What's the best way to sit?

Sit in chairs with straight backs or low-back support. Keep your knees a little higher than your hips. Adjust the seat or use a low stool to prop your feet on. Turn by moving your whole body rather than by twisting at your waist.

When driving, sit straight and move the seat forward. This helps you not lean forward to reach the controls. You may want to put a small pillow or rolled towel behind your lower back if you must drive or sit for a long time.
