The parts were not labeled and thrown in a bag, I had to put all those nuts in a line to determine which was which (over 90 screws, bolts, and fasteners). Not all bolts were included. One chair was defected as one of the three bottom chair rods was not welded to the frame as the other three and the same chair screw mechanism was severed, so the bottom leg screw kept falling out when I put it upright. I contacted Wayfair and the manufacturer, and they both said there isn't anything wrong with the chair even though I sent photos showing the problems. I am waiting for a second response from them now. The other pieces are fine.
