OK, the chairs came today and I was a little worried based on the 2 previous reviews, but I did manage to get them all together. That said, the code they used to label the pieces made little sense, so it became more of a trial and error exercise. The good news is you only need one tool, but if you try to use that little Allen wrench that’s included, you will probably be quite frustrated. I got a screw gun and Allen bit that made the the job much easier. However, be careful not to over tighten. Also, I found a rubber mallet to be useful, as not all pieces went together easily. Lastly, be sure to have a Workmate or work bench which also makes the job a lot easier. Maybe just pay Wayfair the 100 bucks or whatever it is and have them come preassembled. In any case, they didn’t go together easily but they did go together and only a few expletives were needed. They look cool and we are happy with them. By the way, the picture shows them with the color on the chair backs facing the front of the chair. I thought they looked better with the color facing the back.
