The present invention, in addition to achieving a cost advantage, also produces a covering material that provides better sitting conditions, equivalent to the foam backed covering materials with respect to physical textile values yet being easier to recycle and. In addition, recycled textile products can be worked into the covering material of the present invention as reprocessed fibers without losing any advantage.
