Very comfortable to sit in for mfg's recommended period. All mechanisms work fine and as advertised. Would recommend (probably will increase price) that lumbar support be adjustable but not a show stopper. Good value.
Chair didn’t break yet and wasn’t hard to assemble. If you are over 5’10 it might not be great since the hard plastic part of the headrest makes contact with your neck. If you are interested in this chair wait until the price falls to $150 or lower to save a lot of money on a fairly price chair!
