The chair is just what I wanted, looks just like the photo. Fits at my desk, is comfortable and is easy to assemble. The hydraulic mechanism for making it go up and down works well.  I gave it 4 stars because the packaging was not secure. The littlest pieces, the washers, were loose inside the box, and some were missing. I later found one on the driveway, so it apparently fell through a crack in the box.
