the backrest (Fig. 3). Slide the shroud toward the center of the seat. Place the back-
rest bottom into the seat slot located at the rear of the seat. Match up the holes in the

STOOL ADJUSTMENTS
Back Height
Grasp the lower edge of the backrest and lift it as far as it will go to disengage the
height locking mechanism (Fig.7). Next, lower the backrest as far as it will go to reset
the height locking mechanism. Finally, lift the backrest to the height desired.
For maximum comfort, the backrest should be positioned firmly against the lumbar
region of your back. The backrest has eight heights to which it can be set.
Body Support Height (if equipped)
The body support has a lock collar and knob which may be placed in any one of three positions (Fig. 8, 9, and 10). To
adjust the lock collar and knob into a new position:
1. Loosen the body support knob until the lock collar moves freely on the swing arm. Do not completely remove the
knob from the lock collar.
2. Reposition the lock collar and knob to the new position, and tighten the knob just enough to hold the lock collar in
place.
3. Install the body support post into the swingarm with the channel of the post aligned with the threaded end of the
knob.
4. Tighten the knob to secure the body support.
Seat Height
To adjust the seat height downward, sit on the chair and lift the lever under the seat
side edge (Fig. 6). To raise the seat height, remove your weight from the seat and lift
the lever under the seat side edge. Release the lever at the desired seat height.
For maximum comfort, your chair seat should be adjusted so that your hands rest
comfortably on your work surface. Your feet should be flat on the floor with the inside
angle of the knee joint being slightly more than 90 degrees, and you should feel no
pressure underneath your thighs. Fig. 6
