Getting Started
Selecting a place to work
Correct posture and positioning of the computer
Position your chair so that the keyboard is at or slightly lower 
than the level of your elbow. You should be able to type 
comfortably with your shoulders relaxed and your forearms 
parallel to the floor.
If you are using a conventional chair: 
Your knees should be slightly higher than your hips. If 
necessary, use a footrest to raise the level of your knees and 
ease the pressure on the back of your thighs.
Adjust the back of your chair so that it supports the lower 
curve of your spine. If necessary, use a cushion to provide 
extra back support. Lower-back-support cushions are 
available at many office supply stores.
Sit with your back straight so that your knees, hips, and 
elbows form approximately 90-degree angles when you work. 
Do not slump forward or lean back too far.
