Delivery was super fast (unusually so). The chair was very easy to assemble (only two parts plus the wheels) and could be done by one person. The chair feels very sturdy and it's reinforced by metal plates on the bottom (should last many years). The chair is really comfortable for work i.e. sitting at a desk, working on a computer, etc. But is not that comfortable for just relaxing, reading or watching a film. You have to work to keep it tilted back (even at the softest setting) and it doesn't have much of an angle (I would say somewhere between 55° and 60°). So it's just right for office work but wouldn't recommend it for anything else. I gave it 5 stars since it's advertise as an executive chair.
