Oh my gosh I love these pillows. They are soft and foldable but puff right back up when I get up. If you want a pillow that will stay flat and in the same position you left it in this is not the pillow for you. I read a lot of the reviews and so far haven't had any of the problems other people had, Knock on wood lol. There was a smell the first couple of nights,but I used them anyway. If you just let them fluff and air out for a couple of days before using it may fix the problem, I just didn't want to wait. They are only 2 inches thick when first opened but just fluff them and let them sit a few hours and they puff up nice. So glad I bought them.
