We have an 8x20 we put out on longer stays or if the site will result in a lot of mud or sand being dragged in. We also got
this mat for just inside the door. It helps trap more dirt than a regular door mat. Since asserting, I have not been putting g our patio mat out on weekend stays and the fiver misstated pretty clean on the inside. As others have said, the patio mats look nice and help reduce dirt, they also help our dog's feet on gravel.
