The invention relates to a device (1) for a tumbling floor, which comprises an underbody having springy elements (4) resting thereon, such as glass fibre tubes attached to end portions. According to the invention, the underbody (3) is formed of reinforced foam elements and which reinforcement (9) is arranged to decrease the compression of the foam elements. Thereby, it is allowed to obtain a light but still strong tumbling floor, which does not collapse upon large load. |
