At less than 6 months since purchasing the hydrolics failed and the seat sinks to lowest level as soon as I sit on it. There is no adjustment for the hydrolics. Worst chair I ever owned.
Will get back to you when the chair is out of the box and in use—2-3 weeks. Can say I chose it because I am quite petite and the two on the floor were set up for a taller person and one my size. Good marketing!
This is the best desk chair I've had in a very long time. It is lightweight and has excellent lumbar support. It's not so big that it gets in the way of my desk's keyboard tray. I just love it!
