I got a relatively hard foam mattress after I realized that I needed better support for my back (I won't get into how I found that out).
As far as I can tell, it's the best mattress that I've ever slept on. It's hard enough so that it doesn't bend inwards when I put my weight on it, and that keeps my spine straight when I sleep sideways. I tried "memory foam" at the store, but it didn't really seem like it work for that purpose.
The foam mattress has to be hard enough so it supports you without "caving in" too much, yet sufficiently soft so that it doesn't hurt you. The ideal hardness (for me) falls somewhere in the spectrum between a Japanese tatami mat (too hard) and a big sponge (too soft).
