The Canvasback Cargo Liner fits beautifully and protects the cargo space of the 5th Generation Toyota 4Runner. One big liner in the back and the two D rings are cut out on that also. Four separate pieces adhere to the back of the 40-20-40 2nd seat allowing for split seating. The middle seat has 2 pieces to cover all the carpet. When you move that seat by itself, it lengthens out so we needed another piece to keep you covered. Bumper Flap that connects to the end of the cargo liner by Hook/loop strips that are sewn on the Liner and the Flap. The Flap will attach right on top of the edge of the Liner. It is easy to take on and off or just flip it back into the car when you are not using it.
