The coaster permits air to circulate through the multiple cavities of the mesh to accomplish the evaporation of moisture and surface non-adherence and to allow any remaining residue to be easily absorbed by the absorbent bottom layer, which is extended in such a manner as to provide further ventilation by virtue of stand-off features or feet affixed on the base or bottom of the coaster.
