The chair was delivered on time. The materials are very good and the chair works fine. The instructions recommend 2 people put it together. They are absolutely correct. When they say don't tighten the base to the seat entirely - they mean it. You must just get the screws started THEN line the arms up with the holes on the side and tighten each screw part way. If you screw the bottom plate screws all the way the arms will not line up with the holes and you will have to partially unscrew them. I would have given this chair a 5 rating if it hadn't been so difficult putting it togedther.
