Well, I've had this mattress about 1 1/2 years, and long term, it doesn't seem to be holding up too well. Foam is starting to get spongy, and it is losing its ability to spring back. It just seems to be wearing out quickly. I'm not that heavy, only 180 pounds, and the only one who uses this bed. I rotate end to end often, this seems to help for only a short time, then the spongy, non bounce back feeling returns. I contacted Overstock about warranty coverage, and it took what I think was too long to address the warranty question. They passed me off to the manufacturer, who stopped conversing with me when I told them it was a complete mattress, and not just a pad. Additionally, the mattress has to be returned to the manufacturer under warranty, at your expense. Just exactly how do you return a full size, floppy product? If it's returnable at all, it would probably cost a fortune! This thing weighs 60 plus pounds. So, the way that it looks, my initial review came too soon after getting the mattress. Nice at first, but I think it is going to end up in the landfill within 5 years. Too much $$$ for too short of a life. My regular mattress lasted 20+ years, and I'd still be using it if it were softer. Think twice before buying this! In this case, you almost get what you pay for. Now I know why the name brand cost so much.
