The Ultra Dome fits the budget of the gym owner as well as the gymnast who desires a home use apparatus. The dome is made of durable, molded polyethylene. The padded top easily detaches for floor circle work. The dome can be stacked onto a second base for an increased height of 5 inches. The Ultra Dome has the advantage of excellent stability on a spring floor surface and plural use as a small spotting block or preschool "shape". Low cost, simple storability and great portability can provide multiple training stations and better lesson environments. UPS shippable
