I bought this chair wanting something sleek and all black without a million plastic levers. This thing fits that bill really well and keeps you back nice and cool and supported. My only complaint with this chair is the lumbar support. First off you really only get one position because it won't stay in any of the other positions. As soon as you raise it it sinks back down to the bottom. Second it is hard plastic that doesn't have much give. AKA it isn't at all forgiving. I am 5' 11" and thankfully the lumbar support works for me in the lowest setting but if you are taller than that I would probably look elsewhere for a chair with more robust lumbar adjustments
This chair is easy to assemble it takes about 15 minutes. The chair is very comfortable and easy yo adjust the height and how much the back reclines. Much more comfortable than simular chairs that are more expensive.
