We will not start that or Michel must set up a woodworker forum. On such beds I don't trust ikea. I have done 3 single layer and one 4 layer bunk beds. Handcrafted. No power tool at all. All chisel, saw and hand drill. I loved to have done it metall free, but found not enough room for the joints. (I'm not a japanese master and only pine wood at hand)

But a lot of reworked IKEA stuff. In the days of yore IKEA catalouge was full of idea how to rework stuff, so we got ideas.
