A play-gymnastic apparatus (1) comprises a mat (2) having a multi-layer structure formed by a plurality of layers (21, 22, 23, 24) of flexible expanded synthetic foam, wherein the opposite sides of the mat are provided with respective layers (21, 24) of flexible expanded synthetic foam having a density higher than that of the innermost layers (22, 32). A series of holes (25) are formed in the mat, which holes are arranged according to an order fixed in advance. Moreover, the apparatus comprises one or more auxiliary shaped members (3) of flexible expanded foam, such auxiliary members being adapted to be mounted as a fixed joint in one or more different holes in order to obtain desired configurations of use of the play-gymnastic apparatus (1). |
