For the price you can expect more

100.- are not the world, but I have already bought at the price significantly wertigere seating.
Both in the quality of the upholstery, and in the mechanical system.
The instruction was part of a different model, that is, it was initially a little screw and washer counting hip and the holes are not 100% exact fit. For this makes the metal bracket of the backrest the impression as if he had stumbled found for metal mechanical height adjustment - really belong together does not look it. (A part is arched, the In Liegene's plan ... but if you put on according to the screws that holds that ...)
The plug-in connection between the seat and damper acting anything but trustworthy and resilient.
Next I will not complain. The end user is the object of purchase "cooool" and will not bring enough weight on the chair to him - seen on the planned service life - to inflict serious harm.
For heavier adults I would not recommend this chair.
