The 12 Best Cooling Pillows of 2025
The Casper Hybrid Pillow with Snow Technology is the coolest pillow I have ever tested. That’s why it takes my pick for the best overall cooling pillow. Not only is the machine-washable cover cool to the touch but the inside of the pillow is made with perforated poly foam, polyester fibers and gel. It uses what Casper calls Snow Technology, which has phase-change material that remains temperature-neutral around your head and neck and allows for airflow.
The pillow is soft yet supportive, and I like how my head sinks a little into the poly foam — but not too far. In terms of firmness, I would say it is medium, and when you press your hand into the material, it returns to its original shape a bit faster than memory foam does. So no need for fluffing. The Casper Hybrid Pillow will support back, side and combination sleepers (those that switch between positions at night).
Sleeping position(s): Back, side and combination
