•• Do not use the computer while you are lying down, but only while you are sitting down.

•• Do not use the computer on your lap. If the computer temperature increases, there is a danger of burning yourself.

•• Work while keeping your waist straight.

•• Use a chair with a comfortable back.

•• Keep the center of your leg weight not on the chair but on your feet when you are sitting on a chair.
