Easy to assemble. Plenty of adjustable bits to get it just right. Seat cushion is comfortable. As a short person (5'2") I don't have a problem with the height of the seat back.
pretty good quality though the connection of the chair to the base allows a small amount of movement even when new so not top-level quality. not a big deal but not a "5-star" piece of furniture either.
The chair is uncomfortable. The lumbar support is a hard piece of plastic that cuts into your lower back. There is no give at all with the lumbar support. The arms are too far forward and too far apart even with the adjustment as far in as it can go. The arms are also hard plastic with no padding.
Replacing a fabulous (28 year old) chair which had failing hydraulics this is pretty comfortable. Very easy to assemble and adjust (seat height lumbar tilt and arm rests). Only drawback compared to my (very expensive) old chair: the armrests adjust vertically and spread out but do not adjust to be closer to my body. The seat is fully cushioned and the back is great. The casters are almost too movable on my wood office floor. Worth every penny.
