My physio suggested that a seat should measure ~3/4 the length of your hip to knee, and the back should be ~ the same as the distance between the base of your spine and start of your neck.
With your feet flat on the floor, your thighs should be ~parallel to the floor
HSE has guidance for chair & desk heights (their monitor height guidance is outdated though)
That being said, I don't rate herman miller - too much form over function, particularly at the premium they charge.
