I’ve been sleeping on the floor for over 6 months in my own house. I guess I just figured, cavemen slept on the ground and they survived, so my floor is a step up from that—no rocks or dirt or bugs. My back never complains and I when I wake up, I still never want to get out of ‘bed’ just like I felt when I had one. I should eventually get a bed though, especially if I ever plan on putting a wife in it.
