Cool, Supportive, and Great for Hot Sleepers
Size: Queen Size Pack of 2, Color: White
These cooling pillows have been a great upgrade for my sleep. The shredded memory foam provides nice support while still feeling soft and adjustable. I like that the pillows keep their shape and don’t go flat during the night.
The cooling fabric really helps if you tend to sleep warm. They feel breathable and comfortable, especially compared to traditional memory foam pillows that trap heat. The queen size is generous and works well for both side and back sleeping.
Overall, a great value for a set of two pillows. Comfortable, supportive, and noticeably cooler than my old ones. I would definitely buy them again.

Great pillows, needs more filler tho!
Size: King Size Pack of 2, Color: White
Partner says it's the best thing that's ever happened and has helped his back/shoulder pain tremendously. I personally think it needs to give you more fluff or whatever the filling is. Because the tiny bag that comes btwn the two was not enough! However, still comfy, filling is nice and fluffy like a cloud.

Very comfortable
Size: Queen (1 Count), Color: White, Size: Queen (1 Count), Color: White
Takes a few minutes to fluff up and inflate after opening. Nice fabric. One side is bamboo and one side is cooling. Looks high quality.
