I purchased this for my craft/sewing room because of its mobility, lumbar support and flexibility. I have back issues and this chair seemed to fit the bill. It was easy to assemble with all the supplies, tool and instructions. But I found it somewhat uncomfortable for sitting for long periods of time because of the angle of the back which was supposed to be adjustable. It is not. There should have been instructions on how to make adjustments. I will still use it for short projects, but am disappointed.
