The chair assembly design is one of the most difficult I have ever experienced. 
I need to spend more than 1 hour just to put together 1 chair, because the way to tighten the screw is VERY difficult!
Moreover, the cushion part cannot be firmly attached to the wood frames. 
Also, some piece of wood is missing from one of the wood bar I have (see pictures).
Finally, the back of chair is poorly finished and can hook some nice clothes and damage the clothes.
In sum, beautiful on the surface but POOR design.
