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 heat away from your body throughout the night.

No Additional Case Required

Because of our fabric’s specific qualities, we suggest you sleep directly on your Cool Side Pillowcase. Plus, the modern jacquard pattern, neutral grey piping, and hidden zip 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 Cool Side Pillowcase enables you to get the comforting and supportive benefits of memory foam without all that heat.

Cool comfort

Totally enhances my Coop pillow experience! Takes away that constant flipping of my pillow to find the cool spot! Love it!

Love this pillow cover

The cover does what it says and has a cool side plus a more cozy side. I sleep directly on this cover without another pillow case. The cover is pricey but I’m happy with my purchase and actually bought two.

Cool but warms quickly

I love the cool side of the pillow. And it is wonderful when I first lie down on it. It just heats up quickly. But I just have to slide over to another cooler area.

It's chilly!

Love this. I'm hot-headed - literally. But it's a problem because I like being cold when I sleep. I was skeptical about this, but glad I bought it. When I lie down, it instantly cools me. Like other people said, it doesn't stay cool, since my body heat inevitably breaks down the "cool", but I can move over and get a new cool spot. In the event I'm cold, I can just flip my pillow over to its non-cooled side.
