COMFORT ADJUSTMENTS
After becoming familiar with your power chair’s operation, you may find the need to make some adjustments to increase your
comfort. These adjustments include seat height and angle, armrest angle, foot platform height and angle, and controller
position. If your power chair is equipped with a Specialty Seat or a Synergy Seat, refer to the information provided in separate
manuals. If your power chair is equipped with a contoured seat, refer to the following information.
WARNING! If your power chair was configured by your Quantum Rehab Specialist, please consult
your healthcare professional before changing the seat position or making any other adjustment.
Some adjustments may degrade your power chair’s performance and safety by changing its center of
gravity.
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! Prevent injury. Remove the occupant from the power chair before making any
adjustments/repairs.
