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. If your
power chair is equipped with a specialty seat, refer to the information provided in separate manuals. If your power chair is
equipped with a medium-back, a high-back, or a reclining 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.
