Assembly was easy I did it by myself, I have to add I’m 68 years old with arthritic hands and it was still easy.￼ I Assembled two chairs.
The actual chair is comfortable but the padding really needs more cushioning.￼ It’ll be interesting to know how long the padding will last.￼The padding also had unfinished threading on both chairs so there must be a problem with the inspection of quality control.￼ 
Good luck
