Correct seating posture is an essential ingredient to preventing spinal injury and fatigue.

The basic features of a good chair are :

- height adjustable
- pelvic tilt on seat
- lumbar support

• Adjust the height of your chair such that your knees are level or just below hip height and that your feet are flat on the floor.
• If your seat has a pelvic tilt, this should be set to a slight forward incline to promote a natural inward lower back curve.
• Move the lumbar support so that it fits snuggly into the curve of your lower back. This will help to prevent lumbar strain and helps to maintain a straight spine and neck whilst seated.
• Never sit with your legs crossed! Crossing at the ankles is a preferable alternative.
