I had a Sleep Number for just over year and after the novelty dissipated, I just couldn't take it anymore. I felt the individual air chambers and it wasn't comfortable at all.

I switched to a Tempurpedic in 2007 and couldn't be happier with it. It is as comfortable as the first night I slept in it.

This post seems a lil bit old. Can we continue again? Dear, I hope you have bought your desirable mattress? Can you tell me which mattress are you using currently? Well my father was facing this same issue, doc recommends him to change his ordinary foam mattress into Hybrid Gel mattress, and trust me after changing mattress he feels quite well and his pain is reducing day by day, If you are still facing the same issue I suggest you must check on BiteMe, because I bought mine one from there.
