I always have used feather bed toppers or the ones without actual feathers and it always left big humps and dips in the bed. I was always fluffing them. This is sooo soft and molds to your body. You can actually see the foam reshaping after you get off of it. The cover it is in is soft as well. It unzips for washing. I have removed all the other toppers off my beds and replaced them with this. Very satisfied!!!
