Seat Tilt: Pull the lever and add or reduce
weight on the front area of the seat cushion to
move it into one of three positions. Release the
lever to lock the seat into position.
The tilt of the seat, along with the tilt of the
backrest and the contour of the seat cushion,
affects the amount of pressure placed on the
underside of the thighs and the back.
9. Armrest Tilt: To adjust the armrest angle, tilt the
armrest to the highest position, then down to the
lowest position, then to the desired position.
The armrest should be at an angle where the
elbows lay lightly on it; this helps to relax the
muscles in the shoulder and neck.
