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.

Does what it says

It is a cool pillow case. But like most it only lasts so long, I did like that it was a satin like material but my earrings kept getting caught so I had to put a pillow case on it which defeated it's purpose. I returned it.

Love it!

This is a very comfortable pillow and most of all I did not wake up with my head sweating. My hair was just as good as when I went to bed. I also love that I can adjust the thickness of the pillow. Its perfect!

Nice hot/cold, zippers a problem

Have 9 of these pillows and covers, zippers are too small and hard to close, especially after a wash or two. I also sleep with a CPAP and it absolutely shreds this pillow case if any of the Velcro even slightly grazes or touches, needs to be tested with people with beards (short can shred it) and with cpap head gear
