I am planning to build this triple bunk this weekend. I plan to add “cleats” (not sure if this is the correct word) in the form of 2inx4in’s between the sections, on the inner side of the support posts. The bed frame will be resting on these cleats with the bed frame and the cleats glued and screwed into the long corner posts. Does this sound like satisfactory structural support if the bed were occupied by large adults? We are trying to avoid the bed frames becoming victim to a sheer force disaster and collapsing.
