Honorable Mentions: Beyond the Top Picks
While the market is flooded with products boasting cooling properties, some stand out for their innovative approaches or exceptional value, even if they didn’t quite make our ultimate "11 Best" list. These "Honorable Mentions" represent solid choices that cater to specific needs or offer unique solutions for hot sleepers. We put these through extensive testing, and while they performed admirably, the top-tier options offered a slightly more refined or comprehensive cooling experience. Nevertheless, they are certainly worth considering depending on your personal preferences and budget.
BedJet 3 for $427: A Climate Control Revolution
For those who love their current mattress but desperately seek a cooler sleep experience, the BedJet 3 offers an ingenious solution that bypasses the need for a full mattress replacement. Our WIRED reviewer, Christopher Null, was particularly impressed with this climate-control device, noting its effectiveness in allowing him to sleep cool without the significant investment of a new bed.
The BedJet 3 operates on a simple yet highly effective principle: a powerful blower unit, discreetly placed under your bed, circulates either warm or cool air directly beneath your covers. This targeted airflow creates a personalized microclimate around your body, actively wicking away heat and moisture. Unlike traditional air conditioning that cools the entire room, the BedJet focuses its efforts precisely where it’s needed, offering a more efficient and customizable cooling (or heating) experience. Its "Biorhythm Sleep Technology" allows users to program specific temperature changes throughout the night, mimicking the body’s natural sleep cycle and optimizing thermal comfort for each sleep stage. This level of customization is a game-changer, especially for couples with different temperature preferences, as it can be used on one side of the bed or with dual zone options. If your existing mattress provides adequate support and comfort but falls short on cooling, the BedJet 3 could indeed be just the ticket to transform your sleep environment. It represents a smart, cost-effective alternative to a new cooling mattress.
Sealy Cocoon Chill Memory Foam Mattress for $919: Firm Support with a Cool Touch
The Sealy Cocoon Chill Memory Foam Mattress immediately makes an impression with its noticeably cool-to-the-touch surface. This instant cooling sensation is attributed to its exclusive phase change material integrated into the cover, which actively draws heat away from your body and stores it, preventing heat buildup that often plagues traditional memory foam. This innovative material adapts to your body temperature, providing a consistent cooling effect throughout the night.
As an all-foam mattress, the Cocoon Chill leans firmly on the firmer side of the spectrum. This characteristic makes it an excellent choice for back and stomach sleepers, who typically benefit from a more supportive surface that keeps the spine properly aligned without excessive sinking. The firm feel prevents the hips from dipping too far into the mattress, which can be a common issue for these sleeping positions. However, for side sleepers who require more pressure relief and contouring around the shoulders and hips, this mattress might feel a bit too rigid. If you’re a stomach sleeper specifically seeking a firm, supportive, and effectively cooling mattress, the Cocoon Chill is a strong contender. During our testing, we observed almost no motion transfer, a crucial feature for couples. My husband and I were able to get up at different times without disturbing each other, highlighting its ability to isolate movement effectively. The combination of its firm support, excellent motion isolation, and innovative phase change cooling technology makes it a compelling option in its price range.
Casper Snow Hybrid for $2,595: Living Up to Its Icy Name
When a mattress carries the moniker "Snow," expectations for its cooling capabilities naturally run high, and the Casper Snow Hybrid largely lives up to this frosty promise. This mattress is engineered with a multi-layered approach to cooling, starting with its name. Structurally, it’s a hybrid bed, combining the pressure-relieving qualities of poly foam and memory foam with the responsive support of pocketed coils. This blend aims to offer the best of both worlds: contouring comfort without the excessive heat retention often associated with traditional memory foam, thanks to the airflow promoted by the coil layer.
Beyond its hybrid construction, the Casper Snow incorporates specific cooling technologies designed to dissipate heat. It also provides targeted support at the hips, waist, and lower back, a feature Casper is known for, aiming to alleviate pressure points and promote proper spinal alignment. This makes it particularly well-suited for back and stomach sleepers who benefit from zoned support.
During the initial setup, I noted that the mattress came out of its packaging slightly misshapen and emitted a faint, plasticky scent – common occurrences with bed-in-a-box products. However, after approximately two days, the mattress fully expanded into its intended neat rectangle shape, and the initial off-gassing odor completely dissipated, indicating good ventilation. Once settled, its cooling effect was evident, providing a comfortable temperature for a hot sleeper like myself. While the initial unboxing required a bit of patience, the long-term cooling performance and targeted support make the Casper Snow Hybrid a commendable choice for those prioritizing a cool and supportive night’s rest.
Saatva Memory Foam Hybrid for $2,049: A Firm Foundation with Cooling Ambitions
The Saatva Memory Foam Hybrid is explicitly marketed as a firm mattress, and in our testing, it certainly delivered on that promise. This bed is meticulously crafted with Saatva’s patented AirCradle memory foam, which is strategically designed with concentrated cushioning in the center. This particular feature is intended to provide enhanced support for the lower back, a common area of discomfort for many sleepers.
However, personal fit plays a significant role in mattress effectiveness. As someone who is only 5’2" tall, I found that the middle-back cushioning didn’t quite align with my intended lumbar region. This highlights the importance of considering one’s body type and height when evaluating mattresses with zoned support systems. Despite its undeniable firmness, I didn’t find this mattress to be particularly exceptional, especially concerning its cooling properties. Saatva incorporates a "triple-phase LuxeCool system" and cooling gel-infused memory foam, technologies typically designed to draw heat away from the body. Yet, during my evaluation, the cooling effect didn’t stand out as remarkably as some other contenders on this list. While it offers a firm, supportive sleep surface and excellent build quality characteristic of Saatva products, those prioritizing a truly pronounced cooling sensation might find its performance in this specific area to be average rather than revolutionary. It remains a solid option for individuals who prefer a very firm bed and prioritize robust support, but perhaps not the absolute top choice for extreme hot sleepers.
Wayfair Sleep 12-Inch Medium Cooling Gel Memory Foam Mattress for $500: Affordable Cool Comfort
For sleepers seeking an effective cooling solution without breaking the bank, the Wayfair Sleep 12-Inch Medium Cooling Gel Memory Foam Mattress presents a compelling option at an attractive price point of $500. This bed is intelligently constructed with four distinct layers of hypoallergenic gel memory foam, further enhanced with a green tea infusion. The green tea component serves a dual purpose: aiding in freshness and natural odor absorption, which can be a welcome bonus for memory foam mattresses.
The core of its cooling technology lies in the gel infusion and its breathable design. The mattress features two top layers of gel-infused memory and comfort foam, specifically engineered to promote breathability and actively dissipate heat. Complementing these internal layers is a breathable knitted cover, designed to facilitate continuous airflow circulation. This combination proved highly effective in our tests. I found this medium-plush bed struck an excellent balance, offering the conforming comfort of memory foam while maintaining a consistently cool sleeping surface. The breathable knitted cover genuinely contributed to the overall airflow, preventing heat buildup. Most importantly, throughout the testing period, I consistently slept coolly on this unexpected gem – truly a "sleeper hit" in the cooling mattress category. Its blend of affordability, comfort, and noticeable cooling capabilities makes it a strong recommendation for budget-conscious hot sleepers.
Wayfair 10.5-Inch Plush Cooling Gel Hybrid Mattress for $536 (King): Plushness Meets Cooling
The Wayfair 10.5-Inch Plush Cooling Gel Hybrid Mattress offers a luxurious, plush feel combined with cooling technology, all at a competitive price, especially for a King size. This mattress is a sophisticated blend, comprising five distinct layers of various memory foams and a supportive coil system. The uppermost layer is a memory foam pillow top, specifically engineered to cradle the body, relieve pressure points, and significantly reduce motion transfer – a benefit greatly appreciated by couples.
To combat heat, this hybrid incorporates cooling gel technology within its foam layers and features a breathable knit cover designed to enhance airflow. While its cooling effect might not be as overtly pronounced as some of the more specialized, high-end options on this list, it provides a consistent and comfortable temperature regulation alongside its plush feel. This mattress truly delivers on its promise of plushness, making it ideal for those who prefer a softer, more enveloping sleep surface. It is also compatible with an adjustable base, adding to its versatility. Wayfair backs this mattress with a reassuring 100-night trial and a 10-year warranty, providing peace of mind for buyers. For sleepers seeking a genuinely plush mattress that also integrates reliable cooling gel technology at an accessible price, this model from Wayfair is an excellent choice.
Wayfair Sleep 8-Inch Medium Cooling Gel Memory Foam for $400: Exceptional Value
In the realm of budget-friendly cooling mattresses, the Wayfair Sleep 8-Inch Medium Cooling Gel Memory Foam stands out as a "super-cheap" option that significantly over-delivers on expectations. Priced at just $400, this medium-firm mattress packs an impressive eight inches of memory foam, thoughtfully layered for both comfort and thermal regulation. The top layer is a unique blend of cooling gel, charcoal, and green tea-infused memory foams. This innovative combination not only aids in cooling but also leverages charcoal’s natural properties for freshness and odor absorption, and green tea’s benefits for maintaining a clean sleep environment. This is followed by a soft comfort foam layer, resting on a durable high-density foam base for robust support.
The mattress is further enhanced by a breathable, woven jacquard design on its top layer, which actively helps to keep the sleeper cool by promoting air circulation and reducing heat buildup. This design also contributes to reducing motion transfer, ensuring undisturbed sleep even with a partner. The layers of ultra-cooling gel and green tea-infused memory foams work in concert to provide a noticeable cooling effect and effectively keep any odors at bay. While there are certainly better cooling options available on our broader list, the Wayfair Sleep 8-Inch offers remarkable performance for its incredibly low price point. It’s an ideal choice for students, guest rooms, or anyone on a very tight budget who still demands effective cooling and comfortable support.
Wayfair Sleep 14-Inch Plush Cooling Gel Hybrid Mattress for $326 (Full): Deep Plushness with Airflow
The Wayfair Sleep 14-Inch Plush Cooling Gel Hybrid Mattress, available for a full-size bed at just $326, is a testament to Wayfair’s commitment to offering diverse and affordable sleep solutions. This mattress is designed for those who crave a deeply plush sleep surface, combining generous layers of foam with a classic coil system. It features a top plush layer of gel memory foam, engineered not only to relieve pressure points but also to actively assist with airflow. This is further complemented by a quilted Euro-top knit cover and strategically designed sides, which collectively promote continuous airflow around the entire mattress, effectively keeping the sleeper cool.
Beneath the comfort layers, the bed incorporates classic pocket coils, providing essential structure, responsive support, and durability. These coils are surrounded by additional layers of memory foams, which contribute to the mattress’s low-motion transfer capabilities, minimizing disturbances from a partner’s movements. This mattress boasts solid edge support, ensuring that the entire surface is usable and comfortable, even when sitting on the side. It’s also compatible with an adjustable bed base, offering enhanced functionality. Wayfair provides a 100-night trial and a 10-year warranty, reflecting confidence in its product. While I personally appreciate a plush mattress, it’s worth noting that the initial super-soft memory foam layer on top of the coil system might be too plush for individuals with a larger body type, who might prefer more underlying support. Nevertheless, for those who love a soft, enveloping feel coupled with effective cooling and robust features, this mattress offers exceptional value.
Wayfair Sleep 13.5-Inch Medium Cooling Gel Memory Foam Mattress for $550: A Plush Behemoth for Moisture Wicking
Despite being listed as a "medium" mattress, the Wayfair Sleep 13.5-Inch Cooling Gel Memory Foam Mattress, priced at $550, is undeniably a super-plush experience. This substantial bed is constructed with a thoughtful layering system: a generous 2-inch top layer of gel-infused memory foam, followed by 4.5 inches of comfort foam, and finally, a robust 7-inch high-density base support foam. This combination is engineered to provide deep contouring and pressure relief.
Like other cooling Wayfair mattresses, the top surface features a breathable jacquard pattern, which is also green tea-infused. This infusion serves a dual purpose, enhancing freshness and contributing to the overall cooling effect by helping to wick away moisture. The plush top layers of memory foam are specifically designed to mold intimately to your body’s unique contours, effectively alleviating pains and soothing achy joints. This "bed-in-a-box" also boasts low-motion transfer, making it an excellent choice for couples. With a 100-night trial and a limited 10-year warranty, Wayfair stands by its product. If your ideal sleep scenario involves a deeply plush, enveloping bed that actively helps to wick moisture and keep you cool, then this impressive, thick mattress is a strong recommendation. Its combination of luxurious comfort, targeted pressure relief, and active cooling features makes it a standout for plush-loving hot sleepers.
Compare the Best Cooling Mattresses: Our Rigorous Testing Methodology
At WIRED, our commitment to providing honest, unbiased, and thoroughly researched reviews is paramount, especially when it comes to something as crucial as sleep. Our testing process for cooling mattresses is comprehensive and designed to simulate real-world usage over extended periods.
How Does WIRED Test Cooling Mattresses?
Each mattress undergoes a minimum of a week of testing, but in many cases, we extend this period to half a month or even longer. This allows our reviewers to truly "get a feel" for the product, observing its performance and durability over time. We test these mattresses across different seasons and with various types of sheets and bedding to understand how they perform under diverse environmental conditions and with different material interactions.
Beyond simply sleeping on them, our testing involves specific physical assessments. We sit on the edges to evaluate edge support, which is crucial for maximizing usable sleep surface and for ease of getting in and out of bed. We also perform tests involving jumping and other methods to accurately gauge the bounce and motion transfer characteristics of each mattress. This is particularly important for couples, as low motion transfer ensures one partner’s movements don’t disturb the other.
Perhaps most critically for this guide, our reviewers—many of whom identify as perpetually warm (and often sweaty) sleepers—serve as living thermometers. We gauge abstract yet vital factors such as overall comfort throughout the night, how well we perceive air to flow through the mattress’s layers, and, most importantly, how much heat is trapped (or effectively dissipated) by the mattress. This subjective experience, combined with objective observations, forms the core of our assessment.
What Should You Look for in a Cooling Mattress?
When embarking on the search for the perfect cooling mattress, several key factors should guide your decision-making process:
- Materials and Construction: Look for mattresses made with breathable materials. This often includes open-cell memory foam, which has a less dense structure allowing for better airflow, or gel-infused memory foam, where cooling gel particles are integrated to absorb and dissipate heat. Latex mattresses are naturally more breathable and responsive than traditional memory foam. Hybrid mattresses, which combine foam layers with innerspring coils, are excellent for cooling due as the coils create air channels that promote significant airflow.
- Specific Cooling Technologies: Beyond basic materials, some mattresses incorporate advanced cooling features. Phase Change Materials (PCMs) are often woven into mattress covers or top layers; these materials react to your body temperature, absorbing heat when you get too warm and releasing it as you cool down, maintaining an ideal surface temperature. Copper infusions can also be found, touted for their thermal conductivity and antimicrobial properties.
- Firmness Level: While not directly a cooling feature, firmness can indirectly affect how cool you sleep. A mattress that is too soft might allow you to sink too deeply, encapsulating you and potentially trapping heat. A firmer mattress, on the other hand, can keep you more "on top" of the bed, allowing for better air circulation around your body.
- Breathable Cover: The mattress cover plays a significant role. Look for covers made from natural fibers like cotton, Tencel, or specialized performance fabrics designed to wick away moisture and enhance breathability.
- Edge Support: Good edge support means the entire surface of the mattress is usable and comfortable, preventing you from rolling off and potentially giving you more room to spread out, which can aid in cooling.
- Motion Isolation: While not directly related to cooling, good motion isolation is important for undisturbed sleep, especially for couples.
How Did WIRED Select Models to Be Reviewed?
Our selection process is extensive and iterative. We have tested well over 100 mattresses across all of our various buying guides, including our "Best Organic Mattresses," "Best Mattresses for Back Pain," and "Best Mattresses You Can Buy Online," in addition to individual product reviews. We maintain an open dialogue among our team of reviewers, discussing which mattress brands generally meet our high standards and which consistently fall short.
To ensure a comprehensive review, some mattresses are provided to us as review samples by manufacturers. It’s crucial to understand that there’s a strict understanding: we do not guarantee coverage or a specific type of coverage. We are never paid for glowing reviews on products we believe are mediocre or "just mid." Our integrity is paramount. In cases where we cannot obtain a review sample, we purchase and expense models ourselves, ensuring that our reviews remain completely independent and free from any potential influence. We strive to test a wide range of mattress types, firmness levels, and brands to gain a holistic understanding of the market. This allows us to provide you with our honest, unbiased opinion on which mattresses are truly worth your hard-earned money and the one-third of your life you’ll spend sleeping on them.
What Does WIRED Do With Mattresses After Testing?
Our responsibility doesn’t end after the initial testing period. Top-performing mattresses that earn our recommendation are often kept for longer-term durability testing. These are distributed among our own homes, as well as the homes of other trusted staffers, friends, and family members. This extended usage allows us to assess how the mattresses hold up over time, identifying any potential issues with sagging, material degradation, or sustained cooling performance. Other models that don’t make our top picks or are no longer needed for testing are thoughtfully donated locally to various charities and organizations, ensuring they find a good second home and minimize waste.
Choosing the right cooling mattress is an investment in your health and well-being. With the advancements in materials and technology available in 2025, hot sleepers no longer need to suffer through restless, sweaty nights. Whether you opt for a dedicated cooling mattress or a climate control device, finding the perfect solution will lead to more comfortable, refreshing sleep.
