A variation of the simple bunk beds made with old growth lumber stained with "honey" minwax stain and topped with 2 coats of satin minwax polyurethane . Each step on the ladder made with dado cuts, glued, and screwed and secured to each bed to add strength and take up less floor space. Used 8 inch HeadLOK screws to attach head and foot boards to posts and 2 7/8 inch to secure steps on the ladder as well as top boards to the head and foot boards. I cut down x4 HeadLOK bolts to 2 inches to secure rail to top bed so they didn't go through other side. Utilized non mortise bed rail brackets for easy assembly and disassembly; holds strong with no wobble even before ladder and plywood bottom. 3/4 plywood bottom screwed to the rails to better support mattress and add ridgidity. I screwed them so the bottom child doesn't push up on the mattress for the top child. All screws with the exception of the HeadLOK were counter sunk for a flush finish. All to say? This thing is strong and turned out beautifully.
