My mom bought us a new mattress for Christmas 2 years ago and i think I picked the wrong one. My hip is really bothering me (although it was bothering me before I got the mattress) and DH is having debilitating back pain. I am a side sleeper and DH is mainly a stomach sleeper. I noticed last night that the mattress was depressing at least 8 inches where DH was sitting, so I think we need something with more support (he only weighs 170lbs). I slept on a sleep number many years ago at the Ronald McDonald house and didn't like it at all, and I've read that the Tempurpedic can be too hot and take too long to rebound when you move or roll over. Your thoughts? Thanks!!!
