The Quantum edge 2.0 power wheelchair is in excellent condition. It was used by my wife since November of 2017. The reason for selling the wheelchair is my wife passed away in July of this year. The chair does everything, the seat & back tilt together, the back tilts alone, the chair also has an elevator were the chair rises 8 inches to reach cupboards and other high places, my wife loved this capability. It has the ROHO seat cushion, the controller was replaced in March of this year. The chair comes with the owners manual, the pump for the ROHO seat cushion and the itemized list of all the parts & cost. The chair is in excellent condition and whoever buys it will love it, just like my wife loved it. The Quantum wheelchair is a top of the line wheelchair also the elevator feature on this chair is worth buying it, my wife loved to cook and with this feature she had no problem reaching anything she needed in the kitchen or even when she went shopping at the store, she could reach the products on the upper shelves. Its a great chair and would make some ones life much easier.
