We've had to send back two of these, because of manufacturing defects in the back pieces.  The metal on the first one wasn't welded very well, and came apart.  The metal on the second one was gouged, had very sharp edges, and was bent.  We're now waiting for our third chair, and honestly I don't have high hopes.  Apparently there isn't any quality control on the manufacturer's end.  This isn't Wayfair's fault, as they have said they don't open the boxes to inspect the items, they just ship as received from the manufacturer.  Buyer beware if you order this item.
