I'm sure you can find a way. "honey, could you put this on the table for me? Honey, could you take out these screws? Could you snap this in there? Honey, could you carry this down stairs?"
Just roll it down the stairs, it probably won't damage it.
well it is here, and I slid it down the stairs. the way it was packed I probably could have rolled it down and not hurt it. one hell of a good packing job.
