I was able to purchase the chair on sale. It's comfortable was easy to assemble and is adjustable enough so I can get comfortable. This is for use in a home office a few days a week I'm not sure how it would stand up to full-time office use. My only complaint is that the levers for adjustments are not very conveniently located.
This chair did not work for me. I am dealing with Thoracic back spasms and was hoping the lumbar support and back rest would help keep me in good posture. I took the arms off adjusted the lumbar and have used the chair for about 1.5 months now and this chair isn't helping. I also feel when I am typing my elbows don't have as much freedom as I'd like due to the wide back. Even though it has an adjustable lumbar there's something about the back rest/lumbar design that doesn't help keep my shoulders back when seated perfectly.
I've been using the chair for about a week and I'm 100% satisfied. I assembled it myself with little difficulty - everything needed was packaged with the chair including an allen wrench and individually packaged machine screws that were labeled so it was clear where each screw was to be used. As for comfort and functionality the chair seems well-made and is very comfortable - especially the lumbar support. The controls provide all of the settings that I need to adjust seat height tilt and location of lumbar support. I intentionally did not buy the cheapest or most expensive chair that Staples offered of similar styles because I was hoping that this one would provide best value. I was not disappointed!
