I'm thinking maybe the addition of some swiveling bars, attached to the risers that swing down and keep the new parts from falling off the existing dinette might work, if you don't have another solution. Maybe only needed on the side that isn't up against a wall.
To answer your question start by looking at the 1st picture (the before one) you will notice that actually the dinette backrest are an arch.
So the bunk is composed of 4 parts. 2 are the bed rails side by side and 2 others are the risers. Let's look at the risers with orientation, width of the coach and length of the coach. So width left to right the risers actually have the same matching arch built in and on the length side there are 2 stoppers (the wood panel goes down 4 inches over the arches).
Now in picture 2 you will see by enlarging that the bed rail are attached to the risers with screw handles (you can see 2 in the picture) making this setup extremely solid.
