The perfect cooling pillows!!
Photo taken after about half of the filling was removed and many months of use. Still my favorite pillows ever!
I absolutely love these adjustable cooling pillows! They keep me cool all night long (must use without a pillowcase for cooling effect.)
They arrived with enough filling to make them super firm and extremely thick. They took several hours to fully puff up. I removed about half the filling to make a more plush pillow which I prefer and they’re still thick and comfy. They offer the perfect amount of support. I’m actually sleeping better!
Bonus: I saved the extra filling and used it to stuff throw pillow covers.

Comfy!
I did have to take some stuffing out for my comfort. After that it is amazing! Love that the pillow is cool!

Great pillow, but…..
I love this pillow for its cooling and adjustability. The only issue is that the cover peels. These tiny nylon thread knots and pulls are annoying in the middle of the night. I do not think it will stop.

These pillows are truly cooling, and they make a huge difference!
These pillows are amazing. I absolutely love them. I’m going through menopause, so I’m constantly hot, then cold, then hot again.
These pillows are truly cooling, and they make a huge difference. I’m a side sleeper, and they are incredibly comfortable. They’re worth every penny, and I highly recommend them to everyone.
