They came compressed and I thought surely they wouldn't fluff up, but I put them in the dryer on no heat with some dryer balls for half an hour and WOW did they fluff up. They have a lot of fill. They did not skimp. I slept fine with it and would recommend it. I would say it was ok for back sleeping, but excellent for side sleeping. I laid on my stomach for a bit and that felt fine, too, but I don't sleep that way. I have used a down pillow before and didn't like it, but I did like this one.
