I sat in about 15 chairs at my local Staples store. I felt that this chair was the most comfortable. I purchased the chair and assembled it myself. It only took about 15 or 20 minutes to assemble. My wife liked it so much she asked me to go buy one for her which I did. We've only had them for a week but so far so good. I hope they hold up over time. The quality appears to be good.
Tried all the chairs at the store and this was the one I liked best. It took me about 15-20 minutes to assemble (the back was the hardest) all the parts were there and the only tool needed was an allen wrench (provided in the box). The seat on this one is a little stiffer than the one in the store but presume that will loosen up with use. All the parts work great lumbar support so glad I got this one.
