleepers
The Helix Midnight Luxe is a great option if you want a mattress that combines the “hugging” comfort of foam with the support and airflow of individually wrapped coils. In the Helix Midnight Luxe, memory foam is coupled with coils that keep air moving through the mattress at night. The result? Heat is whisked away from the body and hot sleepers stay cool thanks to the extra air circulation.
The Helix Sleep brand sells 14 different mattress models made specifically for different sleep positions. The Helix Midnight Luxe is specifically designed for side sleepers. It features memory foam that provides targeted support for the hips, shoulders and neck to keep the spine aligned and prevent stiffness.

Often referred to as “affordable luxury,” the Saatva Classic mattress creates a luxurious hotel-bed feel and delivers it straight to your doorstep.
Plush Soft, Luxury Firm, Firm
High quality and custom firmness options
The Saatva Mattress is one of our favorite beds here at Mattress Nerd. The robust support core of individually wrapped coils promotes airflow through the entire bed, and Saatva also uses eco-friendly organic cotton in its topper, which is known for its cooling properties and for furthering the airflow to the sleeper’s body.
This hybrid mattress combines the coil base of a traditional innerspring mattress with a euro-pillow top sewn into the top of the mattress, which offers best in class comfort and back support for those with lumbar problems. The Saatva Classic is also a great option for couples, especially because of the reinforced edge support and decent motion isolation. You will definitely have room to spread out and use the entire surface of the bed, but if you have a partner who moves a lot throughout the night you may feel a little bounce now and then.

Top-of-the-line cooling technology
You and your sleep partner in the market for a new mattress that will keep you cool all night long? The GhostBed Luxe would be our top choice for you. This bed is constructed of four foam layers, the top two of which contribute to its compatibility with couples and hot sleepers.
While the top Ghost Ice Layer ensures that little heat gets trapped in the foam, the Ghost Memory Foam layer provides the motion isolation that will keep you from feeling all of your partner’s little movements throughout the night. Another bonus for couples is the Luxe’s firmness level: it comes in at a 5/10, meaning it is halfway between soft and firm on the mattress firmness scale. Medium-firmness tends to be well-suited for just about any sleeper, so all parties involved should be satisfied.

The Bear Hybrid mattress captures all the most coveted features in a mattress and jam packs them into this state-of-the-art hybrid. The cooling gel memory foam continuously carries away heat, promising a cooler, more restful night of sleep.
Superior support and alignment
The Bear Hybrid’s premium foam and individually wrapped coils provide sleepers with support and pressure-point relief while adapting to the body’s unique shape. The hyper-soft cooling gel foam is also a major plus for hot sleepers, as gel-infused memory foam is one of the best ways to help foster a cool night of sleep. Bear also uses certified eco-friendly materials and a water-based bonding solution to ensure minimal impact on the environment.
This mattress comes in at a 6 on our firmness scale of 1 to 10. This medium-firm feel makes it ideal for side and back sleepers who prefer a mattress that will provide optimal spinal alignment. Its five support layers work to address each of the pressure points that normally plague these types of sleepers, and the individually wrapped coils promote breathability and airflow. The Bear Hybrid is also a good option for couples because of this pocketed coil system, which reduces motion transfer and provides excellent edge support.

Great for most everyone! Excellent all-around mattress.
Handcrafted and made-to-order in the U.S., the Leesa Hybrid is a medium-firm luxury mattress. It includes three layers of dense memory foam that make this bed ideal for back, stomach and side sleepers. The foam layers provide added support and spinal alignment, and when combined with the innerspring coils, the Leesa can adapt to all sleeping styles and body types—even heavy sleepers who tend to sleep hot.
As to the feel of this mattress, the Leesa Hybrid features premium foam that’s bouncier than traditional memory foam. This new material lends a balanced foam feel, unlike slow-moving, classic memory foam, which tends to sleep hot and make sleepers feel “trapped” in their mattress. The Leesa’s premium foam and 6” layer of breathable innerspring coils combine to chill the mattress down for a cool night’s sleep.

A lot of mattress for the money
The Nectar Lush mattress is best suited for side sleepers and sleepers who love the hug of memory foam. This medium-firm mattress combines cradling for pressure relief with support for back sleepers, all at a competitive price. The Nectar Lush is an all-foam mattress, so it excels in pressure relief and minimizing motion transfer, which makes it an excellent option for couples.
Still, if you are a heavier sleeper, a stomach sleeper, or both, the Nectar Lush will likely be too soft for you. It simply doesn’t include the supportive coils that help keep the body elevated in stomach sleepers. The Nectar Lush comes with a Lifetime warranty and a 365-day trial period: two very attractive policies for hesitant shoppers.

Breathability & Support
If you have your heart set on a mattress with superior cooling abilities but can’t decide on a firmness level, you might consider a flippable mattress, our favorite of which is the Layla Hybrid. With one side having a soft feel (3/10) and the other having a medium-firm feel (6.5/10), it allows sleepers to adjust their sleep experience on a whim—all you need to do is flip it!
Being a hybrid, the Layla has a lot else going for it, as well. The layer of individually wrapped coils creates structure and allows for better responsiveness to your movement, and the memory foam stifles motion transfer, which should keep couples sleeping soundly. We’d recommend the firmer side for heavy and average sleepers, while lighter-than-average folks will likely find the soft side better suited for them.

The Brooklyn Aurora is a luxury hybrid mattress that helps regulate temperature and keep you cool all night long.
Cooling features and overall comfort
The Brooklyn Aurora mattress, from the online mattress company Brooklyn Bedding, helps keep hot sleepers comfortable with its TitanCool™ technology. TitanCool is a phase change material that helps moderate body temperature, using gel beads that react as your body heat rises to cool you down.
Because it’s offered at three firmness levels, the Brooklyn Aurora has a hybrid option for most types of sleepers. Side sleepers will like the soft option, which provides pressure point relief and support for the body’s contours. Back and stomach sleepers should choose the firm option for lumbar support and a flatter surface. Combination sleepers are best suited for the medium option, which offers a fantastic balance between contouring and support. Medium firmness is also a great option for couples who have different sleeping preferences.

A versatile and breathable bed available in hybrid and all-foam models.
Amerisleep makes a variety of mattresses designed to suit all types of sleep positions. Its best-selling model, the all-foam AS3, is the middle firmness option, meaning it accommodates the widest variety of sleepers. It was designed to be a comfortable bed for all people of all sleeping positions, weights and pain concerns, and in our experience, it gets pretty close.
The AS3’s cover is crafted with Celliant technology, which is designed to promote recovery and converts body heat into infrared energy and transmit it back to the body. It may also help improve tissue oxygenation, boost blood flow and regulate body temperature. The mattress has a feel that’s comfortable and supportive, providing close conforming and spinal support. The thick memory foam comfort layer cradles the body and allows sleepers to feel like they are sleeping “in” the mattress rather than “on” it. As far as memory foam mattresses go, we’re really impressed with the cooling capabilities in the Amerisleep AS3.

Construction is everything when it comes to picking a great new mattress. Not all beds are created equal when it comes to cooling, and when the bed is constructed with the right materials, you’ll be set up for success. Below we’ve listed a few of our favorite mattress materials that enhance cooling and keep you comfortable.
Latex is one of the best materials available for keeping hot sleepers cool. It is naturally breathable and allows air to circulate far better than other types of materials, like memory foam. Because of its open-cell construction, latex allows for proper ventilation and wicks away heat and moisture.
The best latex mattresses incorporate innerspring coils and a thick comfort layer of latex for a breathable, responsive feel.
While once considered a nightmare for hot sleepers because of how it tends to trap heat, memory foam has come a long way as far as cooling technology goes. While you are still more likely to get a cooler night’s sleep on another mattress type, if you are set on a memory foam bed, you can still find a great cooling bed. Several mattress companies have started infusing their foams with copper, using open-cell technology and using gel-infusion to offer a great deal of temperature regulation, in addition to cloud-like comfort.
If cool sleeping is your primary concern, you can’t go wrong with an innerspring mattress. With innerspring mattresses, air moves freely between the coils, and there is far more room for airflow than with a foam mattress.
Hybrid mattresses give hot sleepers the airflow of a traditional innerspring, combined with the comfort of a memory foam layer. Since hybrids are known as good options for hot sleepers, many of the memory foam comfort layers include cooling technology like gel or charcoal infusions to increase temperature regulation.
Mattresses can certainly make a difference to those who sleep hot, but not all mattresses do this job equally. It’s simple: If the material in a mattress does not allow air to circulate away from the body, hot air will stay trapped inside and cool air will stay out. Air must be able to flow freely within the mattress to regulate temperature.
One way to help ensure you are getting a breathable mattress is to read about its construction. What are the layers made of? What type of foam is used? How is cooling technology incorporated in the cover? Any mattress company can claim that they manufacture a breathable memory foam mattress, but if the inside is just a solid block of foam, it’s probably not going to effectively cool the body.
Shoppers set on a temperature-neutral bed should look for “open cell” and “gel-infused” memory foam when shopping. You should also be sure to always read the reviews to see how other hot sleepers experienced the mattress. That way, you’ll be as well-equipped as possible to find a mattress that truly keeps you cool.
Speaking of cooling technology, most of the leading mattress companies (certainly all the ones we’ve mentioned in this post) have incorporated cooling technology into their mattress designs. Many have even made new editions to previous models as they create new scientific advances in the cooling ability of their mattress.
What’s so special about individually wrapped coils? As opposed to Bonnell coils and hourglass coils, which are interlaced across the mattress, each individually wrapped coil in a mattress stands alone, wrapped in a fabric pocket. This pocketed coil structure lends greater breathability to the mattress. Pocketed coils are also more reactive to individual body movements, changing position as the body changes position.
While we personally don’t feel that charcoal-infused foam is quite as effective as gel-infused memory foam, it’s a popular additive to memory foam that some sleepers swear by. Activated charcoal, combined with breathable open-cell foam, can add breathability and cooling to the mattress.
While graphite might make you simply think of pencils, this mineral agent is known to help wick away body heat and keep hot sleepers from feeling stifled. All Tuft & Needle mattresses, including the Original, Mint and Tuft & Needle Hybrid mattress, use graphite-infused foam to cool the body. The Bear Original mattress also includes Graphite-Gel memory foam.
Mattresses advertised to have cooling properties will often use gel-infused memory foam in the construction to aid in heat absorption and temperature regulation. Whether in gel beads or infused throughout the mattress, gel-infused foam often feels cool to the touch. It’s one of the best ways that mattress manufacturers can counteract the overheating tendency of memory foam. Mattresses like the Brooklyn Bedding Sedona and the DreamCloud Premier include gel-infused foam.
Celliant is a synthetic fiber often incorporated in premium mattress fabrics. It reacts to heat produced by the body to create increased airflow and breathability, which is important for those who produce more body heat when they sleep. The Bear Original mattress uses Celliant fiber in its construction for better cooling.
Lycra is a stretchy, elastic synthetic fabric also known as spandex. In the mattress space, a lycra cover offers breathability. It might not feel cool to the touch, but it will certainly allow for ample airflow. In contrast, a soft cotton cover will feel less breathable and stretchy.
Tencel is an environmentally friendly fabric originally made from wood. Included in many clothing and sleep products, Tencel helps absorb moisture to keep the skin cool. In a mattress, a tencel cover is a great eco-friendly cooling option that wicks away sweat.
There’s no point in buying a state-of-the-art stereo system if you’re just going to hook it up to outdated or blown speakers. We can say the same for investing in a quality mattress. You don’t want to spend time researching and then spend your hard-earned money, only to top your new mattress with bedding made from materials that will work against its cooling properties. As far as sleep accessories, here’s what you want to look for.
When choosing sheets, both dryness and comfort should be top priorities for hot sleepers. Look for sheets that are ultra-soft and made with moisture-wicking materials that carry heat away. Several good materials to keep in mind are:
Whether you are budget-conscious and aren’t ready to make the investment, you have a premium mattress and want additional cooling, or you live in an area where a cold mattress isn’t ideal all year long, mattress covers, pads and toppers are a great alternative that cuts down on costs. If you are in the market for a mattress cover or topper, keep in mind the same keywords we discussed in the previous sections.
There are many cooling pillows available today, but they aren’t all equal in quality. Generally, pillows with a shredded latex filling or those that have a gel construction are best. One other popular option is a bamboo pillow. Bamboo pillows contain natural fibers designed to keep you cool and comfortable all night long.
