IT IS TRUE! The rubberized mats will discolor hardwood, laminate, vinyl, and even carpet.. My carpet cleaning company asked me what happened to my carpet after I had a rubber-backed throw rug sitting by the fireplace so that no sparks came out onto the carpet. It was yellowed in the area of that little rug.
