Bolt holes on bottom of seat were not pre-drilled big enough for the 4 screws to go in all the way. Almost impossible to hand tighten if you do not have strong upper body. I’m a 6’3 male and i could not get them all the way. Electric drill will not help in this situation. Very frustrating. That being said the rest of the assembly process was fine and the seats are comfortable and nice. The fabric is more of a weathered look more than I realized but I think it will be more forgiving for wear and tear. Swivel feature with seat automatically going back to the middle is nice.
