This chair looks great and is super comfy. My only complaint is that it is creaky when moving around in it. Some noise might go away once broken in. We shall see.
I picked up the grey bonded leather chair a few months ago and it has definitely made a difference in having to sit at a desk for hours at a time. The chair is comfortable and the rollers move freely. If you need added lumbar support I recommend placing a small pillow at the small of your back.
