Head position:
Keep your head and neck in a comfortable and neutral (vertical, or upright) position.
Chair:
Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to
best suit your desired posture.
Arm and hand position:
If available, use chair arm rests or an area on your working surface to provide
weight support for your arms. Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal)
position. Type with a soft touch without pounding the keys.
Leg position:
Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.
What if you are traveling?
It might not be possible to observe the best ergonomic practices when you are using your computer while on
the move or in a casual setting. Regardless of the setting, try to observe as many of the tips as possible. Sitting
properly and using adequate lighting, for example, will help you maintain desirable levels of comfort and
performance.
Questions about vision?
The visual display screens of Lenovo notebook computers are designed to meet the highest standards and to
provide you with clear, crisp images and large, bright displays that are easy to see, yet easy on the eyes. Of
course, any concentrated and sustained visual activity can be tiring. If you have questions on eye fatigue or
visual discomfort, consult a vision care specialist for advice.
