Generally, the chair provides good lumbar support, but so much so that sometimes I feel like I am going to fall right out of it, even when scooted back the most deep position available. The fabric on the seat is incredible sticky and makes you sweat. I am not an overly large person, nor do I normally perspire while just sitting and working, which makes me think... it's not me. Will be returning this chair in favor of something else. Too bad.
