One chair was perfect in every way.  The second one was definitely "used" and returned by a prior purchaser. The hardware was not in its original packaging and was already placed on the legs (incorrectly, according to the instructions) when I received it...the legs were battered/scarred...and the hole for the grounding screw was in the wrong place so I could not tighten it.  I had to have someone come in and fix the problems, which he did, and now it is fine.  But it was a lot of extra work and anxiety to get it to an acceptable level.  I didn't want the hassle of returning it, but the purchaser before me obviously did return it as unworkable.  I would expect Wayfair to give me a partial credit for this damaged purchase.
