These stools are sturdy and substantial. They took no time to assemble. The frustrating and infuriating part, is that the instructions and the seats don't match. The bottom of the seats are supposed to be predrilled with 4 holes, two on each side that attach to the frame. The seats have one hole drilled on each side and one hole in the middle. The holes don't align with anything on the frame. Will be contacting Wayfair.
