OPERATING INSTRUCTIONS

1. To Adjust Seat Height:

While seated, reach under the right side of the
chair to find the handle. Lift the handle and raise
your body up slightly to allow the chair to rise to
the desired height. To lower the seat, lift the
handle while applying more weight downward on
the seat. The chair will descend until the handle is
released or the chair reaches the bottom position.

2. To Operate Tilt Lockout

While seated, reach under the left side of the chair
to find the handle. Push down the handle and lean
back to allow the chair to tilt backwards. To lock the
chair in the upright or vertical position, sit upright
and pull the handle to the level position.

3. To Adjust Tension on The Tilt:

Reach under the front center of the chair, grasp the
round knob and turn counter- clockwise to make
the tilt mechanism firmer (stiffer). To make the tilt
mechanism less firm, twist the knob clockwise until
the desired resistance is found.

4. About the Back in Motion:

While seated, the seat and lumbar are fixed
together on a tilting axis that allows you to rotate
your pelvis while flexing the muscles of the core. It
allows you to articulate the spine and perform
pelvic tilt exercise. This increased both strength &
circulation while reducing pain.

Please check to ensure that you have received all the parts for the assembly of this chair. If you find any
missing or damaged parts, do not return to the store. Please call toll free at 1-855-372-2315 for assistance.
Service hours are: Pacific Time: 6:00 am-5:00 pm Monday – Friday. Please note that a receipt is required for
all warranty replacements. This chair has been tested and approved for normal use which is defined as a
standard work week of forty hours by a person weighing less than 250lbs (113kg).

* Note:
Before placing your full weight onto the chair, ensure
you are fully positioned against the back cushion and
not sitting on the front edge of the seat, as the front
edge is designed to tilt forward. This may result in a fall.
