    摘要： The present invention concerns a floor covering, such as a carpet, containing a first textile planar element and a first layer which is at least partially connected to the first textile planar element over their surfaces, wherein the first layer contains viscoelastic polymer foam. The floor covering according to the invention is characterized in that the first textile planar element has a modulus of elasticity of ≧0.5 N/mm2 to ≦2.5 N/mm2, that in the first layer 1 the viscoelastic polymer foam has a compression load deflection at 40% compression of ≧1 kPa to ≦10 kPa and that in the first layer the viscoelastic polymer foam has a hysteresis when determining the compression load deflection at 40% compression of ≧20% to ≦70%. The present invention also relates to a method of manufacturing a floor covering.
