Best Mattress for Hot Sleepers of 2018 & Buying Guide
You know the feeling: you wake up in the middle of the night or early morning, groggy, thirsty, and sweating so much, you briefly wonder if the roof has sprung a leak. For some people, this only happens when the thermostat malfunctions, or as the seasons change—but for many, overheating is an all too common occurrence that prevents them from getting their best night’s sleep.
Sure, you can kick off the sheets, ditch the comforter, crank up the air conditioner, or even sleep au naturel. These tricks help, but might not be solving the real issue at hand: your mattress is to blame.
Our buyer’s guide will answer common questions about overheating at night, as well as showcase some mattresses best suited for folks who are sick and tired of waking up in a heat flash.

What causes nighttime overheating?
To be clear, we can’t (and don’t want to!) diagnose anyone with this article; we can only address those individuals whose excessive heat or sweating is caused by their mattress. Some people have medical conditions at play, or hormonal variances such as pregnancy or menopause. If your nighttime sweating and heat flashes are new or severe, please consult your doctor.
That said, if you’re sure your overheating isn’t due to a condition (or if you know it is, and wish to replace your mattress due to a doctor’s recommendation), read on.
When a mattress is built with too-dense materials or constructed very thinly, less air can circulate underneath. Body heat builds up in the materials and chambers, which can make it difficult for your body to regulate its own temperature effectively.
Additionally, the fabric on the top of your mattress and sheets might be very tightly-woven, which traps even more heat. Seek materials that diffuse heat and stay cool to the touch. Many mattresses come with gel-infused top layers, which can help this problem. It’s also a good idea to choose sheets and pajamas designed to wick away moisture; the dryer your skin is, the cooler it will feel (and the less likely it is you’ll wake up feeling like you conked out in a swamp).
What if my partner runs cold/hot, and I’m the opposite?
This is a tricky compromise to find, on par with different sleeping positions between partners. The quickest solution: separate beds, or even bedrooms. This isn’t always desirable or possible, however. When choosing a mattress to suit both your needs, look for options between cool and warm, or adjustable models with temperature control options. The easily chilled partner can also dress more warmly or use additional blankets, since, generally speaking, it’s easier to warm up in bed than it is to cool down.
Should I change my sleeping position?
Possibly. Those who sleep mostly or exclusively on their stomachs do tend to overheat more often than side and back sleepers, since their heads, faces, and chests—the areas most sensitive to heat—are pressed into the mattress and pillows.
If a new mattress designed for maximum ventilation doesn’t help, consider changing your position to the side or back. Body pillows can help keep you in place during the night. Failing that, a modified position—such as halfway on your stomach, half on your side, and propped up with pillows—can optimize airflow to your face and chest throughout the evening.
What’s best for cooling off: memory foam, spring, or hybrid mattresses?
All three types have their advantages, although it takes some careful research to determine which mattress will keep you cool. The real challenge is finding one that diffuses heat and provides the support and comfort your particular sleeping position requires.
Overall, memory foam models tend to retain more heat than spring ones, but are typically far more comfortable (and quieter). A hybrid offers the best of both, but doesn’t always provide the same comfort as all-foam designs.
With hybrids or all-foam options, look for thinner or gel-infused foam layers on top, and large spring or chamber cores within the base of the bed. These will allow more air to circulate, instead of pushing the heat back up against your body.
Do waterbeds stay cooler?
Yes—much cooler. In fact, unless you regulate the temperature in your home carefully during season changes, you might find your bed is too cold come winter!
For those wary of motion-sickness (or just motion annoyance), waterbeds come in three varieties: free flow, which is essentially big, square water blobs; semi-waveless, which feature inserts and chambers to partially control the water’s movements; and completely waveless, which limits the water’s motion almost entirely—think of like a giant sponge. Keep in mind, though, that the more inserts the bed has to control its motion, the warmer it will get. Still, even waveless waterbeds stay cooler than traditional mattresses.
We won’t be reviewing waterbeds in this article, since they’re still a non-traditional choice for most people. If you’re considering one as a solution to nightly overheating, keep in mind that these beds require additional accessories and upkeep.
Best Mattress for Hot Sleepers Review
1. Resort Sleep 10″ Memory Foam Mattress Review
Although this isn’t a hybrid, the Resort Sleep 10″ Memory Foam model can still provide the elusive blend of softness and ventilation hot sleepers so desperately desire. Its top layer is designed to contour to the body, yet not so dense that it traps heat.
If you’re a side or back sleeper who runs mildly hot, the Resort Sleep 10″ Memory Foam mattress is a way to have your cake and eat it too: you get the ventilation you need, and the softness you want. If you run moderately hot, it still might suffice—but extremely hot sleepers should explore other options.
2. Classic Brands Cool Gel Ultimate 14″ Mattress Review
A low-range price point makes this model affordable for almost every budget, and boasts the very same cooling gel you’d find in expensive options. The gel and memory foam are combined, which provides firm comfort with effective heat dispersal.
The Classic Brands Cool Gel Ultimate model is a sound choice for keeping cool without sacrificing comfort. The gel-and-foam combination layer’s aeration can prevent too much heat from building up underneath you, while providing a fast-acting contour for cushioning sleepers in every position—however, if you’re an exclusive side sleeper, it might not prove soft enough.
3. Brentwood Home Cypress Mattress
The Brentwood Home Cypress has a decent price tag for all its features. With 3.5″ of gel-foam and a cover specifically designed for sweaty sleepers, it optimizes pressure relief for your joints, and temperature regulation for the rest of you.
If you’re a couple constantly fighting over the thermostat, the Brentwood Home Cypress might prove to be a viable compromise. Its wool-lined cover is a unique feature that adapts to both extremes of the temperature spectrum, ensures a dry night’s sleep, and prevents odor retention. Cooling gel and a ventilated core should alleviate excess heat, and give side and back sleepers the contoured support their neck, spine, and hips require.
4. Tuft and Needle Adaptive Foam Mattress Review
While its price is at the higher end, the Tuft and Needle Adaptive Foam mattress boast enough cooling technology to justify it. What’s more, the company says 95% of its clientele keep their mattress—although they do offer a 100-night trial and return policy for a full refund, just in case you change your mind.
With its 100-night trial and full return policy, the Tuft and Needle Adaptive Foam mattress is worth a shot. The unique technology offers a solution to the dreaded “sag and sink” from typical memory foam mattresses, and strikes a balance between firm and soft that many individuals (and couples) will enjoy. It should perform well for moderately hot sleepers.
The search for a mattress with sufficient cooling, wicking, and ventilation technology for a fair price can be exhausting (especially when you already aren’t sleeping well), but you can narrow your options down by looking at models with certain components:
The gel isn’t a necessity, but does work very well at absorbing and diffusing heat. If you’re keen on memory foam, a gel-foam mixture is a must.
Cores should feature chambers or channels, to maximize airflow as much as possible. Most sellers will showcase this element, if their mattress offers it; look for diagrams that illustrate how each layer is constructed.
Taller mattresses will be less dense, and therefore trap less heat as the night goes on; by contrast, thinner options will probably trap more. Aim for at least 10″ in total height.
In addition to the models we’ve featured here, hot sleepers can explore hybrid foam-spring mattresses, electric temperature control tops, and moisture-wicking sheets and covers. Temperature regulation doesn’t come from a one-size-fits-all solution, since people overheat for different reasons, and at different levels. However, we hope we’ve provided some insight and possible solutions to those whose current mattress is to blame. You might run hot, but your mattress definitely shouldn’t.
