The structure worked very well, only the screws bag was not complete. Since I refused to return because of the costliness and drive yourself to the hardware store had to buy the appropriate screws, I have to pull at this point 1 star.
To chair itself, my feeling is you sit even during prolonged work at the desk very good. The tilt mechanism can be adjusted well and adjust to your needs. For the money, an absolutely convincing product.
