ORANGEBOX ARA Quick Start Manual

1a. Adjustable arms
Each arm pad is height adjustable by pressing the button on the outside of the armrest and sliding up and
down into the desired position. If possible, your forearms should be supported at 90° to your upper arms with
your shoulders relaxed.
1b. Multi-adjustable arms
1
Height: Arm pad is height adjustable by pressing the button on the outside of the armrest and sliding up or
down into the desired position. If possible, your forearms should be supported at 90° to your upper arms with
your shoulders relaxed.
Rotation: Slide the control on the underside of the front of the arm-pad forward and rotate the pad to the
desired position. The soft touch pad can be rotated 180° rearward to allow you to work closer to your desk
or 30° inward to provide wrist support whilst typing. The arm-pad will automatically lock in the forward
position for additional safety.
2. Multi-adjustable lumbar
2
Ara's adaptive elastomer membrane has been designed to flex, this accommodates different shapes and sizes
of user but supports your back in a posturally correct 'S' shape. Because the back adapts to fit the user, Ara
doesn't need a height adjustable back, but the adjustable lumbar control can be used to fine tune
seating comfort. To fine tune lumbar height, reach round with both hands to grip the lumbar pad and pull up
or down to a position that suits. To fine tune lumbar depth, rotate the paddle in the centre of the vertebra,
clockwise to increase support from the pad and anti-clockwise to decrease the support from the pad.

3. Seat height control
Lift the paddle on the right hand side of the seat to raise and lower seat height. The seat height is locked when
the lever is released. It should be set so your feet are comfortably flat on the floor and if possible, your thighs
should be at 90° to your back (or slightly more) to help keep your pelvis upright and your spine aligned in a
natural 'S' shape.
4. Seat slide control
The seat slide control is situated on the right hand side of the seat, toward the front of the chair. It is adjusted
4
back or forward by pressing the button in whilst sliding the seat into the desired position. If possible, there
should be at least two fingers gap between the front of the seat and the back of your knees. This will ensure
adequate thigh support but without obstructing leg movement and lower leg circulation.
5. Back lock control
Lift the paddle on the left hand side of the seat to unlock the recline of the chair back and gently lean back to
recline. The mechanism has an anti-kick safety feature which means that adjusting the chair back to be more
upright also needs you to put a small amount of rearward pressure on the back first. Press the paddle down
5
again to lock the chair back in the desired position. For healthier sitting, keep the chair unlocked as much as
possible as this will encourage you to move more, which is better for you.
6. Body weight control
The recline resistance when the chair back is unlocked can be adjusted to suit your body weight by turning
the knob on the right hand side of the seat. Turn clockwise to increase resistance and anti-clockwise to
decrease resistance. The 'tension' should be set so that you are able to recline gently in a controlled manner
but without having to push uncomfortably hard.
