JP… I’m not sure how you have your tempurpedic set up, but if you have it on a box spring type platform, you may want to throw it on the floor and try sleeping on it that way before making any rash decisions to toss it. My brother has a TP on a box spring and his is MUCH softer than mine. Too soft in my opinion. I have a classic on a custom bed frame where the mattress sits directly on a 1.25″ thick MDF deck, essentially a rigid platform. Setup this way it is actually quite firm… more so than other mattresses I can remember sleeping on. She_Said also has back issues, and swears by our tp setup on MDF.
