Abstract: A floor (1) with built-in resilience which makes it suitable for use in different sports both indoors and outdoors. The resilient floor is built up of mutually parallel studs (3) with recesses extending in the transverse direction. In the recesses, fillets (5) are arranged which extend beyond the upper side of the studs (3) and support surface planks (6). The recesses which are mirror-symmetrically arranged about a center axis transversely of the respective stud (3) have at least one inclined wall, the walls of the recesses intended for the same fillet (5) and positioned in adjoining studs (3) being inclined in the opposite direction. The fillets (5) are clamped in a wave-like manner in the associated recesses, in that they engage the inclined walls.
