I put some along the rear edge of the mat and thought it would work but was still moving around yesterday. I need to add more I think but need to make sure I am not blocking where the part attached the 3rd moves when the seat is raised and lowered.I actually have some of this already. Will give it a try. The part that attaches to the 3rd row does ok. The separate liner for the floor is terrible. Actually gets in the way when trying to load anything heavy. Hopefully this helps.
