Common Questions About The Coolside™ Pillowcase

How do cooling pillowcases work?

Cotton, silk, and bamboo are common fabrics for a cooling pillow. These fabrics work in different ways to leave a cooling effect. Some pillows are designed to prevent heat from getting trapped while some materials, such as bamboo, are better to wick away sweat or moisture to keep you cool. If you are a hot sleeper, try a cooling pillowcase today with Coop and receive a 100-night trial with every purchase.

What is the best cooling material for a pillowcase?

Our cooling pillowcase is made with innovative cooling technology that feels cold and silky to the touch. Unlike cotton or silk, the Lulltra™ cool fabric material we use is a blend of bamboo-derived viscose rayon and polyester that is also hypoallergenic and breathable. Bamboo is a great cooling material because it helps regulate body temperature and reduces night sweats by wicking away heat and moisture.

Can a cooling pillow protector be washed?

Yes! The cooling pillow protector is machine washable. Put the pillow cover in the washing machine separately on a cold gentle cycle with mild detergent, and dry on tumble dry low. Be sure to not use bleach or fabric softener, and do not iron or dry clean the cooling pillowcase.
