I could never go back to sleeping on a thick mattress. I used to do 10" of foam, on a 10" box spring. Never again. The mattress-pad I use is 4mm of sponge. I use it to help with air-flow under my body. I think I'm eventually going to wean myself off it and sleep on a sheet on a wooden floor (or perhaps a tatami mat type thing). It helps a lot that I don't have a "steady" love-life. I keep a bed in a guest-bedroom for the dalliances though. Nobody else I've met in real life so far agrees with the concept of sleeping without a mattress. Pity (for them).
