Many reviewers have noted that chair assembly is difficult, even for skilled handymen/women. Those reviews are correct. The problem is that you have to get 8 machine cap screws (bolts) started into their corresponding threaded inserts, but some of the inserts in the chair parts were installed crooked. This makes it very difficult to get the bolts started without cross-threading (even if you are being very cautious starting them by hand). Also, the bolts and hex keys supplied are of inferior quality steel, so the hex key tends to slip in the cap screw head. I used a better quality hex key set, but the cap screws still ended up damaged, so had to purchase replacement bolts at the hardware store, as no extra bolts were provided. The table went together much more easily, but the headache of chair assembly results in a low rating from me. Beware!
