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 medium-back, a high-back, a reclining seat, or a power elevating seat, refer to the following information.

separate manuals.
WARNING! If your power chair was configured by your authorized Pride Provider, 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! Remove the occupant from the power chair before making any adjustments.
You may need the following to make comfort adjustments:
