I am very satisfied with the chair. The first I bought about 2 years ago. I have used it approximately 18 months a day and also frequently taken on longer trips. When the time has elapsed, the linkage and the hinges was undamaged. The cover showed the front edge some cracks and was a little scuffed. The chair, however, was still stable and with my body weight of 110 kg. I then left the unit in Lebanon where I worked my remaining colleagues there 1 year, to reduce the weight of my luggage. Immediately after my return, I have ordered the chair again, get back delivered promptly and am still very happy with it
