1. Seat Height
When sitting your hips should be
slightly higher than your knees in
order to promote good posture.
When your shoulders are relaxed
and elbows are at right angles,
your forearms should be just
above the surface of the desktop,
parallel to the floor.
To alter the seat height lift the
lever at the front right side as
shown and release when at
desired height.
When perching you may also find
an extended seat position
beneficial (see: seat slide)
LIFT

2. Automatic Brake
When the seat is raised above
650mm, an automatic brake
engages at the moment a users
weight is applied.
This has the effect of stabilising
the chair, making it safe to work
in an elevated or perching
position.
An optional footring is
available for users wishing
to work at a raised
level.

3. Seat Depth
Your bottom should be at the
back of the seat with roughly
three fingers’ gap between the
front of the seat and the back of
your knees.
This will ensure adequate thigh
support without obstructing leg
movement or lower leg
circulation.
To alter the depth, lift the lever at
the rear left side as shown and
slide seat to desired position.
Release lever to lock in position.
LIFT

TURN (Please note the knob rotates in both
directions and alternates the
lock/unlock function).
4. Backrest Angle Adjustment
To fix the back rest angle, rotate the
knob by one click to unlock then
move the backrest to your desired
angle.
You can lock the back position by
rotating the knob one more click.
If you require the chair to operate
in Free-Float mode leave the back
rest unlocked (in the first position).
The tension is automatically set by
the weight of the user.
For the very best effect when
sitting, use together with the seat
tilt also in Free-Float mode. (See: seat
pivot)

5. Back Height
Lock the back rest in a vertical
position. When seated, grasp
the sides of the backrest and
raise one click at a time until
comfortable.
The Zenki Sit Stand features a
7- position ratchet system.
To reposition the back, lift fully
to the top, lower to the bottom
to re-engage ratchet and raise
again to the desired height.
The lumbar curve of the back
rest should fit into the small of
your back to help maintain the
natural ‘S’ shape of the spine.
PULL UP

6. Seat Pivot (& Free Float)
The seat is locked/unlocked by
rotating the knob with alternating
clicks - as with the back rest (step 3).
Having both the seat and back rest
unlocked together will provide the
full Free-Float experience.
The chair reacts to your centre of
gravity and helps promote stress-
free neutral posture combined
with continuous movement.
If you prefer you may lock the
seat when the desired angle is
achieved.
(Please note the knob rotates in both
directions and alternates the
lock/unlock function).
Seat only unlocked
Seat & back rest unlocked together
TURN

7. Body Weight Tension
The resistance of the mechanism
in the Free-Float mode is
automatically set by the weight of
the user.
The resistance can be increased
to give a more controlled feel if
desired.
The tension adjustment handle is
located at the front right side of
the seat.
Twist clockwise to increase
tension and anti-clockwise to
reduce.
TURN

+/-

8. Lumbar Support
You can adjust the level of
support for the lumbar area of
the spine by pumping the inflator
bulb located on the outer back
rest.
The air cell helps support your
natural spinal curve.
If necessary reposition the
backrest height to maximise
comfort.
To deflate the air cell press the
valve button on the neck of the
the pump bulb. To lock twist the
button on the neck of the valve.
PRESS

9. Multiway Armrests (Optional)
The armrests should touch the
underside of your forearms when
your shoulders are relaxed and
elbows are at right angles.
This will avoid stress in the neck,
shoulders and upper limbs.
To adjust the height, press the
trigger on the underside of the arm.
For width adjustment loosen the
handle, slide arm to the desired
width then re-tighten the handle to
set.
The arm pads are free float and can
be moved in/out to/fro and also
turned inwards (see graphic)
