These look great at my bar, I ordered 3 of them.  The sale made the purchase an easy one to make and I'm happy with the result.  I read the reviews before I assembled them, so I made an effort to not over-tighten any one of legs as I attached each one (I was working on this alone).  Still, 2 of the stools have a little unevenness to them.  I believe the other reviewers that say it helps to have a person sitting on the stool as the legs are tightened.
