Very thin & no support
Size: Queen (U.S. Standard)
I was thinking these pillows were going to be kind of firm with the way they are described and the picture but they are very thin and when I laid down on it, it was like whatever is in the pillow just instantly moved to each side of my head. Definitely not for me and my neck issues.
