For the price compared to any high-end ergonomic chair it is worth every dollar. The seat cushion is very comfortable as well as the back rest and fabric padded arm rest. The adjustable lumbar support is really there for decoration since it just wobbles and is not so sturdy, I really don't even feel it touching my back but the way the mesh already has a curvature of the lumbar region I really can't complain it does the job. Has a bit less lumbar support for my liking but with a chair this price you really can't go wrong. 4 stars because I can't really feel the adjustable lumbar support. Overall good chair!
