I found these a little annoying to put together properly balanced.  The way the legs, the ring support, and the swivel plate all have to line up perfectly in order to not wind up with rocking chairs.  Other than that, I'm fairly certain two of stools I received were re-packs.  Oddly enough, the one that wasn't was the hardest to balance.  All that stated, they do their job and there's not too much to complain about.
