The 2016-2020 Kia Sorento Cargo Mat with Seat Back Protector features a dense nylon fiber carpeting upper half and a water-resistant rubberized under layer to prevent leaking through! It attaches to the back of the 3rd row seat's, so they can be up or down - you can even have one seat up, with one seat down because this item splits where the seats meet! The Sorento Carpeted Cargo Mat has raised outer edges to trap in dirt, oil or any liquids from escaping! The Sorento Cargo Mat takes seconds to put in and to take out for cleaning!
