I have received this chair recently and its really awesome and strong. In this price range I have not expected this great quality. Is very comfortable for neck and back. We can get rid of the back pain and  sit on this chair for longer timers easily without stress. 
I am using this chair with my study table for reading for longer times on this. Based upon the experience with this chair for this last 3 days its really great and comfortable. I would recommend this chair to all of you for studying or office use whoever sits for longer times on chairs.. Just go for it.. Its perfect..
