Yes there is wood in this project!
The dog and I are headed out east next month and I wanted to give him some room in my extended cab pickup. So I took out the back seat, removed the fold-down center console from the front seats, and built this platform. It’s a 2×6 frame underneath a 1/2” plywood bottom. That brings it up even with the center console. With the seat removed, the back of the cab was just exposed sound-proofing material so I took another piece of plywood and made two metal clips to go on the back so that it drops down into the old seat-back brackets. I added the carpet and now he’s got almost 15 square feet to chill out in the back and he can just walk right through the center to the front seat when he wants to stick his head out the window. I didn’t want to move the jack so I made a small cut-out in the plywood and put a slit in the carpet so it hangs over it. I also made sure to size it so that the carpeted platform goes door to door so there is no place for his toys to fall into and get lost.
Total cost was $45 for the carpeting (I splurged a bit), 2 scrap 2×6 and part of one scrap 2×4. Total time was under 3 hours counting removal of the old seat.
