How to Shop for Cooling Mattress Toppers
There are plenty of mattress toppers on the market that come in a wide range of materials. Memory foam is by far one of the most popular options, as it's known for being comfortable, supportive, and motion-isolating. However, regular memory foam can often retain heat, which can make you feel uncomfortably warm. That's why all of the memory foam toppers on our list also use materials like gel, graphite, and copper for their cooling properties. Another option is latex, which is a natural alternative to memory foam that's naturally cooling. Latex is typically more expensive than foam though, so it might not be the best choice for your needs.
When shopping for cooling mattress toppers, you'll probably notice that most of them have a height between one and four inches. Thicker mattress toppers are best for people who are trying to even out an old lumpy mattress or add significant height to their bed. Otherwise, you might not notice much of a difference. Just keep in mind that you might need to use deep-pocket sheets with extra thick mattress toppers to prevent the corners of your fitted sheet from sliding off your bed.
Keep an eye out for any certifications that your cooling topper has, especially if you're thinking about getting one that's made of memory foam. A CertiPUR-US certification means that the foam in your mattress topper has a low amount of VOCs (volatile organic compounds) and is made without things like formaldehyde, ozone depleters, and heavy metals.
You can also look for mattress toppers that are OEKO-TEX Standard 100 certified, which ensures that every piece of the product was tested for harmful substances and found to be harmless. Another certification is GREENGUARD Gold, which means the product meets rigorous third-party chemical emissions standards.
Questions You Might Ask
What's the difference between a mattress topper and a mattress pad?
It all comes down to thickness. Mattress toppers are designed to change the way your bed feels, so the most popular options are two and three inches thick. Mattress pads, on the other hand, are much thinner and are designed to protect the mattress instead of altering it, so they won't be able to make a lumpy or uneven bed feel more comfortable.
How should you care for a cooling mattress topper?
Unfortunately, most mattress toppers cannot be put in the washing machine or dryer. That means you'll have to stick to spot cleaning—typically with mild soap and water. But always double-check the brand's recommendations for your specific mattress topper before using any cleaning products. If you're a particularly sweaty sleeper, then it's probably a good idea to use a mattress protector to help keep your topper in good shape.
What else can you put on a mattress to keep cool?
There are plenty of other cooling bedding options that you can use in addition to a mattress topper. Cooling sheets made of breathable materials can go directly on your mattress topper, while cooling blankets and cooling pillowcases add the finishing touches. Just remember that cooling bedding can't change the temperature of a room, so you'll still need to use a fan or window air conditioner when it's super hot in the summer.
