I took a chance buying this because there weren't many reviews and I didn't see any similar chairs locally that I could test. I was very nervous because I tested the similar looking chairs with the lower back and hated them.
For the price, I LOVE this chair. It looks great in my office. Even though it is bigger than the office supply store black chair I had, it looks like it takes up less space.
I work from home 2 or 3 days a week, often for 10+ hours and haven't been uncomfortable in this chair. I'm 5' 11" and the chair height is good for me.
My only complaint is that because I have it at maximum height the arms scrape the underside of my desk from time to time. Not sure if this is the chair's fault or the desk height.
Minor annoyance for a chair that helps me keep a home office that functions, supports long hours of computer time, and looks stylish - especially since mine is downstairs and does not have a door I can shut to hide the ugly.
Would absolutely buy it again.
