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 angle, 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 Position-
ing System, refer to the seat adjustment information contained in separate manuals. If your power chair is
equipped with a medium-back, a high-back, a reclining seat, or a power elevating seat, refer to the following
information.
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 16.

posts to the power base. See figure 16.
