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.

Back sleeper here
Size: Standard
So since they were listed as down alternative, I was interested to see if they had that artificially puffy feel to them. They do get puffed up really well after a day. And the fabric is cool and comfortable. I do feel like these have good quality stuffing and the cover feels nice. I'm a back sleeper and it's just the right amount of bulk under my neck. I usually bunch the pillow up a little bit there so there's a little more pressure under my neck but with these it just felt good to lay on it without having to bunch it up in any special way. So I would definitely recommend them. So far I'm really liking having these pillows.

Nice and Fluffy
Size: Standard
These "down alternative" pillows have been a winner for me. Came two to a package and once they have a couple of days our of the vacuum packaging are nice and fluffy with no noticable odor. Just the right amount of "spring" to them for my taste. Also don't overheat my face/neck as traditional down pillows sometimes have.
