I had a feather mattress topper that never stayed in place and did not help with my degenerative disc disease or arthritis so I ordered this mattress topper to give it a try. What a difference! This topper fits my queen mattress perfectly and stays in place, even with a 90lb dog jumping up and down on the bed. The comfort level is Awesome!! I have less problems with pressure point pain and can rest more comfortably. Definitely recommend.
