We purchased this Quantum Edge for my Dad who was 6'3".  Since he was a framer it is John Deere Green.  Unfortunately just a few months after the chair was fitted to him he passed.  Shortly there after my mother fell ill so we had the chair retro fitted to her, 5'2".  It adjusted to fit either of them perfectly. Then as providence would have it my mother also passed just a few months after the chair was fitted for her.  We have continued to move the chair regularly in order to keep the battery functional. The reason we purchase this particular chair is that it was an all terrain chair and we were able to occasionally take my dad our to his hanger to look as his airplanes was well as some of his farm equipment.  It was a real blessing for him to be able to go outside and not try to push him in a chair that could get stuck. (We were never in the mud, but on a paved driveway as well as a rock hard surface road.)

I would be able to provide a video if wanted.  We also have a Van that was fitted with a wheelchair locking system that is available for sale as well as a tram lift.  I will be happy to answer any questions you might have.
