Maintaining Posture Adjust your chair
Choose an adjustable office chair. Move the seat until both feet are flat on the floor, legs hip-width apart, knees over ankles, backs of thighs well supported. Adjust the back of the seat to support your lower back with shoulders balanced over hips, ears aligned with the shoulders. Position the monitor so that you face forward. Keep elbows at right angles to upper arms, shoulders relaxed.
