Innovative Cooling Technology

Woven in a slick, silky jacquard weave, our exclusive Lulltra™ Cool fabric is 1.5 times denser than our standard fabric. At 400 gsm, this heavyweight fabric maintains a cool and comfy feeling while wicking moisture and body heat away throughout the night.

No Additional Case Required

Because of our fabric’s specific qualities, we suggest you sleep directly on your Coolside™ Pillowcase. Plus, the modern jacquard pattern, neutral grey piping, and sturdy closure make it perfect-looking on its own.

A Cost-Effective Solution

Cranking the A/C isn’t great for your bills—or the environment. By instantly cooling your head and neck, you’ll be able to fall asleep faster and dream of Christmas in July. Plus, the Coolside™ Pillowcase enables you to get the comforting and supportive benefits of memory foam without all that heat.

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.

My husband loves it!

We got this case for him because he sleeps hot, and our pillowcases suffer. He loves it, and just mentioned how - after he’d inadvertently slept on the wrong side of the case - he woke up hot. So thumbs up - success! Thinking of getting one for me now!

I'm Now a Cool Sleeper

I was always a very hot sleeper. I always woke up drenched in sweat. The coolside pillowcase turned me into a cool sleeper. I no longer wake up all sweaty anf actually pretty cold. This pillowcase works really well. Definitely recommend this pillowcase for hot sleepers like I used to be.

Pillow talk

I loved it. I didn't know that there was only one cool side though. I used to flip my pillow to get the cooler side but that doesn't work the same way now. I'm curious how that actually works.
