8 Best Cooling Mattress Toppers for 2025

With over 91,000 five-star ratings on Amazon, this plush pick is indisputably one of the best cooling memory foam mattress toppers on the market. Available in two thicknesses and a bevy of mattress sizes (ranging from twin to California king), it’s made of CertiPUR-US memory foam that helps relieve pressure points and prevent tossing and turning. Even better, this topper is infused with a cooling gel that helps to capture excess body heat and redistribute it to keep you cool and comfortable.

“The gel infusion not only adds a touch of coolness but also prevents overheating,” says one buyer, “I no longer woke up in the middle of the night feeling like I was trapped in a sauna. Instead, I enjoyed a pleasant and undisturbed night’s sleep.”

Made with a soft rayon cover and unique ventilated back, this gel-infused memory foam mattress topper is designed to optimize airflow while you sleep. That means you’ll get a refreshing night’s rest that won’t feel stuffy or sweaty. You can choose from 2-, 3-, or 4-inch options, each of which comes with a secure strap at the edges to help keep the topper in place.

Customers also love the Goldilocks softness of the memory foam, which lends support while still softly cradling the body. One happy buyer even likened it to “sleeping on a luxury hotel bed every night.” Our favorite part? The soft bamboo-like cover that unzips for easy washing—genius.

The first thing you’ll notice about this cooling mattress topper is the soft quilting that covers the top, which is packed with a state-of-the-art fiberfill that mimics the feel of goose down—and that’s not even the best thing about it. The design boasts Nanatex Coolest Comfort Technology, with a fabric that helps balance and distribute body heat. It’s treated with moisture-wicking technology, too, which allows it to dry faster than cotton—so if you do sweat, it won’t stick around for long.

You can’t choose your thickness like the memory foam options on our list, but this pick does come with plenty of great features, like extra-deep corner pockets, which customers love for keeping the topper in place.

There are plenty of elements that can contribute to a mattress’s cooling effects, but did you know that graphite is one of the most popular? This topper from Saatva is infused with cooling graphite, with an impressive 3 inches of pressure-relieving memory foam that helps relieve pain and reduce motion transfer. This pick is more of a splurge, but the quality is evident in every inch—from the secure straps on the corners to the organic anti-microbial cotton cover.

(Bonus: If you purchase through Saatva’s website, you can even take advantage of a 180-night home trial to make sure you love it before fully committing.)

You know that feeling when you roll over in the middle of the night and find that perfect cool spot on your pillow? Consider this the mattress pad version of that bliss. Developed to help sleepers maintain the ideal personal comfort temperature (which they deem 37.5° Celsius—hence the brand name), this mattress topper boasts a diamond-pattern surface that adds just the right amount of plush while also releasing excess heat and humidity.

Even better, the underside touts waterproof lamination, which will guard against any fluids to help keep your mattress in tip-top shape.

When you share your sleep space with another person, it can be challenging if you prefer a different sleep environment than them. Luckily, with this clever Sleep Number addition, that bedtime battle is a thing of the past.

With half-queen, half-king, and half-California king sizes, this lightly padded addition nestles around the mattress on one side to allow the user to sleep 35% cooler or warmer, depending on their desire. Snoozers can choose from multiple temperature settings and enjoy an automatic shutoff that can be set in one-hour increments, up to nine hours.

If cloud-like comfort is at the top of your priorities, then you’ll want to click “add to cart” on this ultra-padded mattress topper from Sleep Zone. With fluffy quilting in a mix of waves and diamonds, this overstuffed option features NANOTEX technology, which helps the material wick away moisture and keep you dry.

With over 19,000 five-star reviews, it’s beloved by sleep-conscious consumers, who praise the tight fit, breathable material, and durable design that wears well wash after wash.
