8 Best Cooling Mattresses in 2024 | Tested by Experts

The Nectar Premier Copper Hybrid is our pick for the best mattress for hot sleepers standing out and earning our “Best Overall” rank for its blend of comfort, support, and advanced cooling technology. Its hybrid design combines contouring memory foam with sturdy, individually wrapped coils, offering pressure relief and robust support. The mattress’s cooling feature is especially notable, with copper-infused layers and gel memory foam that work together to regulate temperature.

The Nectar Premier Copper Hybrid provides a unique balance between the responsive bounce of coils and the soft, conforming, cradle-like feel of memory foam. Its copper-infused top layer not only enhances cooling but also adds antibacterial properties. The bed’s design is particularly beneficial for back pain sufferers and those who prefer sleeping on their backs or sides.

Our tester, Stuart, a 170-pound side sleeper, said, “The top is very soft, which was comfortable. And the responsiveness of the coils saves me from sinking too deep into the mattress.” The coils give it excellent edge support, something important for couples, which can be an issue for all-foam models. The foam layers on top give it exceptional motion isolation, another feature that couples value. The use of high-quality materials and a lifetime warranty mean a longer lifespan than your average mattress. Any warranty claims made after the 10-year mark will result in Nectar sending you a brand-new mattress. Finally, Nectar has one of the longest trial periods in the industry, allowing you an entire year to decide if you are happy with your purchase (the trial periods in this review range from 90 days to one year).

Customer reviews

Nectar Sleep has an A+ rating and 2.85 out of 5 stars on BBB with 440 customer reviews. While many customers are thrilled with their Nectar mattresses, complaints are generally about delivery complications. It seems the company was recently experiencing order fulfillment problems. Nectar is always quick to respond to complaints and attempt to correct the problem, thus the A+ rating despite many complaints.

Nectar has 3.3 out of 5 stars on Trustpilot with more than 23,000 reviews. Overall, customers are happy with their mattresses and experience, most reported on-time deliveries and appreciation for the ability to select their delivery date and time. Some reviews mentioned issues with the mattress warranty (sagging and indentation) that were satisfactorily handled by the company.

With medium firmness and plush comfort, the Helix Midnight Luxe is particularly suited for side sleepers. The mattress provides the perfect balance of support and pressure relief, with foam layers that cushion the shoulders, hips, and lower back—areas often subject to pressure points for side sleepers. The top two foam layers conform closely to the body, spreading weight evenly and ensuring spinal alignment. As an added bonus, the zoned coils offer reinforced support under the midsection, enhancing comfort and preventing the pain and numbness that side sleepers frequently experience.

Our survey of 600 respondents reported 48.5% of new mattress customers are primarily side sleepers (compared to 17% back and 14% stomach). The Helix Midnight Luxe stands out for its temperature regulation capabilities and medium-firm plush comfort for side sleepers. The Tencel cover is highly breathable and moisture-wicking, keeping the sleeper dry and comfortable. For added cooling, you can select a GlacioTex cooling cover for $249. The mattress’s gel-infused memory foam and pocketed coil layer further enhance airflow and heat dissipation. The reinforced edges of the mattress provide exceptional edge support compared to other hybrids, allowing sleepers to use the entire mattress surface without feeling like they’ll roll off.

Emma, our 140-pound tester, said, “I really appreciate the versatility of the Midnight Luxe and I particularly love how it feels when I’m sleeping on my side. The pillow top adds a little bit more cushioning than the standard Midnight does, and the zoned support also keeps my spine aligned overall.” This mattress also performs well in terms of motion isolation and ease of movement, making it an excellent option for couples. Emma concluded testing by saying, “If you’ve got the extra cash to spend, and you want enhanced support, cushioning up top, and cooling, then the Luxe is worth it.”

Customer reviews

Helix Sleep has an A+ rating but only 1.48 out of 5 stars on BBB, but this is only from 29 customer reviews. It only has six reviews on Trustpilot, where it has 2.5 out of 5 stars. It’s difficult to get a full appreciation for customer satisfaction from so few reviews. Complaints are around poor customer service, shipping delays, and warranty disputes.

The Helix Midnight Luxe has a positive 73 out of 100 rating on Consumer Reports. While most customers are pleased with their purchase, some complain the mattress is not as cooling as they would like.

The Emma Hybrid Comfort is a top choice for back pain sufferers looking for firm support and spinal alignment. Its combination of cooling features, firmness, and supportive design makes it a versatile option for a wide range of sleepers, particularly those dealing with back discomfort.

Back pain is a common complaint among mattress consumers. Our January 2024 survey found 59% of respondents reported purchasing a new mattress specifically to treat lower back pain.

The Emma Hybrid Comfort mattress combines foams and sturdy coils, providing a bouncy and supportive feel. The mattress is designed to accommodate all body types and can support up to 1,000 pounds. It provides a medium-firm to firm feel, which is helpful for maintaining spinal alignment, especially for back sleepers. A recent review of 39 studies on back pain and sleep ^[2] Gianphilipo C. What Type of Mattress Should Be Chosen to Avoid Back Pain and Improve Sleep Quality? Review of the Literature. Journal of Orthopeadics and Traumatology. December 2021. Found on the internet at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8655046/ found a medium-firm mattress is best for those with non-specific lower back pain. The zoned support system offers enhanced pushback in the lumbar region, which is crucial for preventing and easing back pain. It has minimal sinkage, making it a good option for combination sleepers and those who have difficulty getting out of bed.

Despite its firmness, the mattress surprisingly offers good pressure relief; but it may not feel as plush as some all-foam mattresses, which could be a factor for side sleepers seeking more cushioning. The mattress’s cooling features, such as the moisture and heat-wicking UltraDry top cover and the breathable Airgocell poly foam, make it a good option for hot sleepers.

Our tester, Julia, said, “The Emma Hybrid Comfort is squarely at a seven out of 10 on the firmness scale. You get a good responsive feel from the coils, but not a whole lot of sink on the surface level. This is really appealing for those who need solid back support because of the good weight distribution and spine alignment the bed offers. Spine alignment is where this mattress excels because the firm surface is good at spreading out your body weight evenly and keeping the spine lifted.”

Customer reviews

Emma Sleep only has two reviews on BBB and 3 out of 5 stars on Trustpilot from more than 13,000 reviews. While 50% of customers give them 5 stars, most complaints are regarding shipping delays and difficult-to-reach customer service.

The Bear Elite Hybrid offers an excellent combination of advanced cooling technologies and multiple firmness levels, catering to a wide range of sleep preferences. With options for soft, medium, and firm levels, the Bear Elite Hybrid can accommodate different sleeping styles and preferences, making it an ideal choice for a diverse range of sleepers. It is our pick for “Most Versatile Cooling Mattress” because it caters to people with back pain, couples, athletes, and everyone else looking for a comfortable, high-quality bed that can last for years.

The Bear Elite Hybrid helps keep sleepers cool with its mix of a Celliant (a synthetic fiber that wicks moisture and helps regulate body temperature) and polyester blend cover with phase change material (materials that regulate temperature by absorbing excess heat and humidity), copper-infused memory foam, and a zoned polyfoam layer that provide superior cooling and comfort. The individually wrapped coils add to the breathability, enhancing temperature regulation across the mattress. Our tester, Stuart, said, “Another great thing about this mattress was the cooling top. The cooling was immediately noticeable as I laid down on the bed, and I’m pretty sure it would do a good job of keeping anyone cool throughout the night.”

The Bear Elite Hybrid is designed to offer a balance of cushioning and support. Its foam layers provide pressure relief and comfort, while the zoned pocketed coils ensure proper spinal alignment and support. This mattress performs well in terms of ease of movement, making it a good choice for combination sleepers. It also offers varying levels of edge support, with the firmer models providing more robust edge support than the softer version. The mattress is particularly well-suited for back and side sleepers, offering adequate support and comfort across different body weights and sleep positions. It also works well for couples who want a reduction in motion transfer while still enjoying luxurious comfort and zoned support. This versatile range of features allows the Bear Elite Hybrid to cater to a diverse set of sleep needs and preferences.

Bear Mattress only has four reviews on the BBB and six on Trustpilot. While ratings are low for both, there are not enough reviews to get a clear vision of overall customer satisfaction. More than 3,700 customer reviews on the Bear website give the company a 4.6-star average rating.

The Saatva Latex Hybrid is an excellent choice for those seeking a hybrid mattress with superior cooling capabilities. Its combination of natural latex, organic materials, and a robust coil system not only ensures a cool sleeping experience but also provides strong support and durability. It earns the title “Best Cooling Hybrid” due to its quality construction, cooling capabilities, generous trial period and warranty, and free white glove delivery (installation of new cold mattress and removal of old).

The combination of natural latex and individually pocketed coils that excel in temperature regulation makes the Saatva Latex Hybrid an outstanding choice for a hybrid cooling mattress. The latex layer is not only durable and responsive but also naturally cooling. Our tester, Julia, pointed out, “The latex looks like it’s been hole-punched––this is a good thing. These extra air pockets create a natural passageway for body heat to flow away from you, and coils beneath the latex create space in the mattress for it to keep going. Latex isn’t going to hold onto heat the way foam does, and it’s a nice natural alternative.” This mattress is particularly suitable for hot sleepers, those suffering from back pain, and anyone who prefers firmer support.

The Saatva Latex Hybrid features a layer of organic wool that serves as a fire barrier and adds breathability near the surface. The comfort layer is made of ventilated Talalay latex, known for its even conforming and responsiveness. The support core has zoned pocketed coils that reinforce the mattress’s edges and provide excellent overall support.

The mattress’s cover is made from organic cotton, adding to its luxurious feel and breathability. It’s a great fit for those who need firm support, such as back and stomach sleepers, but might not offer enough contouring for those who prefer a softer, more enveloping feel.

Customer reviews

Saatva has an impressive 4.79 out of 5-star rating on BBB and an A+ rating with 1,730 customer reviews. Similarly, they have a 4.6 out of 5-star rating on Trustpilot with 1,158 customer reviews. Customers commonly rave about exceptional customer service and even report sales being retroactively honored. Customers are also overwhelmingly happy with their Saatva mattresses and the quality of sleep they now enjoy.

The Cocoon Chill Hybrid mattress stands out as a top choice for an affordable cooling mattress. Its combination of cooling technologies, a supportive coil system, and memory foam comfort makes it a compelling option for a wide range of sleepers, especially those looking for a cooler sleep experience without breaking the bank.

The Cocoon Chill Hybrid by Sealy is a standout choice for an affordable cooling mattress, blending the contouring comfort of memory foam with the responsive support of innerspring coils. Its cool-to-the-touch stretch-knit cover works in tandem with a dual-layer comfort system comprising a memory foam top layer and a base of pocketed spring coils. This design not only hugs the body for comfort but also enhances breathability and support, making it excellent for average-weight sleepers across various positions. The reinforced edges offer robust edge support, beneficial for those who frequently sit or sleep on the bed’s perimeter.

Note that it may not be the best option for significantly heavier sleepers due to potential sinkage issues. This mattress is especially appealing to price-conscious hot sleepers or those in warmer climates, delivering a balanced feel ideal for a cool and comfortable sleep experience.

Tempur Sealy, the company that owns Cocoon, has a 1.7 out of 5-star rating on BBB with 179 customer reviews. The company responds to complaints quickly to maintain an A+ rating.

The Avocado Green Standard mattress stands out in the organic mattress category for its combination of eco-friendly materials, cooling properties, and overall comfort. Its construction caters to a wide range of sleep preferences and needs, making it a top choice for those seeking an organic cooling mattress.

The Avocado Green mattress is crafted with organic cotton, natural latex, and wool. It provides breathability and a cooler sleeping experience, further enhanced by the inclusion of an 8-inch pocketed coil system for increased airflow and zoned support. The mattress layers offer cushioning through organic wool and Dunlop latex, along with resilience. Its firm yet responsive nature suits combination sleepers, allowing ease of movement. Additionally, the use of natural materials significantly reduces off-gassing, aligning with the preferences of environmentally conscious consumers and promoting a healthier sleep environment free from synthetic chemicals and toxins.

Our tester, Stuart, said, “I’m a combination sleeper. I can spend some time on my stomach, back, or side, and I think this mattress has features that benefit all three of those positions. So it should be a nice bed for all types of sleepers.”

Customer reviews

Avocado Green Mattress has 2.12 out of 5 stars and an A+ rating on BBB with 51 customer reviews. Similarly, it has 1.8 out of 5 stars on Trustpilot with 48 reviews. Some complaints are about sinkage in mattresses, difficulties getting the warranty honored, and strong odors (off-gassing) after unboxing.

The Tempur-Pedic LuxeBreeze is a top-of-the-line luxury cooling mattress providing exceptional temperature regulation and comfort. Its premium materials and construction, along with its advanced cooling features, make it an ideal choice for those seeking a luxurious sleep experience with optimal cooling benefits.

The Tempur-Pedic Luxe Breeze is a premier choice in luxury cooling mattresses, integrating advanced cooling technology with high-quality construction. Uniquely engineered to reduce heat by up to 10 degrees, according to the company, it caters exceptionally well to hot sleepers. This mattress features adaptive TEMPUR memory foam that initially feels firmer but gradually softens as it absorbs heat, ensuring a comfortable sleep experience tailored to various positions.

Its innovative design includes a phase change material (material that helps regulate temperature) cover that wicks away heat and moisture. Our tester, Julia, said, “Very cool to touch, and can feel heat dissipating seconds after laying here. You will most definitely feel this through sheets. I didn’t feel the heat accumulate at all as I laid down.”

Available in three firmness levels, the soft all-foam model is ideal for lighter people and side sleepers, the medium hybrid model is great for most average-size combination sleepers, and the firm all-foam model provides optimal support for heavier, back, and stomach sleepers. Julia concluded, “It is very expensive and may be out of some people’s price range. But if you’re willing to make the investment, it may be worth your while.”
