Scientific evidence now confirms road vibration and related body motion on vehicle seats generate micro-electrical charges on the body.  The Earthing® Auto Seat Pad neutralizes these charges on the body.  Made of a strong and conductive carbonized rubber, the grounder pad measures 10" x 10".  The pad easily connects to the metal seat of your car or truck with a small alligator clip to dispel excess charges that have accumulated on your body.
