The rubber base tray mat is durable and holds all the mud, snow, dirt, and other debris so it doesn’t fall onto the floor when scrubbing it off. This makes cleanup very easy. Simply shake the mat off outside then spray down with a hose or use a vacuum. The coir fiber bristles are made from the strong husks of coconuts, making it a natural, sustainable and environmentally-friendly choice. The coir fibers and rubber frame are all weather resistant and will not rot and breakdown like other wood framed products. They can withstand the coldest winters and hottest summers.
