Today we have a triple bunk bed plans pdf that we used to solve a space problem in our kids room. Growing up, I remember with fondness the battles over “space” and the closeness of late night chats with my siblings as I grew up sharing a room. Now that I am a mom,  I hope to give our kids the gift of comrade by through shared space.  With our recent adoption, space is at a premium and we decided now is the time to create a workable space for three kids to sleep in the same space. Our solution was this triple bunk bed plan.

How We Created This Bunk Bed Plan

We were inspired after seeing this how to build a bunk bed tutorial by  Handmade Dress where they had a triple stacked bunk. While we loved the plan, it was required to be screwed into the wall which might be a problem for us with moving kids around.  We wanted a more adaptable version of the triple bunk bed set, in case the kids decided to switch rooms, we have to move, or if they wanted to change the layout of the bunks.  

With the help of the friendly lumber assistants at our local hardware store, we were able to create our own freestanding triple bunks.

Supplies Needed to Build a TRiple Bunk

  • 18 carriage bolts and nuts.
  • 2×6 boards
  • 2×4 boards
  • 2×3 boards
  • 3 sheets of plywood – all cut to be 39 3/4″ x 75 inches.
  • Box of wood screws 3″ long.
  • Gel Stain
  • Rub-on Polyurethane

Tools to use or borrow for Building Project

  • Table Saw
  • Router*
  • Drill
  • Power Hand Sander – otherwise you’ll spend hours sanding!

*We were able to borrow a router, if not we would have rented one – we used it to mold the edges so they were slightly curved. It really added a polished look to the finished product. Note: We do have a circular saw, but we barely used it as the staff at our hardware store cut the wood for us which saved us work and helped us fit the pieces into our van.

Sizes to Cut the wood

Ladder Pieces for the Triple Bunk Bed

2×6 Boards

  • 6 boards 80″ long
  • 6 boards 40″ long {These will make the bed “box”}

2×4 Boards

  • 6 boards 66″ long
  • 2 boards 43 3/8″ long {Those will make the uprights for the top bunk}
  • 2 boards 40″ long
  • 2 boards 25 inches long {These will support the middle bunk}
  • 4 boards 20″ long {the steps of the ladders}
  • 16 boards 7 1/4″ long {These are the supports between steps in the ladder}

2×3 Boards

  • 2 boards 60″ long {Top Bunk’s guard rail}
  • 15 boards roughly 40″ long {NOTE:   These are the supports for the bed platforms.   If your wood is slightly bowed as ours was you may need to measure these after you get your bed box created and cut to fit}

Instructions to Put together the triple Bunk Bed Set

Here is the Diagram for Building the Triple Bunk Bed Set

Step 1: See Diagram “A”

  1. 66″ board & 1 – 43 3/8″ board: Make 2
  2. Put a 2×6 scrap on the bottom fot he 60″ board – do not screw it in, use only for placement.
  3. Screw the 43 3/8″ board over the scrap. The board will now be 4×4 except for where the beds sit

Step 2: See Diagram “B”

  1. 66″ boards, 2 – 20″ boards, 8 – 7 1/4″ boards: Make 2.
  2. Like before, use a scrap 2×6 to find where the first board starts.
  3. Screw a 7″ board about the 2×6 open slot so that the boards create a 4×4.
  4. Screw in the 20″ step, add another 7″ above it and then use the scrap 2×6 to reserve the space for the bed. Repeat until the ladder is “filled”.

Step 3: See Diagram “C”

  1. 40″ boards & 2 – 25″ boards. Screw them together so that the ends are notched, leaving space for the middle bunk to rest on the support.
  2. Make two legs.

Step 4: See Diagram “D”

  1. 80″ boards & 2 – 40″ boards. Make three bed boxes.
  2. Screw the boards together. Add cross rails for support (2×3 boards 40″ long). we used five supports per bunk.

Adding Side Rails to Your Bunk Bed

In our case, we kept the bunks without rails letting the older siblings sleep on the top bunks. If you want to add rails, create those with additional boards. Or if you want a temporary solution that can change over time, here are some bed rails you can grab with our affiliate link off of Amazon:

  1. Awesome! I love these! I don’t get these people claiming it needs 4×4 legs? Maybe their building one for their college kids? One bed is on the floor so there is no weight issue there, and my two oldest will be past 5th grade before they hit a combined 100lbs! And the ones criticizing the heights need to teach their kid to sleep with their heads at the other end of the bed! I do love the caster idea, being able to slide the bed in when their not using it is genius! This would be great for working on school projects or when it’s time to swap clothes seasons out of the attic! My three are all 4 and under my only dilemma is to start with one with toddler mattresses or just move onto the two size ones?

  2. I love this idea!
    But I am glad I aren’t the only one who thought the middle bed needs to be adjusted slightly, it seems too close to the head of the bottom bed, the child waking in middle of night could bump ibto it, I’m also not keen on the bits of wood sticking up, and no guard rail on top.
    Other then that.. few tweaks here n there, its good to go 🙂

  3. Hi there,
    Thank you for sharing this bunk bed plan, we are planning to build a similar one but with normal size single mattress 3ft, plus having the middle one as it is. The one problem I am find is the size of the boards do you have a measurement in height, width and length? I am from the UK and can’t work it out. Also I am thinking to add a sliding from the top bed to make it a bit fun for our daughter. Any ideas? Cheers

  4. This bed look absolutely perfect for our needs. Thank you so much. Might need to do some minor tweaking to meet our space needs but this is such a great jumping point. I love that you adapted the original design to be free standing. That is exactly what we were looking for!

  5. Hey! I just wanted to ask if you ever have any issues
    with hackers? My last blog (wordpress) was hacked and I ended up losing a few months of hard work due to no backup.
    Do you have any methods to stop hackers?

  6. It’s a good idea just not all that safe as it is, horizontal bracing and 4×4 legs would make a world of difference, if you don’t have room to slide 3rd bed to the right I would advise padding the end of it to avoid kid whacking there head on it if the shot up from a bad dream, imagine that suddenly waking from a bad dream and get whacked on the forehead, I can hear the screaming now 🙂
