What's the difference in a pillow vs a pillow cover?


Pillow

Pillows should be replaced at least every year. Ideal for those who need to replace their existing pillow and need temperature regulation performance.

Pillow Cover

Ideal if you have a pillow you love, but need it to sleep cooler. Pillow Covers extend the lifetime of your pillow and can be paired with our pillows for extra temperature regulation performance.
