  • the polymer foam has a higher compression hardness and higher restoring forces than the viscoelastic polymer foam in the first layer 1. As a result, forces can be absorbed that can not be cushioned or damped by the first textile surface element 2 and the layer with viscoelastic polymer 1 when running over the ground cover.
  • FIG. 4 shows another ground cover according to the invention.
  • a second layer 5 is arranged, and below layer 5, a third textile surface element 6 is arranged.
  • This second layer 5 comprises a polymer foam.
  • the polymer foam has a higher compression hardness and higher restoring forces than the viscoelastic polymer foam in the first layer 1.
  • the third textile surface element 6 comprises a fabric.
