Believe the other reviews that say how horrible assembling these chairs are! The holes in the legs and chair DO NOT LINE UP! The holes in the legs are lined with metal grooves that should help guide the threads of the bolts, so you can’t re-drill the holes. It took me 10 hours to assemble 4 chairs because the holes do not line up, I had to put extra effort into screwing the bolts into the misaligned holes. Each chair has 8 bolts and an Allen wrench is provided. If you can use power tools, assembly may take fewer than 2.5 hours per chair. One leg is supported with only 1 bolt because the hole in the chair did not line up with the hole in the leg AT ALL! My fingers were sore during assembly and for the whole day afterward. The cushions are very stiff and uncomfortable.
