The present disclosure relates to an anti-fatigue flooring article having inherent properties of electrostatic dissipation. Further, this disclosure relates to flooring article having at least two layers, wherein a first layer (comprised of dense rubber) is calendered to a second layer (comprised of foam rubber). Each layer has a different electrical conductivity, thereby creating a mat having an appropriate range of conductivity when combined. The present flooring article may also include a layer of static dissipating scrim, a grounding means, and/or a colored marking.
