This chair is very comfortable. The head rest is difficult to adjust just right if you're a short woman who wears your hair in a bun. That said the height of the chair and the adjustable arm rests are the most comfortable I've found.
It has several adjustments. Headrest arm height lower lumbar and chair height. The mesh is sturdy and a great color. Chair ia handsome (not cheesy looking). Price was fair.
Involves minimal effort in keeping good posture at a desk. I sat for four consecutive hours with no need to stretch or reposition within the duration and had no aches or difficulty when I stood back up. Each component is customizable to the dimensions of the adult user.
