Excellent price / quality - a bit tedious editing

As for installation, as indicated in other reviews, this can be quite painful. I highly recommend to spray a squirt of WD40 in each of the threads to be patient enough to engage the ten screws (for chair) one by one, being careful not to over tighten as the screws were not individually committed to but 4 or 5 turns. Once a screw strength is a hassle because the keys provided and the imprint 6-point screw heads are of poor quality, which quickly "to machine" to each other and if we must force !
The first two chairs, I really mad, but I've improved (especially the use WD40) to As and the last chairs were really quickly mounted!
