A floor material of the playground improving the elasticity is provided that drainage is easy and the impact absorption is well. A floor material of the playground improving the elasticity comprises several coil springs(140) which is connected to the lattice frame so that the movement is prevented, a panel combined in the upper end of the coil spring, an edge block(300) which is combined in order to be mounted on the side border, a concave-convex region prepared in the panel in order to form waterway, and a plate(150). |
