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.

Try a different pillow
Size: Upgrade Queen (2 Pack)
Even with all the memory foam in it, it's still flat. No firmness to it. I hoped it would expand and settle in the few weeks I've had the pillows, but nothing works (dryer, fluffing, etc)
