The assembly of this chair was slightly inconvenient as I was trying to align the screw holes which took some time, although the entire assembly is straightforward. However, the chair itself is good and helps with my posture. When getting off the chair it raises itself slightly which I find to be a minor inconvenience, however I can handle this and it only seems to occur at the maximum height; this is the same as my old chair. The maximum height this chair raises to, for me, is perfect. I bought this chair because of its features and it has been AFRDI 6 certifed. Furthermore, it has a 10 year warranty (excluding upholstery) which is another reason I purchased this. I recommend this chair as it is reasonably priced.
