Pillow explosion
Color: White, Size: King (Pack of 2)
Pillows were extremely comfortable until one exploded while sleeping.Otherwise it would get 5 stars. Having to return kind of a pain. As they come compressed.

Not for hot sleepers
Color: White, Size: King (Pack of 2)
They’re comfortable and keep their shape, but they are not cooling pillows. 10 minutes after laying your head on it. You can feel the heat radiating back . I wake up every night with my head soaked with sweat.

Good set
Color: White, Size: King (Pack of 2)
Soft and fluffy! I like the ability to add or remove filling via the zippers. All pillows should have this!
