I've often wondered if sleeping on the floor is better for your back.
Because of how poor I grew up, I slept on the floor for most of my life until I went to college and started doing it again after college. Of course sleeping with someone else means sleeping in beds again, but I can generally sleep on a floor just fine. Most people will end up complaining about aches and pains when they do.
I don't have any evidence for or against it, but I personally generally feel better when sleeping on the floor.
