How do drafting chairs support the lower back?

Drafting chairs support the lower back through lumbar pads, contoured backrests, and tilt mechanisms that maintain appropriate posture. A lumbar pad presses against the inward curve of the lower spine to prevent slouching. The backrest height ensures support from the lumbar region through the upper back. The tilt tension resists excessive reclining that would arch the lower back. Without these features — as in a basic backless stool — lower back support is absent.
