What is the foot ring on a drafting stool for?

The foot ring is a chrome ring around the base column that provides a footrest when the user is seated at elevated height — without it, legs dangle unsupported and cause pressure under the thighs within 15–20 minutes. It should be height-adjustable on quality models so it can be set 12"–16" below the seat.
