I bought this on sale and I'm still not sure if it was worth it. The lumbar is nice as is the thickness of the seat but it isn't amazingly comfortable. Just more comfortable than your average economy computer chair. I still find myself adding my seat cusion for extra booty support. I'm 5'4" and I like the height; at its tallest which works for my tallish desk my feet just touch the ground. I put a stool under my feet so that I am set up for good posture. The chair goes back down nicely to fit under the desk. Easy to assemble looks nice easy to roll around.
