Picture of One-legged bunk bed
Bunk beds are surprisingly expensive if you get a sturdy one, and the cheap ones feel pretty flimsy. This one is very easy to build from off-the-shelf lumber, and is rock-solid. Well, at least as solid as your house. This bed was made for my two small boys, but it's strong enough for anyone... as the second picture attests. Try doing that with a regular bunk bed! (actually, don't. It's not very comfortable. Lie on it instead).

Note: this bed worked so well I made two more, this time supported with a combination bookshelf/ladder.

Step 1: Materials

Picture of Materials
Four 2" x 4" x 10' construction lumber
Four 2" x 4" x 8' construction lumber
Two 4" x 3/4" x 10' finished knotty pine
One 6" x 3/4" x 10' finished knotty pine
One 8" x 3/4" x 10' finished knotty pine
Two 8' x 4' sheets of just about anything - plywood, mdf, particle board, whatever - the mattress sits on it so it could also be slats if you like. I used 1/2" plywood, because I had a project in mind for the offcuts.
3" deck screws
1 1/2" drywall screws
Eight 6" long 1/4" lag screws with washers
Ten 3" 1/4" bolts with nuts and washers
Two 6" 1/4" bolts with nuts and washers
Wood filler
You should be able to pick this up for about $150, less if you have some materials lying around.

Thanks for the design! I used it as a base to make a quad-bunk system.

Looks great. That's a serious amount of sleeping room right there!

I want to make this as a loft for my 6 yr old but I want to make it a full and I'm a little concerned about the single leg with the extra size. Any suggestions?

Well, remember that the other legs are the walls of your house, so they're plenty strong enough. This loft is built more like a deck than a bed!

yea I guess I'm just concerned about the leg moving. It's like a deck without pouring a cement footing. Without the lower bunk to secure the bottom of the leg.

Ah, OK, didn't spot you wanted a loft. Either skew nail the foot into the floor to prevent any movement, or perhaps try this other design I came up with for loft beds: http://www.instructables.com/id/Loft-beds-with-bookshelf-ladders/

So glad I found these plans... Saved me a ton of money and some room as well.... In a small room inches make a big difference... Excellent instuructables, thanks for posting

It looks really nice but it is kinda a pain to make beds with one or two edges pushed against the wall...
makendo (author)  SWV17874 years ago
Thanks. So that's why my boys hate making their beds...
I think your point is true of bunk beds in general rather than this one in particular; you can leave as big a gap as you like between the mattress and the wall for the bedding.

The problem is the wall, not the bunk. You have to kneel on the bed to put the sheets and blankets on the wall side and it's very awkward. It's also awkward on the railing side but not as much. Maybe someone will invent a sheet or device to make this easier no matter the size of the bed against the wall. We used to have bunk beds for the kids, and they just slept in cheap sleeping bags that got washed every week. Spreading them out flat "made the bed"!

My kids never make their beds no matter how we arrange them! This is a sweet design and seems faster to assemble than having 4 legs. Great Job!

Many thanks dbull. Yep, easy to make and the design is pretty forgiving.

I like it. Very nice and tidy.
makendo (author)  seamster4 years ago
Thanks seamster. Certainly no one seems to notice it is home made, much less that it's missing three legs...

Nice work. In a few years my kids will graduate to bunk beds (or loft beds) and this design would fit well in their rooms!
makendo (author)  jeff-o4 years ago
Thanks jeff-o. I have to build 2 more myself as my kids all get their own rooms, and these will probably be lofts.
