Our bulletproof outdoor rugs have always been popular for patios, porches, decks, sunrooms, and back doors, but now they are finding a home in kitchens, bathrooms, laundry rooms, and stairways, where their strength really shines. They are 100% polypropylene, but you are hard-pressed to tell. Shake them out for regular maintenance, then bring out the hose, scrub brush, and bleach for the dirty jobs. Great for pet and kid households. We keep many samples in stock, which you can check out and bring home to check colors.
