Despite its seemingly simple structure, the Sport Disk will provide kids with hours of entertainment. It consists of a round pedestal mounted on a big commercial-grade swing. Children can stand on top of the pedestal and try to maintain their balance as they tilt back and forth. It can be thought of as a spring rider pony, but for school-aged kids. The pedestal has a bumpy high-traction surface to help kids stay on it. The strong spring is built to stay upright and unbent, even after years of bouncing and tilting. Proper safety surfacing is, of course, needed in the area around the Sport Disk.
