Ordered two of these chairs for our office to provide some seating to anyone who may be visiting.  They are very large chairs.  Must bigger than I expected, but this is only an issue for those with small spaces.  I noticed that one came with 2 additional screws for the back legs and the allen wrench while the other did not.  I did not install the screws and had my own allen wrenches so there were no problems there.  I haven't had any issues from not installing the screws, but will laugh at myself if I topple over one day.  

The chairs are gorgeous.  I often catch myself looking at them with appreciation for how they are helping tie the room together.  They are not the most comfortable things in the world, but I do not expect many to be sitting in them continuously either.  Buy them for their visual appeal.  Keep them for their quality.

Pros: Easy assembly.  Beautiful material.  Eye catching
Cons: May be bigger than expected.  Missing  (optional?) equipment.
