How do I adjust an office chair correctly?

Adjust in this order: (1) Seat height — feet flat on the floor. (2) Seat depth — 2"–4" space between front seat edge and back of knees. (3) Lumbar height — support in the inward curve of the lower back. (4) Backrest angle — 100°–110° recline. (5) Armrest height — elbows at 90°. (6) Tilt tension — moderate resistance.
