Working at home, I bought it a year ago an office chair entry level, synthetic leather, armrests and height adjustment for thirty euros. It is still in good condition but was not designed to spend 8h / day sitting on it. So I decided to switch to the higher range. After an initial search in the leather armchairs 'kind CEO / Manager', I finally saw this model. The brand in general and the particular model appears to have good reviews on Amazon for the price is slightly higher in my initial budget but still reasonable, especially compared to high-end models. Fast delivery, packaging neat, very simple assembly (pre-mounted, maximum 15 minutes) and, for the moment, absolute comfort, even in the late afternoon. The settings are numerous and simple (switch seat / back with possible locking, height & depth armrests, seat height & depth, height & tilt head support), the materials seem high quality and rollers 'carpets' delivered work fine my tiles (no need to buy the casters hard floors I think). I am very satisfied and after nearly a week of use, still did not find a valid reason to assign a score lower than 5 stars. So allow me to recommend it highly to anyone wishing to improve their working day comfort.
