What is the best drafting chair for prolonged sitting?

For prolonged sitting (4+ hours per day), choose a drafting chair with a contoured foam seat (3"–4" thick), an adjustable lumbar support that targets the L2–L5 vertebral region, a seat depth adjustment to accommodate different leg lengths, and a tension-adjustable tilt mechanism. Mesh back models provide better air circulation for extended use.
