Sealy Posturepedic Mattress Review

This is the first mattress that I bought since moving out on my own. My husband and I were given a hand me down mattress so we decided we wanted to buy a good mattress. Neither of us had ever had a really nice mattress so I decided to splurge. When I went shopping for the mattress, I immediately went to the Sealy's because of their reputation. I was interested in the Sealy Posturepedic Archway mattress because I have back problems and it was a little firmer than the others. So they delivered it and set it up and I thought it was nice. My husband came home from deployment two months later and he thought it was "alright". A few months later we decided to flip it because it was starting to indent where we slept. We went to flip it and there was no handles and it was heavy. Then as we were about to flip it, we realized it was only a one sided mattress. So now we alternate it from foot to head but it still indents easily. I wouldn't have bought it had I known it was one sided, which is my fault for not noticing or asking. The salesman told me it would last for ten years but it has been two and we already want a new one. It was more comfortable when it was new. Now it is just indented and my husband hates it. I don't hate it. I think it's alright but it isn't very helpful with my back.
