The heat dome that’s baking the central and eastern US is bringing the hottest temperatures we’ve seen this year. Hot sleeper or not, there’s a good chance you might be looking for some relief at night. When flipping pillows and rolling over to find a cool spot on the mattress doesn't work, you might need some cooling technology.
A pillow designed with cooling technology can be a game changer, especially if its tech extends beyond a cooling cover into the pillow's stuffing or foam. To find the best one, I tested dozens, considering each pillow's cooling sensation, material, feel, firmness, sleeper type, price, size and different sleeping positions.
The best overall cooling pillow
The Casper Hybrid Pillow with Snow Technology made the top of my list due to its high-quality materials, comfort and truly cool-to-the-touch feel. The innovative materials used in this pillow include Casper's unique Phase Change materials, HeatDelete bands and a CoolTouch Cover, all actively working to keep you cooler throughout the night.
I tested 25 cooling pillows from 20 top brands; the 12 pillows that made this list are the best cooling pillows on the market. I also included a few honorable mentions that might work better for your particular sleep setup.
Best cooling pillows of 2025
Caroline Igo/CNET Casper Hybrid Pillow with Snow Technology Best overall cooling pillow $104 at Amazon 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 Pros: Cool to the touch; coolest pillow I tested
Soft, machine-washable cover
Four layers of foam, fiber and gel with Snow Technology Cons: Over $100 for one pillow
