The Secure Mat is made of 100% top-grade Microban & Loofah fabrics — a quick-draining, anti-bacteria material that lets water through and fully drains it at the same time without leaving any ground for mold growth. And since Microban & Loofah don’t ever need to be washed or lose their draining power, it can keep your bathtub & shower safe, non-slippery, dry, & safe for decades.
