Delivery went perfectly. Assembly also, with the usual handles these "executive chairs". Processing looks as far from ok. Very good, I find that the chair can also be set a little higher than usual. Other seats are not so high even when fully extended spring. It is very pleasant to sit for longer times to change the seat height and so the posture at the desk. The back is slightly curved and fits comfortably on the back. For relaxation, the chair has a rocker.
