2017 extended cab cushion?

Hi--We've got an old Australian Shepherd who mostly sleeps on the back seats of our extended cab. I'm wondering if anyone has rigged a bench seat cushion that would make her more comfortable? After sitting back there myself, I can testify that the seats are really bad. Any suggestions?

 

Dogs find the weirdest things comfortable. My dog lays on top of his bones every once in a while

 

Try searching for dog platforms

Several have done it, but it may be a little more than you are looking for.

 

I’d think the easiest would be to cut some 1/2” plywood to fit and support on the end with 2x4’s, then throw one of those pet beds on top.
