| The order in which you follow the advice in the previous sections depends on the adjustability of your work surface. |
|
• |
If your work surface height adjusts, then systematically adjust yourself and your computer "from the ground up." |
|
• |
If you have a fixed desk or table, systematically adjust yourself and your computer "from the top down." |
From the ground up
- Seat height: you should be able to plant your feet firmly on the floor.
- Chair back angles and lower back support: your back should be well supported.
- Keyboard height: home row should be near your elbow height.
- Keyboard slope: wrists should be in a comfortable, neutral position.
- Pointing device: should be placed to the immediate left or right of your keyboard.
- Optional forearm support: shoulders should be relaxed and forearms evenly supported.
- Monitor distance, height, and angle: should allow your head to be balanced comfortably over your shoulders.
- Document holder, phone, and reference materials: frequently used items should be within easy reach.
