I bought this chair our of desperation. After long months of pain in my lower back and back while seating on my dining room chair I decided I needed an office chair. This chair checked all the marks for me: Affordable lightweight good-looks comfortable and easy to assemble. Don't sweat it though the hex key is inside the package..
I really like this chair and it matched perfectly with my new desk. I wish the arms would have been padded since it hurts my elbow when I rest it for a long time but I still like it. The seat has a good cushion and the mesh back provides good support. It was very easy to assemble.
