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.
