With the back seats folded down, 74 inches is the length (I need to do some 72 inch tables, they fit) to the back of the console, so if this is a folding bed frame and not very wide, you can put them between the seats up on the console well padded and held down and be careful on hitting your elbow on the end of them. Some years and models and packages have fold flat front passenger seat (like the 2010 SEL, Limited, Sport).
