Easily installed and fits perfectly with no slipping on vinyl floor. Since the vinyl floor is smooth and slick, wasn't sure it these would work but they fit the contours quite well so they don't slip and move around. They are pretty close to a perfect fit but they don't slip around which was the most important feature to me. Wish they had my tan floor color but black seems to be fine.
