I have a sleep Number Bed . Had it about 9 years. I do like it even tho after two years the motor I guess it called air pump went out and cost me $269.00 plus shipping. I thought that was a bummer. I have had six back surgerys and have severe arthiritis and a lot of joint pain. I just don't think it is worth the money. I could have bought three set for what I paid for this. I have a memory foam pad on top of it now.But it cost so much money I don't think I can afford to buy a new one now. That my two cents worth.
