the upper arm and the lower arm, should all be maintained or slightly larger than ninety degrees.
Adjust the height of the display, tilt the head down slightly (as shown above); adjust the position of the keyboard so that the upper arm
and the arm are equal to or slightly larger than ninety degrees.
Adjust the height of the seat so that the thighs and calves, thighs and upper body are equal to or slightly larger than ninety degrees.
The waist is kept straight and close to the back of the chair. It is best to have a cushion support.
There should be approximately one fist space behind the front end of the seat and behind the leg; if the feet are not flat on the ground,
a foot pedal can be used.
