Setting up your computer desk and chair
When you are setting up your computer desk and chair, make sure that the
desk is the appropriate height and the chair helps you maintain good posture.
■
Select a flat surface for your computer desk.
■
Adjust the height of the computer desk so your hands and arms are
positioned parallel to the floor when you use the keyboard and mouse. If
the desk is not adjustable or is too tall, consider using a keyboard drawer.
■
Use an adjustable chair that is comfortable, distributes your weight evenly,
and keeps your body relaxed.
■
Position your chair so the keyboard is at or slightly below the level of your
elbow. This position lets your shoulders relax while you type.
■
Adjust the chair height, adjust the forward tilt of the seat, or use a footrest
to distribute your weight evenly on the chair and relieve pressure on the
back of your thighs.
■
Adjust the back of the chair so it supports the lower curve of your spine.
You can use a pillow or cushion to provide extra back support.
Setting up your computer and computer
accessories
■
Set up your computer so the display is no higher than eye level, the display
controls are within reach, and the display is tilted to be perpendicular to
your line of sight.
■
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 display.
