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 Synergy Seat or TRU-Balance Power Positioning System, 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 at your authorized provider/specialist, please consult
your healthcare professional before changing the seat position or making any other adjustment.
Some adjustments may degrade power chair performance and safety by changing the 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! Remove the occupant from the power chair before making any adjustments.
