I'm the Heron ergonomic office chair, I come standard with a black mesh ratchet back that you can move up and down while sitting. My back follows you while you move, supporting your lower lumbar as you move around your office desk and workstation. I have a 3 lever mechanism allowing for seat tilt and back tilt adjustment with a ratchet back height adjustment. I come in a number of colour options making me match most environments.
