Chapter 2: Setting Up and Getting Started
8
• 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 touchpad. If the desk is not
adjustable or is too tall, consider using an
adjustable chair to control your arm’s
height above the keyboard.
• 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.
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 far back.
Sit with your back straight so your knees,
hips, and elbows form right angles when
you work.
• Take breaks to stand and stretch your
legs.
• Avoid twisting your torso or neck.
