[/caption]Posture:
The staircase position is the proper posture when working on a keyboard. Sit with your back straight, leaning slightly against the backrest at a 90° angle with the seat.
Your thighs and legs should form a 90° angle.
Your forearm should form an angle of approximately 90° with your arm.
Never bend your wrists. Repeated long periods of work in this position cause sharp pain in the wrist, also known as carpal tunnel syndrome.
Do not raise the top of the keyboard even if it comes with feet to do so. Raise the base of the keyboard instead.
Your neck should be straight. Do not have your head too far in front of the rest of your body.
