I got the Yogi one (hammock with hard floor inserts) that has the orange trim that matches my RR.
Dog Car Seat Cover, Large Back Pet Car Seat Protectors with Mesh Viewing Window and Extra Cover for a Quick wash, 2 Seat Belt, Non-Scratch Waterproof Nonslip Dog Hammock for Cars Trucks and SUV : Amazon.ca: Pet Supplies
I like that it is easy to clean. The side door protection helps keep my dog from scratching up the door panels but does nothing for the drool on the windows. I just clean the windows as needed.
But I also like the one posted just above if you actually want to use the back seat as a back seat.
