I searched for weeks for a supportive good looking office chair and after reading reviews settled on this one. Once I decided on the color of lime green from the many options (truth be told, I really wanted turquoise), I made my decision. Assembly was pretty easy, although there are no written instructions, just pictures. Immediately found it very comfortable and really like the fold up arm rests, as they can get in the way on occasion, and it scraped under the desk and the fishnet type fabric ripped a little, so that was a bummer. I still really like it, although the lighter color is going to need cleaning more often than a darker one would have. The back is fixed, but has good lower support, I would recommend.
