Abstract

A mat base plate for use with a shrinkable mat is shown including an upstanding rim extending around a floor of the mat base plate. The rim has a plateau surface at the top thereof, an outer wall and a slope extending from said plateau, continuously to the bottom of the mat-receiving basin that is constituted by the rim and floor of the mat base plate. In the fourth embodiment, the rim is semi-cylindrical or at least convexly arcuate in cross-sectional shape, and has a rough surface having the appearance of a plurality of wave-like convexes and concaves.
