This Quantum Q6 Edge is the Mercedes of Power Chairs loaded with top of the line adjustable components including: * Swing-away Jack Mount * Power Seat Elevator * The best seat cushion and headrest * Power Recline * 6 Key joystick which gives lots of speed options * a large charging capacity (all day travel) The chair listed for $20,000 but was sold as a demo. Dad used it for a few weeks. He really liked that the chair could pivot on the spot, vs inching, meaning having to back up and then go ahead until you are turned around. The Swing away joystick allowed Dad could sit at any table comfortably. Dad liked the power seat elevator assistance in getting out of the chair.
