Very high quality.  If your in the market for a new office chair this was a great option.  Specifically ordered the chair because we have a under-mount keyboard attachment and regular chairs wouldn't fit.  This chair worked perfect with the arms that adjust upward.  The back was very comfortable and most of all, very easy to assemble and very good quality.  The fact that there is lock-tite on each screw added to my assessment of high quality for a good price.
