Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!

Better then the fake down style pillows

These shredded memory foam pillows are really comfortable. They’re soft but still supportive, and I like that you can adjust the fill to get the firmness just right. They don’t go flat easily and hold their shape well through the night. Definitely a nice upgrade if you want something more customizable than a regular pillow.

Best pillow!

Size: Upgrade Queen (2 Pack)

They work!! My husband and I get really hot and it has kept us cool and I have been sleeping all night since I bought them. Will definitely be buying again! The size is accurate and perfect. It gives me great support for my neck. I don’t wake up with my neck hurting and no headaches.
