Seat Height Adjustment*
1
Seat height adjustment lets you adjust the chair to properly
position your body at the worksurface and maintain proper blood
flow in your legs. Seat height should be adjusted to allow your
legs to maintain a
90-degree angle to the floor or footrest. (1)Pull up on the lever
and raise your body out of the chair to increase seat height. (2)
Stay in the chair and pull up on the lever to decrease seat height.
Seat height adjusts 120 mm from 420 mm to 540 mm on
standard models and 130 mm from 400 mm to 530 mm on
Fern Type A.
*The indicated dimensions are determined while chair supports a load of 64 kg.
2 Seat Depth Adjustment
Seat depth adjustment moves the seat pad to accommodate
different leg lengths. It helps you sit back far enough in the chair
to use the backrest without creating pressure behind the knees.
With a full 80 mm of seat depth you have lots of room to adjust,
so blood flow to your legs isn't restricted and you stay alert.
(1) Pull up and slide the seat forward to lengthen, or backward to
shorten. A minimum of two fingers should fit between the back
of your calf and the front of the seat.

3-point synchro mechanism
A comfortable, relaxed posture is facilitated by the recline
feature,which allows for the opening of the users' chest cavity,
providing a good airflow to promote alertness. Aligning the
location of the mechanism's pivots with the pivot points of
the body—namely, the hip, knee, and ankle—ensures optimal
ergonomic support.This alignment facilitates the maintenance of
user posture, ensuring that the back maintains contact with the
chair's backrest while reclining.
4 Tilt Tension Control
Regulates the amount of resistance felt when leaning back in the
chair and the effort required to recline the chair backwards.
(1) Turn the crank forward (clockwise) to tighten the tension and
backward (counter-clockwise) to loosen the tension.
Once the tension has reached its maximum in either direction, do
not force the crank further.
The crank can be pulled outward for easier operation; please
push the crank back inward after operation.
