My wife would like me to make a bunk bed for our daughters by next year, so I’m starting now. I need to make a frame for a twin bed that can be lofted above a full bed frame, that I will make by next year, hopefully. I was thinking of making the legs out of 8/4 walnut, 2” wide. I have a piece that is around 80” long, so I could cut the posts for the entire length, cross cut them, so they look like one solid piece when lofted together. I was thinking of using 3/4” metal rods to line up the legs when lofted. My question is, will this be strong enough to hold up the kids or should I make the posts wider?

The rails will be out of maple with possibly a walnut strip inlayed. The headboard would be a curved maple top with walnut slats running up and down. And instead of a ladder, I was thinking of stairs up the side so it’s easier to climb up and down without falling.

Any help with the design is appreciated. I just want to make sure that it doesn’t fall apart when the girls are jumping around on it, because they will.

My son has a bunk bed that i bought cheap from WM because i was pressed for time. its posts are 2” square and its sturdy enough but if 2 girls are going to jump on it you might need to make it nearly bomb-proof. maybe you make the bottom bunk posts 3” and the top a little narrower? i did ditch the ladder and made stairs and put drawers in the side of them which worked well.

this bed is screwed together with 1/4” screws which periodically i re-tighten even though he doesnt really jump on it (low ceiling). so you might want to consider joinery that can be tightened periodically unless you are going to make really solid mortise and tenon with draw-bores so they never move.
