Really liked this out of the package, not like traditional feather bed, was fluffy and nice!  Then I slept on it (for about 2 weeks now) and it has valleys where I sleep, I can't shake them out and even if I do they come right back when I lay down.  So there is a big "hill" in the middle of my king bed. I may try switching it around but I really don't think that is going to help. I am average height and weight. Valley's are noticeable through my comforter when I make the bed too.  Pretty disappointed :(
