Save your money and purchase something different. I started a new job and they were so excited that I was getting a new chair but both me and the other person who got one are suffering with back pain trying to stay comfortable and balanced with the lean.
I looked at quite a few chairs for my desk. After comparing many items for their width seat depth and height I chose the Turcott chair for its construction its features and its comfort level. I can sit in it for may hours without the back pain my last mesh chair gave me. This chair has lumbar support for my lower back and fixed arm rests at just the right height. I would recommend this chair to anyone.
