Abstract
The present invention relates to slip-resistant machine washable floor mats particularly suitable for use in motor vehicles. The floor mats have an upper carpet fabric layer attached with adhesive or by flame lamination to a lower layer of coarse-celled reticulated polyurethane foam having pore sizes within the range of 3 to 80 pores per linear inch (about 0.19 to about 0.02 inch cell diameter). The floor mat has an air permeability greater than about 5 (ft.sup.3 /min.)/ft.sup.2 at 0.5 inch of water pressure drop, which enhances the washing and drying ability of the entire mat.
