I had previously bought a chair for my wife's 'command center' home office but she later said she wanted one with a mesh vice cushion bottom. I set this one up today and she says the difference is obvious between 'stupid designer' of her old chair and 'not stupid designer' of this chair. She has had episodic lumbar issues since a car accident, and she likes the back support and the design of the seat and how they work together. The directions are easy to follow and set up is easy.
