My mattress got rattily old and uncomfortable, so I swiped Kathy's spare (she has a triple sleeper), which was new and shiny.
Over the next three months my pelvis seized up such that I couldn't walk normally.
I reverted to the old ratty one (on top of hers, which makes it less uncomfortable), and now I can walk again.
My conclusion is that the dominant theory that firm mattresses are good for your back assumes that a) you're male and/or b) your edges are straight. Possibly c) you sleep on your back. I'm very glad indeed that I didn't just go out and buy one.
But I've subsequently gone and lain on them in a bed shop, with someone to assess how straight my spine is, and it turns out I can feel which ones are too firm because they put pressure on my thigh. I haven't quite got around to buying one yet, but I'm going to go for the middling memory foam. (And if that doesn't take, a significantly more expensive one the details of which I forget, but I'm not going to start with significantly expensive.)
