This set is horribly manufactured- the chairs are impossible to assemble as the backs do not even come close to meeting up with the holes drilled in the supports you have to attach them to and no length of screw will get them to fit together. Even if you were able to force a much longer screw than came with the set into the chair back, half the screw would be visible between the support and the back itself. We requested a replacement set of chairs since these were defective, and the second set we were sent had exactly the same issue. It was very frustrating and throwing away 8 useless disassembled chairs feels irresponsibly wasteful but there is nothing we can do with a bunch of half chairs. Luckily, Wayfair has excellent customer service and provided a full refund, but it was still a very frustrating experience and after several weeks of this ordeal we still don't have a dining set.
