  Astronauts are weightless and can sleep in any orientation as there is no gravity (no up, no down) They do strap themselves to wall, seats or small beds, otherwise they would just be floating around bumping into things.

  Yeah, and I saw this design for a cylindrical bed that is padded all the way around to use in space. I imagine space beds to be more comfy than regular ones.
