For the price this is not a bad chair. It isn't as stable as I'd hoped, but doesn't feel unsafe. The arms pivot up and down but the arm height isn't adjustable and for me they sit much too high. Chair height adjustment seems to work fine, wouldn't mind if I could get it to drop down a bit lower than it's minimum height. There is no seat back incline adjustment per se, only a tilt lock out that either locks it full upright or allows it to rock back and forth. I'd knock it down another star based on all of the above but for the money (I paid $250) it's fine.
