How do I adjust an office chair correctly?

Adjust in this order: (1) Seat height — feet flat on the floor, thighs parallel to floor. (2) Seat depth — 2"–4" space between front seat edge and back of knees. (3) Lumbar height — support sits in the inward curve of the lower back. (4) Backrest angle — 100°–110° recline. (5) Armrest height — elbows at 90° with forearms parallel to desk. (6) Tilt tension — moderate resistance from your normal seated position. At OfficeFurniture2go.com, we provide setup guides with every chair order — call 1-800-460-0858.
