To start, the chair came delivered without assembly instructions. The screws required for putting the back to the seat of the chair came screwed into the seat. The screws (or the threaded holes) were badly made - they were so tight that after taking them out, bolting the screws back in broke one of my screwdriver heads. Also, be cautious of stripping the screws while taking them out/putting them back in. After assembly, the chair itself is great. The unpleasantness from two hours of frustration with the screws however, was not.
