Pillows are very full, almost too full for me at first. They have settled in a bit over the course of a few weeks, but definitely have not flattened in any way. They are soft and have a lot of bounce. My only complaint is that one of the pillows seemed to be fuller on one side more than the other and it couldn't be "fluffed" out. It's still somewhat uneven after a few weeks, but not noticeably.
