DIY Folding Bunk Bed Plans. Good, but plenty of room for improvement. Ladder should be between beds. Outside corners should not overlap - either mitre or fold the corners. Here, these beds are only good for children as with the load of an adult they would break at the bolts that go through the front uprights. This can be remedied by adding a common member to the outside ends that will butt up against the front of the uprights when closed, and be an outside leg when they are open.
