What a difference my new chair has made! The lumbar supports makes a huge difference and the mesh seat is so much cooler than my prior cushioned chair.
The edge of the seat hurts my legs. Like the mesh is sticking out. I also wish the seat front was adjustable. For the money should have more adjustability.
The back is too high (I'm 5' 5") and there is no way to adjust so the headrest just pushes the top of my head forward. Some of the pre-drilled screw holes did not align and had to be "shaved" with a drill bit to put it together. Otherwise it's fine.
