Industrial grade, rubber-backed floor mat. Was used outdoors so already dusty, and I had cut an irregular shape out of the corner about 6” to fit around a railing. Pattern looks like a waffle (repeating squares) of polyester.

Brand is TrafficMaster Fiber and Rubber Commercial Door Mat, found at Home Depot. Heat, stain, and water resistant. 90% recycled materials.

Free. Side porch pick up.

Let me know if you are interested and I will set it out for you and provide an address (and so I can tell others it is no longer available).

I think it is 3 x 5. It is already rolled up.
