The bottom line

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.
Final thoughts
A longer-term solution to better sleep is to invest in one of the best cooling mattresses. A mattress protector should only be a temporary solution. If your mattress has seen better days, and you have the budget to upgrade, a new model could be the key to a good night’s sleep.
