Abstract
A flexible matting for use at an entrance porch, corridor, veranda, pool-side, interior floor of automobiles, etc. This matting consists of a base on which tread bars and rows of ridges bearing piles are arranged in a definite direction with appropriate spacings between them so that the mud adhered to shoes can be removed by the piles and collected in the grooves formed between the ridges. Thus, the removal of mud from the present matting is very easy as compared with a conventional one.
