This is a standing system for paraplegics or quads. If you cannot stand or sit in a wheelchair all day this is for you. This machine brings you to a standing position directly from your wheelchair with no transfers. Standing for a few minutes a day helps maintain bone density, increase circulation, and gets you up and out of that chair! Retail price is over $2000. This is used but in great condition. You can check out more info from the manufactures web site listed below. Located in San Diego you must provide transportation. Call Rob 619-248-3343. Asking $999 or best offer!
