Pros: - Premium quality of all material (even the screws :) ) - Despite all the cons in my case, a value for money chair. - The idea of operating the chair with just 3 buttons and a side knob for the tilt tension is unique and extremely useful. - Hand rest angles are really good and the hand rest is extremely sturdy with just enough cushion. - Most of the parts are made of strong steel alloy. Cons: - The mesh is extremely rough and may cause rashes. But I think this depends on the weight of the person. - If your weight is close to the weight carrying capacity of the chair, you may feel the seat mesh going down a bit too much. - Hand rest can get sweaty and sticky. - Head rest can only move up or down. So, it doesn't support the upright position especially if you work on a laptop. - The back is divided into two parts so I thought that the angle between the two parts can be adjusted according to my back shape. But the two parts are fixed in the same place. So you may get very good lower back support but upper back support may be irritating. - The chair doesn't have an upright position. It is slightly tilted so you tend to lean back by default.
