Seeing the result, I'll look into buying a more compressible high-density foam (urethane?) big enough to cover the same area and fill in the gap. I'll lay the Styrofoam sheet over that, bridging the transition, then lay the Roo mattress on top of that.
If that works I'll bond the Styrofoam to the urethane, split it down the middle, and create a hinge with tape of some kind. I'll orient the split perpindicular to the split in the regular mattress.
Now, why couldn't Forest River put a thick layer of urethane foam on the bottom of their fancy inner-spring mattress, filling in the gap the same way? They'd only have to do it for the back bunk.
Considering the care they seem to put into everything else, this is inconsistent.
