COMFORT ADJUSTMENTS
After becoming familiar with your power chair’s operation, you may find the need to make some adjustments to
increase your comfort, such as seat height and angle, armrest width, armrest angle and height, foot platform height
and angle, and controller position.
NOTE: If your power chair is equipped with a Specialty Seat, Synergy Seat, or TRU-Balance Power
Positioning System, refer to the information provided in separate manuals.
WARNING! The center of gravity of your power chair was factory set to a position that meets the
needs of the demographic majority of users. Your Quantum Rehab Provider has evaluated your
power chair and made any necessary adjustments to suit your specific requirements. Do not
change your seating configuration without first contacting Pride Mobility Products or your
Quantum Rehab Provider.
WARNING! Some power chair components are heavy. You may need assistance to lift or carry
them. Please refer to the specifications table for specific component weights before you
disassemble the power chair.
WARNING! Remove the occupant from the power chair before making any adjustments.

seat posts. See figure 15.
