What I could not see from the article description, however, is very unique for a chair and important for the seating comfort:
.) The seat can be moved longitudinally. I have very long legs and, for example with a German wannabe Premium armchair brand which stands on a star remembers almost all office chairs feel that I down case the same because only the butt on the chair takes place and at least the front half of the upper taverns in the air / depends.
.) The armrests can be varied adjust: Up and down is standard. They can continuously back and forth and left and right. In addition, the armrests can rotate based on a grid to the left and right.
For this price range I have these possibilities yet found in any other office chair.
