The office chair is very comfortable and versatile adjustable. I have tried several office chairs before buying and have to say that no one else in its price range is so convenient. In the combination of black / silver he looks also very nice. In a test of the office chair was evaluated on the basis of lateral risk of tipping and a sharp gas spring with flawed. This assessment is understandable for me in any way. I've tried it myself ... it just does not tilt to! Sharp-edged, the gas spring is not. For me, he was just the best!
