Thanks for all of the responses. I really don't think that I want to have another mattress with springs in it. What I plan on doing is to put my current mattress in the second bedroom and then get rid of the bed in that room. The mattress in the second bedroom is in horrible shape and I can't believe that my former roommates never complained about it. I'm hoping that I won't have to pay much extra for the delivery people to switch my beds around like this.

Luckily I have several mattress stores to choose from and I think that most of them also have payment plans. Most of the Tempurpedic beds have a 20 year warranty too. I think that both Mancini's and Mattress Discounters lets you sleep on the mattresses for about 60 days and if you still aren't satisfied then you can return it provided it's not stained or in bad condition. I believe that Sleep Train lets you sleep on the mattress for 100 days. I also found a Tempur-Pedic Authorized Dealer which is close to me so I'm going to call them first to find more about their prices/deals etc. I hope to finally get a good nights sleep and wake up pain free soon.
