Whether you're a hot sleeper or live in a warm climate, heat can have an impact on your sleep. While you can always turn up the air conditioning, bedding accessories like cooling mattress toppers are an easy way to improve your setup and ensure you have a comfortable night of rest.

"Body temperature plays a big role in sleep quality," says Lindsay Little, vice president of regional sales at Mattress Firm. "Higher environmental temperatures make it harder to sleep because it affects your body's ability to regulate its internal temperature and can cause you to have disrupted sleep and reduce the quality of REM sleep."

To find the best cooling mattress toppers, we researched a variety of picks, keeping in mind each pick's material, thickness, and care instructions. We also consulted Lindsay Little, vice president of regional sales at Mattress Firm, and Dr. Peter Polos, MD, Ph.D., FCCP, FAASM, sleep medicine specialist, and sleep expert at Sleep Number.

Overall, the best cooling mattress topper is the Tempur-Pedic Tempur-Adapt + Cooling Mattress Topper. The mattress topper is made with memory foam that adapts to you, offering significant support.

Here, the best cooling mattress toppers.

Why You Should Get It: This mattress topper will help body temperature and is made with memory foam that'll help with back pain.

Keep in Mind: The brand recommends air-drying the cover after washing it which means it may take a bit of time to dry.

Overall, the best cooling mattress topper is this pick from Tempur-Pedic. In addition to a 3-inch thick base, this mattress topper is made with a memory foam material that'll precisely adapt to your shape, weight, and temperature, offering additional comfort.

The mattress topper is offered in six sizes, each of which comes with a washable cooling cover. It's recommended that the cover be air-dried after washing it in a cold cycle, but you can dry it on a cool setting if needed.

The design is made with three inches of the brand's soft Tempur-Es material and is specifically designed to adapt to your body shape, weight, and temperature. As a result, you'll have a more personalized experience while you sleep, making for an even more comfortable rest.

Why You Should Get It: It comes with a remote control you can use to cool or warm your bed. It's also offered in half sizes, so you can put it on one side of the bed.

Keep in Mind: If you use a heated blanket, you'll have to be mindful with this design as both shouldn't be powered on at the same time.

The Sleep Number Dualtemp Individual Layer is an investment, but its advanced technology and unique sizing options make it one of the best cooling mattress toppers worth considering. Recommended by Dr. Polos, the mattress topper is cool-to-touch and will make for a comfortable night of sleep.

Unlike other options on the market, the cooling mattress topper comes with a remote control, so you can make it warm or cool from the comfort of your bed. The remote allows you to choose from three levels: low, medium, or high. You can also set a timer and utilize the automatic shutoff option so it won't stay on while you sleep.

Another unique detail worth noting is that the cooling mattress topper is only offered in three half sizes. Instead of covering the whole bed, these half sizes allow you to keep your mattress topper on your side of the bed, so you and a partner can choose their own comfort level. If the mattress topper doesn't work, however, you'll be able to return or exchange it for up to 100 nights.

What To Know About Cooling Mattress Toppers Before Shopping

Material

When it comes to selecting a mattress topper, there are a variety of materials to choose from. Little advises going for specific materials, like bamboo or tencel, that are known to be naturally cooling. On the other hand, Polos advises keeping materials like memory foam, latex, down, and polyester blends in mind as they provide better support.

Thickness

Most mattress toppers range in the 3-inch thickness size, but there are both larger and smaller options available. According to Polos, the thickness of the mattress topper is truly based on personal preference.

"In general, you should look for something that suits your individual sleep needs and will provide the most comfort," he says. "The additional thickness should be considered when purchasing sheets with a deep enough pocket to accommodate the topper.

Care Instructions

While some mattress toppers may be gently machine washed and dried, many require spot cleaning to keep their delicate materials intact. This is because mattress toppers are typically bulkier and often don't fit into washing machines, so keep an eye out for the machine-washable ones, if that's easier for you.

"Preventing spills, stains, and skin cells from getting into the topper will help it stay cleaner and last longer, so you should put a protective cover over it for good measure," Little says.

Your Questions, Answered

How do cooling mattress toppers work?

According to Little, the material in the cooling toppers pulls energy (heat) away from the sleeper and into the material to maintain an optimal sleeping temperature. While many current mattresses do typically have this already built into them, mattress toppers are a great addition to prolong your mattress or add an additional layer of comfort or support.

"A quality mattress topper offers noticeable sleep results, so you'll want to make sure to try it for a couple of weeks to make sure you're experiencing better sleep," Dr. Polos says.

Can you clean gel cooling mattress toppers?

For the most part, you can only spot clean a gel cooling mattress topper. However, some do come with removable covers, so be sure to read the product's washing instructions to be sure.

How do you keep a mattress topper in place?

In order to keep your mattress topper in place, Polos advises looking for one with anchor bands, which are the elastic straps that stretch around the corners of the bed. Once it's secure, it's less likely to shift throughout the night while you rest.
