I have been using this chair for over a month now and more often than not. I honestly have to say that it is not in the same shape as it was the first week I used it. The hydraulic mechanism seems to be loosening a bit. It does not seem to keep the height that you set it at for very long. The color is perfect and is easy to assemble. It came with a minor scratch on the side where the mesh meets the frame but nothing to worry about. At the beginning yes, it was just what I needed after a good month and a half not so much. The quality seems to be rapidly decaying. I forsee that maybe in the near future I will have to get a new one even though it is ergonomically good, it seems to be failing as it also has become a bit wobbly. The only way to keep it from being so is to tighten the back so it does not spring back at all. So that feature is no longer usable. It is OK but don't expect it to last or being good to your back for the long run.
