Hi. I was looking into buying the Bob-O-Pedic from Bob's Discount Furniture. Is this a wise purchase? My wife and I both have very bad backs so we need a good bed. I am skeptical because there are a lot of shady clauses in the warranty ("Goof Proof") agreement. How is the quality? Is it a good warranty? How does it compare in quality to other tempur material beds and other beds in general? Thank you so much in advance for the help.
