I've only been sleeping on my new mattress for 10 days, but so far I love it. It does take a couple days to adjust from an inner spring to foam mattress. It's fairly firm, but I've decided that's a good thing. It's a lot firmer than my old mattress and at first I wasn't so sure I liked that. I can tell I'm getting way more support from it so that is good. I do still think I'd like it a little bit softer/more plush.
