I recently built a platform for the back seat.  I suspect that something similar could be fabricated for many vehicles.  This was NOT my idea; picked it up from a truck forum that I can't link to thanks to my newness.  I will link to it once I've earned my keep.

I have been mulling over something similar for my explorer. There's a gap between the back seat and the middle seat when they are all laid down that the dogs tend to fall in. Just haven't worked out getting it in and out of the truck since it will have to be so big and I have to be able to still lift one of the seats up so they can get in. Is that outdoor carpet you wrapped it in? It looks like it's working well.

I have a Ford Escape and when the seats are folded down, it looks almost just like this! Except the back part of the back seat is leather, luckily they don't climb on it. First time I rode with the dogs, I didn't fold down the seats and didn't take much braking to send Mishka slipping forward so a set up like this is essential! Nice job!

It is outdoor carpet, yes. The plywood is 1/2" MDF (overkill but it's all the store had in that size). Took an hour just to pick up wood, hinges, and carpet in Home Depot because everybody wanted to love on doggo.

It's worked fantastically so far. I have since put holes on the backboard to clear the seat latches which I use to anchor her.
