The first thing we do with this modification is cut out most if not all of the foam in the driver's sitting area and that depends on if they want their position changed. We then reshape the remaining foam to give the sitting area a shape which helps disperse the rider's weight better. We then replace the foam removed with one layer of our memory foam that is designed specifically for sitting applications the rider's weight. We reshape the work with the previous reshaping of the original remaining foam to give the rider a very comfortable ride. The factory seat cover is re-used with this modification.
