The cargo divider/cover does exactly that: it sticks (Velcro) to the fore edge of the cargo floor, can be installed either in a lower position (about 2 inches above said floor) or a higher position, flush with the plastic molded shoulder. It has a kangaroo pocket in the front. photo 11
Smart offers also a cargo net that anchor to the cargo floor, or a divider/net that anchors almost to the roof, half of it being solid, the rest a net. photo 10
