For the most part we will be driving with the 3rd row down and would like the rear cargo mat to cover the entire cargo area including the 3rd row seats which are folded down. Does anybody have this mat? If so, I am wondering if you do use the 3rd row for passengers, does the mat somewhat easily hinge (and not flop over on itself)? I know there is a small sidewall on these mats which will pinch at the fold point. I'm curious if anybody has experience with this mat and its usefulness with the 3rd row seats both up & down.
