DIY Modular Rock Climbing Bunk Bed Fort

Bed time just got more exciting and a little dangerous for my boys. I made them a rock climbing bunk bed fort to replace the nonexistent beds they’ve been sleeping in for two years.

My plans were inspired by these from woodgears.ca and these from Ana White. The main difference in mine is the fort paneling which supports climbing holds. The typical ladder, for wimpy kids, is replaced by bouldering problems.

Below are my rough plans and a few pictures for each step. Until I receive thousands of emails requesting more details, I’ll leave it at this.

The Plans

There’s not much to it. The frame consists of

  • 2 by 4s at the posts and for some of the rail pieces and panel support
  • 2 by 6s for the four mattress side rails and the four mattress headboard rails
  • 1 by 3s for slats and 2 by 2s screwed to the side rails to support the slats
  • 1 by 6s for paneling

These are mostly connected by hex bolts, with 2 and 3 inch screws here and there.

One side has paneling screwed to the rails, which are connected vertically by 2 by 4s. The other side consists only of the two 2 by 6 rails that support the mattresses, and an extra 2 by 4 rail for the top bed.

The head and foot are identical, except for the filler pieces that go above and below the side rails making all the posts two 2 by 4s thick. These filler pieces are on the left of one end and the right of the other.

Finally, I made a detachable paneled piece that can bolt on to either end, or just roam free as a separate bouldering section.

The Sides

Here I’ve pocked hole jigged the frame for the side that will be paneled.

The frame is finished and I’ve started screwing on the 1 by 6 panels from the back.

Here’s the rock climbing side, with panels and support pieces for the slats.

The other, non-climbing side of the bed is just the 2 by 6 rails for the bottom and top, each with slat support, and an extra 2 by 4 rail for the top to keep the mattress in.

The Ends

The ends are 2 by 4s and 2 by 6s butted up against the 2 by 4s that make up half of the posts.

Here are the two sides, side by side. The inside posts, with the gapped pieces, are the ones that take the non-climbing side rails. The climbing side is then bolted to the other posts. It rests on those bits of 2 by 4 at the bottom.

Finally, the extra paneled end piece. Those are 2 by 2s attached across the back. They slide just over the rails on the side you want to attach to, and two separate 2 by 4s then bolt through the rails into this paneled piece.

Assembly

The bed assembles with a few dozen hex bolts. I countersunk the bolts and the nuts and washers on the inside with a spade drill bit.

Last of all are the climbing holds. I carved these out of the left over pine, and bolted them in with t-nuts. More on this later.
