Abstract: A floor mat construction of rubberized material including a base and feet of barbell-like configuration which extend integrally downwardly from the underside of the base for the support thereof in upwardly spaced relation on a supporting surface. A plurality of apertures the upper ends of which are of substantially hexagonal configuration, extend through the base to define a hexagonal honeycomb-like configuration in the upper portion thereof. The mat is lightweight but structurally efficient, the upper surfaces of the common walls between the hexagonal upper ends of the apertures providing durable scraping surfaces for a nonskid effect, and the feet firmly gripping the supporting surface therebeneath to resist creeping of the mat.
