This is a fantastic chair!  I am a bigger girl that is only 5'6" that has back and hip issues from a car wreck.  This chair is extremely comfortable!  The sloping seat feels fantastic with my legs, they don't feel stressed like they did in my old chair. The lumbar is a little high for me, but I expected that in a big and tall chair.  I sit in front of my computer at work 90% of the day, so I am VERY happy with my purchase.
