An apparatus utilizing a flexible web construction, including a series of electrical heating resistance elements directed therethrough. The mat includes a ribbed upper surface overlying a ribbed bottom surface. The upper surface includes sloping side walls positioned medially about a central ridge to direct fluid downwardly from an upper surface of the mat. Hollow chambers are optionally formed throughout the mat longitudinally thereof overlying the electric coils to cushion the coils and simultaneously produce heat chambers for maintaining a constant temperature throughout the web construction. Further, fiber optic cables may be included in side chambers longitudinally coextensive with side edges of the web to illuminate boundary portions of the web for individuals during limited light conditions.
