Organizing Your Adjustments
The order in which you follow the advice in the proceeding chapters 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
1.
Seat height: you should be able to plant your feet firmly on the floor.
2.
Chair back angles and lower back support: your back should be well supported.
3.
Keyboard height: home row should be near your elbow height.
4.
Keyboard slope: wrists should be straight.
5.
Pointing device: should be placed to the immediate left or right of your
keyboard.
6.
Optional forearm supports: shoulder should not be elevated or dropped.
7.
Monitor distance, height, and angle: should allow your head to be balanced
comfortably over your shoulders.
8.
Document holder, phone, and reference materials: frequently used items should
be within easy reach.
From the Top Down
1.
Seat height: elbow height should be near your keyboard’s home row.
2.
Footrest, if you need one.
3.
Follow steps 2 through 8 above.

Be Inventive
Adjustable furniture designed for computer use may not always be available.
However, you can use towels, pillows, blankets, and books in many ways, such as
to:
• Raise the height of your chair.
• Create a footrest.
• Support your back.
• Elevate the keyboard or display.
• Provide arm supports if you are working on a sofa or bed.
• Provide padding wherever needed.
