When I picked up the box after it was dropped off the pieces were rattling around inside.  I opened it and nothing inside had been secured.  I think it had been shipped to someone else first who then threw it all back in the box and sent it back, then it was shipped to me as is.  I also think it was used because the wheels were dirty and there was something oil-like smeared on the vinyl seat.  Having said all that, I put it together (which was easy), cleaned it up, and now I really like it.  It's nice looking, it rolls well, and the neumatic seat lifts and lowers nicely and is comfortable.
