The chair was relatively easy to set up, instructions are well illustrated. The only downside: The total of 12 screws with which the backrest and the seat are fastened very cheap. Once positioned incorrectly and rotated and the thread is damaged or even broken. Overall, the chair makes a good impression but, processing and the reference are good. No smell, the seat surface is relatively long, seating comfort is pleasant, the Wippjunktion could have for my taste a little more game backwards. With my 100 Kg I is well fitted and comfortable in the chair. With prolonged sitting, I would imagine that you sweat quickly Leatherette (especially with shorts). All in all a buy recommendation.
