ABSTRACT:
A floor mat is provided with a generally flat upper wall with a multitude of y-shaped ribs extending vertically downward from the upper wall to a floor surface, supporting the mat. Each of the y-shaped ribs has a solid central core with three legs which extend horizontally radially outward from the core. The distal end of each of the legs is bulbously enlarged. The ribs are spaced apart in a symmetrical pattern so that two sides of three adjacent ribs cooperatively define a generally cylindrical pocket. The pocket, while forming an enclosure, nevertheless had lateral openings at three equally spaced locations formed by the ends of each of two adjacent ribs being spaced slightly apart allowing for ingress and egress of air from the pocket. Located above the center of each pocket is a hollow dome formed in the upper wall.
