This is a wonderful addition to our king sized bed. We used a beautiful and comfortable down featherbed for a long time but got tired of "fluffing" it every day. We bought this and have never looked back. I have terrible RA and I wake up stiff but not as badly as before. No matter how restless either one of us are, the mattress topper meets our demands and then some. My only recommendation is to never buy a topper less than 4" deep or you will be disappointed. Thank you. Bought another for our daughter :) P.G.
