At the moment, I can tell you that the GhostBed Mattress is very comfortable. My back from working so much today is sore in several places. I am going to raise the bed to see if I can get the pain to diminish. Already took an Aleve. I have two small dogs that have already been on the bed. I do have one concern with my young dog though. I have to figure out a way to attach the power to the bed so he can't chew on the wires or the power base.
