How do I properly adjust the lumbar support on a drafting chair?

Sit fully back in the chair and locate the natural inward curve of your lower spine (lumbar region), typically 4"–6" above the seat. Adjust the lumbar pad height so it presses lightly into that curve — not into the mid-back or buttocks. If depth is adjustable, set it so you feel gentle support without being pushed forward. If you feel pressure only when you first sit but not when working, the lumbar is correctly positioned. OfficeFurniture2go.com includes ergonomic setup tips with all chair orders — call 1-800-460-0858.
