I got this for a guest room so nobody's actually slept on it yet, but I can give my initial impressions. It washed very nicely - no bunching of the filling. The fabric is very soft and, just from laying on it for a few minutes, very comfortable. It adds a slight bit of cushiness to the old spring mattress, although obviously not as much as a foam topper would. It fits my full-sized 11" thick mattress perfectly, but I think it would be a stretch to get it to stay on a very deep mattress.
