User Instructions
The mechanism
We use the 5-way adjustable, heavy-duty mechanism for the Uni Bespoke chairs because it has the added advantage
that both the seat and back tilts can be locked independently in any position and has been rated up to 150kgs.
It comes with seat slide as standard as well as a ratchet backrest height mechanism and seat tilt tension controller.

1. Seat Slide Lever
On the left hand side of the seat is the lever to slide the seat
forwards and backwards and allows the seat to be adjusted
by up to 50mm
2. The Seat Height Adjustment Lever
Controls the gas lift for the seat height adjustment. Contrary to
popular belief, the first consideration is to ensure your elbows/
forearms are at the correct height. Raise or lower your seat so
your desk height is at elbow height. If you can't reach the floor
after this adjustment, then you need a footrest. The final seat
height will depend on the final seat angle you set.
3. Seat Posture Lever
Controls the seat tilt. When you lift this lever, the seat is free to
move. Push the lever down to lock. The best position is tilting
forward slightly as a tilting forward angle means your hips should
be a little higher than your knees; i.e. your thighs should slope
downwards as much as you find comfortable.
This promotes better posture. Also, the further back you sit into
your chair, the easier you will find it to control the seat tilt angle.
If you find the seat tilt too difficult to control, then you will need
to slacken the spring by turning knob (5) anti clockwise. If you
find it too easy to tilt, you need to tighten the knob (5) by
turning clockwise.
4. The Back Posture Lever
Controls the back tilt. Lift the lever to unlock. Push the
lever down to lock. This can be locked in any position. It is
recommended to set the backrest in an upright position to
ensure your spine is as straight as possible.
The backrest height works using an easy lift ratchet mechanism.
To raise the backrest simply lift the back with both hands one click
at a time. There are 8 clicks (locks) before you reach the top of the
ratchet and it will disengage. Drop the back down to the bottom
to re-engage.
5. Seat Tilt Tension Control
The tension of the tilt is controlled by turning the handle clockwise
(to increase) or anti clockwise (to decrease) the internal spring.
