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!

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.
