I wasn't sure about the mesh seat but it is very supportive and comfortable. I would recommend this chair to anyone who sits at a desk for long periods of time. The adjustable armrests are a bonus as they move up and down and back and forth. I'm not letting any of my co-workers borrow this one! HA!
Very disappointed in my chair. The one in the store seemed very supportive for the lower back. My chair does not offer this support and every time I sit in it I slide forward and sometimes almost fall completely out of the chair.
