your comfort, such as seat height and angle, armrest width, armrest angle and height, foot platform height and angle, and

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 adjustment that
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.
