The adjustable head rest which was a key factor in my choosing this chair does not work properly. The screws could not be screwed in to allow for repositioning of the headrest. Too much trouble to return it and start anew.
Good quality/sturdy. Very easy to assemble all the holes for the screws aligned with the slots on the components. Especially helpful was the packaging wherein the screws for each assembly step was in a separate pouch and color coded (great idea). Comfortable with adjustments for arm rests height tilt lumbar support etc.
Easy to assemble comfortable office chair. I will say that if you are short this may not be the chair for you. Really like the adjustable lumbar support.
