Sunny days and stuffy nights can turn your sleep sanctuary into a sauna. If, like me, you're struggling to sleep in the heat, the problem might just be your mattress. Most mattresses are made from materials like memory foam, which absorb and radiate heat to keep you sweating all night long. 

But you don't have to spend thousands of dollars on one of the best mattresses to rest easy. Nor do you have to drop a couple hundred on the best cooling bed sheets

A cooling mattress protector can solve the problem for a fraction of the price. Though usually just for tackling allergies and keeping your bed hygienic, some mattress protectors have cooling qualities. A high-quality cooling mattress protector is essential for anyone who wants to reap the benefits of sleeping in a cold bedroom without compromising on comfort. 

As H&G's resident sleep writer, I've spent hours researching the top retailers to find you the very best cooling mattress protectors. Full disclosure: I haven't tested them yet, but these lightweight layers won't just keep you cool. They'll protect against stains, spills, dust, and dirt mites, too.

You're on a budget: this is one of the more expensive cooling mattress protectors on the market. 

❌ You're shopping for organic materials: the Bear GlacioTex Mattress Protector is made from a 50/50 polyester and polyethylene blend.

The bottom line

🔎 The Bear GlacioTex Mattress Protector does the job, but you can get better models for less.

The Bear GlacioTex Mattress Protector checks all the main boxes. Made from a 50/50 polyester and polyethylene blend, its high thermal conductivity keeps you cool at night, while its hypoallergenic properties soothe your skin. If you already own a Bear mattress, this protector would be a perfect pick for you. The GlacioTex is fully compatible with Celliant technology: a blend of natural minerals, found in all Bear mattresses, which Bear claims to promote restful sleep. One point to consider: a few customer reviews have reported slipperiness under the sheets. It's also quite expensive for a basic model, so it might be worth looking elsewhere for a premium product that's worth its salt.

Cooling Mattress Protector FAQs

Is a cooling mattress protector necessary?

If you tend to sleep hot, a cooling mattress protector is an ideal solution. An uncovered mattress retains the most heat, and it’s vulnerable to spills, stains, dirt, and dust mites, too. The right cooling mattress protector can combat every one of these, all while keeping you cool. 

What are the best bedding materials to keep cool?

There is some debate as to which bedding material is best. What’s clear, though, is that the most breathable materials are the natural ones, such as organic cotton and bamboo. Adding the best silk pillowcase will also help to keep you cool.

When you’re looking for a cooling mattress protector, steer clear of waterproof materials like vinyl/PVC, phthalates, and PFCs. These are designed to retain heat and will make you sleep hotter.
