Hi, Thanks everyone for the well wishes. Mary, I followed your suggestion and found 2x1"x24" mattress that I put one on top of the other in the middle of my bed and I was able to sleep without pain last night. I will call the store tomorrow to ask for an exchange. I think I will ask for the softess. My bed does all the positions: head up, feet up, head up and feet up, head up and feet down, head down and feet up. I keep it flat normally but when I go to bed with Amatine still working I lift the head until the Amatine wears off.
