Mattress shopping!

We had the same mattress for damn near 15 years....thing was horrible. We both have a truck load of skeletal/arthritic issues. We bought a Tempurpedic, don't remember the exact model, a couple of years ago. Most comfortable bed I have ever slept in. I do wake up with slightly less pain that I had prior to getting it...but far from the "life changer" many folks claim it is.
