Very fluffy and comfortable.
It only stays cool for a few minutes. It is a very comfortable pillow.

Double Sided Cooling Pillow
Color: Blue, Size: King(2 Pack)-20'*36'
I truly love these pillows. They are sent with extra filling so if their not firm enough you can add more and if their to firm you can remove some. You can make these pillows to your liking. They fluff right back up. Their comfortable and you really get your moneys worth. I love them.

Recommend this product
Color: Blue, Size: Queen(2 Pack)-20'*30'
I bought these for my boyfriend who is a hot sleeper. They are super thick & comfortable. The pillow stays cool & has a great texture. They didn’t have a bad smell. Bought these 3 years ago & they are still like brand new, durable

Good, but not life-changing
Color: Blue, Size: Queen(2 Pack)-20'*30'
These pillows are decent but not amazing. I like that they’re adjustable and come with extra fill, so you can make them softer or firmer depending on how you sleep. The cooling side feels nice at first, but it doesn’t stay super cool all night. They’re comfortable enough, but not a huge upgrade from regular pillows. Good, just not life-changing.
