I bought one for each car. My larger dogs have been kept on the back seat and have not tried to jump over to the front seat. Unfortunately, my two Yorkshire Terriers just piled over the top (but they're bananas). This is not a reflection on the product, it's a great idea. I like the pockets in the front, great for extra storage. As my guys can see through the mesh, they don't feel so isolated on the back seat.
