This Triple Bunk Bed plan is a staggered design with the middle bunk offset. This allows it to fit under the common 8 foot ceiling height without compromising head room, by assuming half of the bed is for the footer and does not require as much height.
Despite the overall size of the project, it uses very simple construction methods. All cuts are right angles, and all screws go strait through flat surfaces. The biggest challenge is getting everything square, and simply getting all of the pieces organized for assembly.
