The present invention is a floor mat made from a rubber composite, the composite having a foam rubber core positioned between dense rubber layers. Protrusions or cleats, which are produced during the vulcanization process, extend outwardly from the lower surface of the mat. The present mat offers mat users desirable anti-fatigue characteristics that are achieved by (a) a combination of dense rubber and foam rubber layers and (b) the spaced positioning of a plurality of cleats over one surface of the mat. Such a mat is anticipated to be useful in service environments, such as hair styling salons, retail outlets, or restaurant kitchens, for example.
