I think I'm understanding what you're asking. On my Scamp
the top (or back support cushion/plywood) actually sat behind the bottom cushion. When the top was flipped up to create the top bunk, the bottom cushion was then pushed toward the front of the trailer (where the top cushion had been). That left about 2-3 inches in the front of the bottom cushion, plenty of room for the poles to fit into the brackets on the bottom gaucho deck. Since they didn't touch the cushions, nothing got smooched.
Bad description, but is this what you're asking
