Very cool and comfortable pillows. Great value.
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
These pillows are everything described on the site. They do retain shape and don’t flatten out after sleeping all night. They are nice and clean looking and comfortable. The fit on my king size bed is perfect cause I prefer the size to king size. Haven’t had to wash them yet but I have had other pillows with the same material inside and the wash ability is great.

Great pillow
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
The pillows feel great. Being able to remove portions of the interior allowed me and my wife to have a perfect fit. They do stay cool which seems to have helped with my restlessness.

Really Happy With These Pillows!
Color: Blue, Size: Queen(2 Pack)-20'*30'
**Review: Really Happy With These Pillows!** I purchased these pillows and couldn’t be happier! First – they’re cool on *both* sides—finally! I’m not sure why that’s so rare (probably to cut costs), but these actually have cooling material on both sides, and it works really well. Second – the venting around the center helps keep them from getting hot at night. A nice touch that makes a difference for hot sleepers. However, the third feature is the best: the filling. Like many adjustable pillows, you can add or remove the fill, and these come with a small extra bag. The base amount was just right for most people. I had to remove some for my wife but added a bit more to mine. The fill itself is excellent—soft but supportive. You sink into it, but don’t hit bottom. These pillows also have a good weight to them, so they don’t feel cheap. They fluff up great and seem very well made. I followed the recommended dryer run when I first received them and had no odor issues at all. Highly recommend!
