Sturdy but light-weight and comfortable. Adjusts to higher-than-normal seat-height (which I prefer) comfortable arms / arm-height adjustable. Great lumbar support and adjustments as well as tilt adjustments.
Only had the chair for about a week. The first time I sat in it I knew it was "the chair" for comfort. Can not answer on durability because I have not had it long enough. Comfort is great.
The bottom mesh comes separated and falls apart easily within a few months. I have had a warranty replacement and the bottom of that one came undone faster. I will not be getting another mesh chair from staples. Quite comfortable when it is in working order though.
