Great pillows! Nice & fluffy with plenty of support for side sleepers yet you can squish them down if you need to for back sleepers. I am both a side & back sleeper & used to switch between 2 pillows at night. This pillow replaces both of my other pillows & I sleep great. Oh I forgot to mention I have suffered with a severe neck injury for 24 years now so proper head & neck support is critical for me. The only problem I have is 1 out of the four pillows is a bit less fluffy or flatter than the other 3. I havent contacted customer service yet & may not as I may give it to my 5 yr old daughter.
