Beautiful build quality, well-conditioned, well protected in its box, easy to assemble (even only). The assembly is facilitated by a clear plan, missing kidneys (it even has 2 more bolts) and following the instructions in 20 minutes the chair is mounted. We bought two, one for my wife and one for me, everyone appreciates comfort, height adjustment, tilt, while we do neither the same weight nor the same size over the wheels are of good quality and very quiet. Finally this chair design is the most beautiful effect with a quality / great price. I recommend this product.
