The tumbling mat Speedy 1500 is a tumbling mat. It is highly elastic and consists of multi layer double plywood panels with specially aligned and arranged damping elements. Exceptionally high spring forces are attached at the diagonal mat for practical floor exercises. This spring force and the damping are aligned with each other to reduce the peak forces. Existing floor gymnastics mats can be secured with the cover. The tumbling mat is based on a floor exercise mat. The width of the mat is 1.5m.
