Be sure to follow the rule before you head out.
Rule: You must post before you leave.
IIRC the thing that causes long term damage is staying in the same position for long periods of time. Without a back rest, there isn't much movement you can do to change position. I could be misremembering though
Edit: of course you could just stand up every once in a while and that'd probably take care of it I guess, I'm not an Orthopedist
