Hog Heaven Fashion mats feature the same excellent anti-fatigue qualities of a standard Hog Heaven mat, but with an attractive, fabric top. All Hog Heaven mats feature a durable, long-lasting memory foam cushion made from a blend of nitrile rubber and PVC (vinyl). The attractive fabric surface of the Hog Heaven Fashion mat is molded to the cushion (not glued) so it will not separate. Itâs made from PET fabric, an type of polyester made from post-consumer recycled plastic drink bottles. The diamond pattern surface is both attractive and stain resistant.
