The mat arrived with a large tear and the batting poking out. It was shipped without the promised carrying bag, and no shipping box or packaging - just wrapped in plastic! Probably a return from another customer! Wayfair did send another, but it is not worth buying. The top and underside are different materials, and neither is durable, thus the tear. The flimsy material is also not water repellent, and I expect it will end up in the trash soon. I only bought this mat because another retailer no longer offers the very good mats they used to sell.
