Mad Mats are truly an outdoor rug, designed to look like real living room carpet but are actually made of 98% recycled polypropylene plastic. Bright in color and long in durability, these mats are perfect for use in garden, patio, porch, pool and deck locations. They can be left out doors all year long during rain, snow or sunshine. The flat weaves and soft tubular threads don't absorb dirt or stains of any kind. When they get soiled they can be simply hosed off with a garden hose. They are truly the most carefree out door rug on the market today!
