These were a little hard to assemble, as I was warned by previous reviews. The hardest part was getting the Allen key into proper position to get good leverage to tighten the screws. I managed it but it wasn't easy-- it took 30-40 minutes per chair. There was a very slight wobble to the chairs when I finished due to uneven legs, but it's not noticeable when you sit on them. Overall, they meet my needs and look great. I'm thinking of ordering a second set of four.
