Convertible Classic Bunk Bed

Submitted by sharonw on Mon, 06/22/2015 - 22:24

I modifed the Classic Bunk Bed and Cubby designs to create a convertible twin over full bunk bed. The bottom full-sized bunk can be rotated to be parallel to the wall (when my son sleeps there) or perpendicular to the wall (for when we have guests so they don't have to climb over one another). Changes I made were:

- I moved the ladder to the end of the bed to make room for the full-sized mattress.
- I added 1x2 treads to the ladder to make it easier on the feet.
- I raised the height of the top bunk. Finished height of the bed is 68" to add head room on the bottom bunk for taller people.
- I built 2 custom cubbies (full dimensions of each 37.5" x ~13.5" x 11.5") to support the added width of the full-sized bottom bunk. These cubbies can also be rotated to support the mattress in the perpendicular position for use as a guest bed (see pictures).
- I built an additional support that fits onto the back of each of the cubbies when they are turned to support the perpendicular guest bed (see pictures).
- I changed the end support rails for the bottom bunk to 1x12s that I painted to match the bed to be used as night stands when the bed is rotated to be a guest bed (see pictures).
- I used wood thread inserts and 1/4"-20 connector bolts (from Fastenal) to assemble the bed, so it would be easy to disassemble and reassemble.

Funny story - When we went to move it to the second story bedroom from the garage where I had finished it, the long sides wouldn't fit up our stairs!!! Our stairs have a tight 90 degree turn partway up. After all the hours I put in building and finishing it, I almost cried! Fortunately after using a straight edge blade to carefully cut through the paint, we unscrewed the upper most rail and were able to just barely get it up our stairs. I was so thankful I hadn't glued those boards on!
