Let me start by saying the Staples buying and delivery experience was great. I have no issues with it. However this is possibly one of the most uncomfortable chairs that I have ever sat in. I sat in it for a few hours and felt like I needed to go to the chiropractor. This is chair is best for someone who sits in a leaning back position. I tend to sit more forward on a chair with my arms on my desk at my keyboard. Not for me. I am taking it to the office for our meeting room where we don't sit for long periods of time. We need some updated chairs there. Info on me that I found helpful when I was reviewing chairs - I am 5'11" and 160 lbs.
Overall the chair is very comfortable. The only problem is I'm a bigger guy 6' and 350 lbs and my legs are right against the arms of the chair where it meets the seat towards the front. If the chair was more open up front or maybe 3" wider that would suit me fine.
Although it advertises lumbar support...it's a lie. I wouldn't buy this chair again. If you have the opportunity before you buy try to find one assembled in store and try it out.
