I have 2 kids with one more on the way. Just ordered 2 leather "third row" seats from
http://www.littlepassengerseats.com that are mounted to the cargo tie downs. The owners are really nice folks, and very safety conscious, spoke with them directly when I placed my order. The picture shows the seat facing sideways, but the owners are redesigning the mounting bracket so that the seats can face forward, backward or to the side. The new bracket will also require one hole to be drilled to stabilize the seat a little better. I did not want to drill a hole so I asked them for the old bracket which does not require drilling, but can only be mounted in the sideways position. There is a shoulder seat belt included.
