I used this for a few days in a child seat when my child was potty training. Ultimately, I had no accidents in the child seat, so I stopped using it when I decided it wasn't necessary. I didn't have any accidents, so there are no urine stains, but there are signs of use like wrinkles since I had it in place. Color: Black *This is the short S type.
