Computer Basics
Setting up your computer table and chair
When you are setting up your computer table and chair, make sure that you
use a computer table that is the appropriate height and use a chair that helps
you maintain good posture, distributes your weight evenly, and keeps your
body relaxed.
■
Select a flat surface for your computer table.
■
Adjust the height of the computer table so that your hands and arms are
positioned parallel to the floor when you use the keyboard and mouse.
■
Position your chair so that the keyboard is at or slightly below the level
of your elbow, letting your shoulders relax while you type comfortably.
■
Adjust the height of your chair so that your knees are slightly higher than
your hips. You can use a foot rest to adjust the height of your knees and
remove the pressure on the back of your thighs.
■
Adjust the back of the chair so that it supports the lower curve of your
spine. You can also use a pillow or cushion to provide extra back support.
Setting up your computer and computer accessories
■
Set up the monitor so that the top is no higher than eye level.
■
Place your keyboard and mouse at a comfortable distance. You should
be able to reach them without stretching.
■
Set paper holders at the same height and distance as the computer
monitor.
Sitting at your computer
■
Avoid bending, arching, or angling your wrists. Make sure that they are
in a relaxed position when you type.
■
Do not slouch forward or lean back too far.
■
Sit with your back straight so that your knees, hips, and elbows form
approximately 90 degree angles when you work.
■
Avoid twisting your torso or neck.
