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.
