The Back-Saver is simple to operate and does not require any manual lifting. Just fold the chair up and roll the chair onto the platform. Turn the key to the ON position and depress the rocker switch to the UP position. Unloading the chair is just as simple and trouble-free. It is rated to handle most folding wheelchairs with 22-inch or larger rear wheels, weighing 70 lbs or less. In addition, the Back-Saver meets state and federal D.O.T. regulations for license plate illumination and visibility. The Back-Saver also includes an extra brake light for security and peace of mind.
