Basically, it is my opinion this is a very high-quality for this low price chair. The lumbar spine is excellently supported and also the tilt and height-adjustable headrest is always a great thing. However, one should pay attention to the specified reclining / or head restraint height on the purchase. This chair is really only suitable for very small people. Mir (1.73) extends the headrest is fully extended state just to the shoulders, is not really a headrest: /. Other shortcomings are the seat, which is not ergonomic and the fact that you can, if you want to return the chair must bear the shipping costs for the huge box that come loose at the purchase price, even!
