Overheating is one of the most common deterrents to quality rest. When your mattress isn’t regulating your temperature as well as you’d like, a mattress topper is a viable and cost-effective alternative to replacing your bed all together. Our team tested more than a dozen toppers to determine the ones that stood out for keeping us cool versus the ones that fell short. Our top choice is the Brooklyn Bedding CopperFlex 301 Topper, the middle-tier model in the brand’s latest collection of toppers; it features a thick, 3-inch profile and upgraded cooling tech like a phase-change cover.

Don’t underestimate the power of a good mattress topper: Brands are getting more advanced with their designs, and the right choice can elevate your old mattress to a like-new model that’s better at regulating temperature. Whether it’s a pillowy-soft topper, one that’s firm or an option somewhere in between, the mattress toppers below cater to hot sleepers looking to enhance their sleep setup without overspending. You may also want to consider the best cooling pillows for even more comfort.

The CopperFlex 301 is a part of a new line of mattress toppers from Brooklyn Bedding that features copper-infused foam to help draw away body heat and a GlacioTex cooling cover, which is the same technology used in the Brooklyn Bedding Aurora Luxe, our top pick for the best cooling mattress. Senior mattress and sleep editor Bridget Chapman and I both noticed the GlacioTex cover while trying out the topper—and can confirm it does feel cool to the touch. Which wasn’t a surprise, since we already recommend the technology to those prone to night sweats.
You can tell the topper is made with memory foam, but unlike traditional memory foam, it’s not as slow-responding. It’s also infused with copper gel, a material that helps evenly disperse body heat for more comfortable sleep. Plus it’s fitted with 3-inch-thick corner straps that wrap around your mattress to keep it in place. All foams used in this topper are CertiPUR-US-certified, meaning they’re free of mercury, lead and other harmful chemicals and are low on VOC emissions. And for an even more plush and luxurious setup, consider the 4-inch CopperFlex option.
Unlike most toppers our team has tested, the Dormeo Mattress Topper utilizes a special foam design that mimics supportive springs called Octasprings. The technology is designed to diffuse body heat, increase airflow and provide balanced comfort that doesn’t compromise on pressure relief or sturdiness. “The individual foam springs deliver a comfy profile that’s plush yet supportive,” says home and sleep writer Monica Petrucci, who felt comfortable and cool while testing in every sleeping position—back, side and stomach. “The breathable design was evident. I never noticed heat buildup.”
Ergonomically designed for better spinal lift and joint relief, the topper is sectioned in three zones. “The firm zone in the middle keeps my hips lifted and in alignment without any noticeable pressure points or pain buildup,” she says, adding that lying on her back and side is just as comfortable thanks to ample cushioning. Use its adjustable straps to keep your mattress secure, regardless of its size, and enjoy easy cleaning with a machine-washable cover. Its one downside, Petrucci notes, is its motion-isolating capabilities, as she was more sensitive to her husband’s movements through the night than usual.

You’d like to drastically soften or firm up your bed
Breathability is latex foam’s strong suit, a stark difference from memory foam, which can retain heat if it’s not constructed with temperature-regulating properties. The Saatva Latex Mattress Topper is made with a 1.5-inch latex foam layer, which naturally prevents heat retention and promotes airflow with perforations. Surrounding the latex foam is a soft cotton cover that keeps you dryer through the night. “I haven’t felt overly warm when sleeping, so it seems to be doing its job nicely,” says assistant deals editor Jordan Thomas. Given the typically higher cost of natural latex foam, we think the price is hard to beat—which is why we named it the best value.
Its thinner profile gives a mattress a nuanced feel that’s not immediately obvious, according to our tester, but helpful in enhancing structure and general appeal. “It doesn’t feel cradling or sinking like a memory foam, but it definitely adds support, height and an extra layer of comfort,” says Thomas. She says it also helped curb back pain after sleeping on her side, and she “feels more on top of the mattress, versus sinking into it.” Although latex foam tends to make a mattress bouncier, note that our tester found her mattress more difficult to move around on with the topper.
Memory foam is a dense material that reacts to body temperature and softens under your curves. It’s great at absorbing movement from a partner, but it’s also known to trap heat. Tempur-Pedic, the pioneer in memory foam comfort, has addressed hot-sleeping concerns and has one of the best cooling toppers we’ve tested. “The most noticeable trait of this topper is the cooling cover,” says former editor Christine Colby, who says she could feel the low temperature through her clothing. “I’m pleased by how cool it feels to lie on, as my current mattress is leaving us a little overheated and sweaty.”
Made with 3 inches of the brand’s slow-moving foam, “I can really feel that sinking-in sensation when I lie on it. My mattress on its own is quite firm, so this does cut down on some of the firmness by adding a squishy layer on top,” she adds. With that said, it isn’t completely lacking in structure, and Colby says it isn’t soft enough to be problematic or lose support. However, she did note its irregular sizing, as the topper is an inch short on each side of her queen-size mattress. “It’s not too noticeable when sleeping on it, but it can be felt when sitting on the edge,” says Colby.

You already have a tall mattress
The Helix Premium Mattress Topper earned a spot in this roundup (and in our best memory foam mattress toppers list) because it relieves hot sleepers, accommodates a variety of sleep postures and excels at motion isolation to prevent disturbances from your partner’s movements. Our team has tested a myriad of hybrid mattresses, but we’ve seldomly come across a mattress topper that incorporates a layer of steel coils, an addition that helps make a topper feel more structured and supportive. Not only do the coils enhance sturdiness, they also promote airflow for a more breathable feel. At the same time, its memory foam layer is designed to contour around the body’s curves and help absorb motion.
This topper features a GlacioTex cooling cover, which feels cool to the touch, to provide further relief to hot sleepers. “The cooling technology is great for my husband since he sleeps really warm,” says associate director of operations Kayla Sigaroudi, adding “the extra comfort it adds is amazing. It’s like lying on a cloud but still has all the support I need.” Choose between a luxury plush or luxury firm profile; the former is ideal for side and back sleepers, while the latter option suits combination, back and stomach sleepers. The topper also stays secured to your mattress with its corner straps and a base layer that helps enhance grip.
How We Tested The Best Cooling Mattress Toppers
Our experienced editors selected the best cooling mattress toppers highlighted in our roundup based on a series of benchmarks.
Our team tested over a dozen mattress toppers that were either analyzed in a panel setting with multiple testers or in-home over the course of a month.
For this list, the most important factor to consider was each topper’s cooling technology and how well each worked for hot sleepers. While testing, we also took construction, firmness, height and materials used into account.
We focused on products that have been highly rated by customers for both cooling and comfort. Each of these products has an average of at least 4 out of 5 stars based on consumer reviews.
What To Consider When Buying A Cooling Mattress Topper
Here are a few factors to consider when shopping for a cooling mattress topper.
Cooling Features
Keep an eye out for specific cooling features when you’re looking for an effective cooling topper. The best kind of cooling topper combines two types of cooling tech, like gel-infused foam and a cooling cover. Copper gel, graphite gel, phase-change covers and latex foam all make for good cooling mattress topper materials.
Firmness
Mattress toppers come in different firmness levels and you should consider your sleeping position to help you decide whether soft or firm is best for you. “A mattress topper should help with additional conformity for firmer mattresses,” says Dr. Carla Weiss, a clinician scientist and Aeroflow Sleep’s sleep science advisor. Firm toppers, on the other hand, can add structure and support to soft mattresses. Side sleepers typically prefer a softer profile, while back and stomach sleepers tend to be more comfortable with a firmer feel.
Materials
Memory foam:Memory foam is a common mattress topper material that’s known for its pressure-relieving properties. Weiss recommends a memory foam mattress topper when you want to add more plush comfort to your mattress. However, if you’re seeking an option that will keep you particularly cool, look out for temperature-regulating materials, like gel or a cooling cover, that make it more breathable.
Latex: Latex foam can be natural or synthetic, but the most popular kind is natural or organic latex foam derived from the sap of a rubber tree. It’s whipped, baked and turned into a supportive, breathable, foam-like material. It’s also antimicrobial, naturally more breathable than memory foam and tends to be more durable.
Cotton: Cotton is commonly used as a cover for mattress toppers because it’s breathable, moisture-wicking and soft to the touch.
Wool: Some natural mattress toppers contain wool. Although it has a reputation for being a warm material, wool is actually very breathable and moisture-wicking—making it a good choice to use in cooling mattress toppers.
Height
The mattress toppers listed in our roundup are all between 2 and 4 inches thick, but toppers can be as tall as 5 inches. Anything lower than 2 inches is considered a mattress pad, which adds a small layer of cushioning without changing the firmness or feel of your bed.
In general, the taller the mattress topper, the more it changes the feel of your bed. You can choose to make a minor adjustment to your mattress with a 2-inch topper—or more drastically change the feel with a 3- or 4-inch topper.
