These should not be advertised as outdoor mats. The picture and description is very deceiving. In no way are they heavy duty. The previous outdoor mats I needed to replace after many years of use, had a heavy rubber backing, these do not. The carpet part is very plush, thought or appeared to have a Berber type finish. They look exactly like a bath mat I have. As bath mat it is great, but definitely not outdoor or areas that may get heavy use.
