I purchased this chair as a graduation gift for my sister. Since she has some back pain I took her to the store and had her select the chair. Upon sitting in this one and realizing the benefit the lumbar support provides she quickly choose it and is completely satisfied even now after several weeks. It was shipped to her home the day after I purchased it as promised by the store employee and it was simple to assemble. I'll definitely return to Staples the next time I'm in the market for a new desk chair.
Having been an office worker for 25+ years this is one of the most comfortable chairs I have had. The lumbar support is the best for sitting extended periods of 8-10 hours a day.
This chair has adjustable height and tilt and the arms can be raised/lowered a bit. The lumbar support can slide up or down a few inches along the back of the chair. The mesh is very firm but comfortable. After I started working from home in March I realized that my home desk chair was not cut out for an 8-hour day. This chair is very comfortable not hard to put together and my back's not hurting at the end of the day anymore. If you can get to a store I suggest trying it out.
