Introduction: Easy and Strong 2x4 & 2x6 Bunk Bed

About: Build instead of buy....most of the time.

I’ve built a lot of these bunk beds in the past and recently built one for my own home. This is a super easy build as the materials are all common construction grade pine and every cut is a 90 degree cut so there are no complicated angles. The construction is with wood screws and pocket hole screws. Because all of the screws are installed from the inside there are no screw heads or carriage bolts showing on the outside. This gives the bunk bed a nice clean appearance. Both sides double as a ladder.

The overall measurements of the bunk bed are 72″ tall with a footprint of 81-1/2″ long by 45-1/2″ wide. The bed frames are sized to accept a standard twin mattress.

I'll walk you through the building process with this instructable to give you the overall process of building it. For those interested in the specifics of every dimension and cut I do have plans available and a link to those is in the last section of this instructable. The following is a rough list for materials:

  • Four 2x6x10'
  • Four 2x6x8'
  • Seven 2x4x10'
  • Twelve 2x4x8'
  • Wood screws, pocket hole screws, brad nails
  • Wood glue

A rough list of tools to complete this project:

  • Drill
  • Miter saw or circular saw and speed square
  • Table saw is optional
  • Pocket hole jig. Super cheap ones work fine.

Using power tools incorrectly can be dangerous. If you are at all uncomfortable doing something don't do it. You can walk with a wooden leg and hold things with a wooden hand but you can't see with a wooden eye. Wear your safety glasses.

Step 1: Cutting Parts

The bed frames need to be built first because their overall width determines the length of the ladder rungs. Regular construction grade pine 2x6s are cut for the frames. I used my miter saw for this step. (pic 1)

I'm trying to achieve an aged look with the finishing process so I don't need to be super critical when sanding. I don't want everything to be super smooth but I do want to remove the manufacture stamp marks. (pic 2)

So to make the process much faster I decided to use my thickness planer instead of sanding. Just a few slight passes to remove the stamp marks. Having a planer is obviously not 100% necessary to build the bed but for me it did save some time and effort cleaning up the boards. (pic 3)

Step 2: The Bed Frames

The frame pieces are joined together with wood glue and pocket hole screws. These will be hidden by the mattresses and nobody will ever see them. The pocket holes are on the inside of the short rails of each bed frame. (pic 1)

2x2 material is needed for the slats to rest on in this bunk bed. For me it's cheaper to purchase 2x4 stock and make my own 2x2s so that's the route I went. Again, a table saw is not necessary for this build. If you don't have a table saw or simply do not want to make your own 2x2 stock then you can purchase a few pieces of pre-made 2x2. (pic 2)

These are glued and screwed to the inside of the bed frames along the bottom edge. (pic 3)

Step 3: The Slats

Typically when you see removable bed slats they are either 1x4 or 1x6 material. For a twin size mattress those sizes are definitely acceptable. But again this was an area where purchasing regular 2x4 material was less expensive per linear foot than 1x4 material. To reduce a little thickness and also create a spacer block a rabbet is cut on each end of the slat material. I slapped together a couple jigs to show you how easy it is to make these cuts with a circular saw if that's the only saw you are using for this project. This first jig will make the 1/2” deep cut. (pic 1)

And this second jig will make the second cut of the rabbet. It's just a piece of plywood with a spacer clamped to the end of the slat to position the circular saw blade 1/2” into the material. The resulting cut creates the rabbet on the slat and the offcut will be used in a later step. Most often taking the time to make a quick throw away jig for a project will increase accuracy and also save time in the long run. (pic 2)

I made those two jigs for the sole purpose of showing you that you don't need an expensive bandsaw or table saw to complete this project. Technically every cut on this project can be made with a cheap circular saw. However, that was just a demonstration. I used my bandsaw to make the remainder of the rabbet cuts to save some time. (pic 3)

The first slat to go in is the center slat. It's also the only slat that is secured with screws. The rest of the slats will be floating in place. (pic 4)

Next, all of the offcuts were glued and tacked with a couple brad nails. A scrap piece of 2x4 was used as a spacer block. The only purpose these serve is to keep the slats from sliding around over time. (pic 5)

Step 4: The Leg Assemblies

With the frames done I could focus my attention on the legs. Each leg is a L shaped formed by securing a 2x4 to a 2x6. The 2x4 will receive the pocket holes. The spacing of these pocket holes is critical though. Not necessarily for strength but instead for appearance purposes. These needed to be placed so that they would be covered up when installing the ladder rungs. (pic 1)

I didn't realize it until I had already built my legs but the 2x6 stock I purchased was a little less than perfect. Most of it had a bunch of machine roller marks on the ends. To remove them I used my block plane but now that I think of it I should have just ran the assembled leg through the table saw to remove a saw blade width from the bad side. (pic 2)

The ladder rungs were cut next. They will be secured to the 2x4 side of the legs to cover up the pocket hole screws. I used a couple spacer blocks to indicate where I could predrill holes. (pic 3)

Glue and screws secures the ladder rungs to a left leg to a right leg. The only thing to be concerned with here is to make sure the ladder rungs stay perpendicular to the legs and that they cover up the pocket hole screws on the legs. (pic 4)

The final pieces were the frame locating blocks. These will support the bed frames at the proper height during assembly. One block was used for every corner of each bed frame. (pic 5)

Step 5: Final Assembly

I thought I was going to have my hands full with assembly but it ended up being super easy. To start I slid one side of the lower bed frame into place and used a quick clamp to hold it in place. Then did the same to the other side and held it with a clamp too. (pic 1)

Because the clamps were the only thing holding the lower frame I could set the top bed frame in from above and slightly push out one side to get it in place. Again, a pair of clamps to hold everything in place as I screwed it down. (pic 2)

This part may seem a little overkill but I don't think it is. Each inside corner of the bed frame receives 8 screws to mount the frames to the legs. Two into the 2x4 side of the legs and six into the 2x6 side of the leg. This grid of screws creates a lot of conflicting geometry that will prevent racking of the entire bed. This may be a tiny bit cumbersome to remove all of the screws when moving the bed but for a furniture item that will spend 99.99% of it's life serving a purpose and not in transit I think it's just fine. (pic 3)

Finally the remainder of the slats can be installed. These slats are really strong. I weigh 190 pounds and put all of my weight on the center of one individual slat with no problems at all. I have no clue what the max capacity of this bunk bed is but it's got to be a lot considering all of the weight will be distributed amongst all of the slats and then to all four of the legs. (pic 4)

Because both ends are the ladders themselves it doesn't matter what way you position the bed. You can get on top bunk from both sides. As you can see I didn't put the guard rail on the top bunk. That's a personal choice to make but for those who are interested one is included in the plan. (pic 5)

Step 6: Finishing

As you can see in this first pic I installed this in the room without finishing it first. I had family visiting so I figured I would finish when time was available and it could be used in the mean time. (pic 1)

Since then I removed the bed and finished it with a wax only finish. I used Rustic Pine Briwax. This wax finish allows for easy touch-ups down the road as the bed gets abused and it also allows for the wood to naturally pick up character as people interact with it. Also in this picture you can see a pair of matching 2x10 bookcases which I will cover in an upcoming instructable. This bed is the first piece of an entire dimensional lumber bedroom furniture set I will be making for this room. (pic 2)

I hope you were able to find some inspiration in this project and are able to make one of your own. This is a really inexpensive build and a solid design that will last for years and years. Regardless of if you use my bunk bed plan, someone else's, or design your own I wish you luck with the build! Building it yourself is incredibly rewarding, you will get a much better product, and will save you a lot of money. For those interested I do have a detailed set of plans available for this exact bunk bed.

Question 5 months ago on Step 6

I have a question about the placement of the pocket holes in the bed frames. You drilled them on the inside of the frame, which means the screws point to the edge of the frame. Isn't that weaker than drilling them from the outside in? The holes would be covered by the legs anyways, so it's not an aestetic issue.

I liked the design enough to want to build it, and paid for the premium membership to download the .pdf plans. I was extremely disappointed to find the .pdf was simply a print of the website - no additional information, no dimensions, no cut list. What's the point of that? I can print the website without the .pdf file. This is bad case of bait and switch - get my money and deliver nothing I didn't already have.

Question 1 year ago on Step 6

I'd like to create a rustic wood bunk bed that divides a room in half, so that the top bunk has one side of the room. And the bottom bunk has the other side of the room. I've never built anything. Is there somewhere that I can get dimensions to work with for a basic bunk bed?

For the frames, you appear to be drilling your pocket holes in the direction away from the grain. Should you not be drilling them from the outside into the grain of the frame lengths?

Hi Jay,

Planning on building 6 of these (with your plans) for a bunkhouse we have under construction. I'd like to build these using the dimensions for a twin XL mattress, which is 5" longer than a standard one. Do you think there will be a problem with extending the bed frames 5"? I will, at the very least, add an extra support for each bunk under the mattress. Love the design!

This gentleman charges $9.99 for his plans on his site. Contains all the details and is very much worth it in my honest opinion.

Question 2 years ago

Hello i was wondering if you could help me with dimensions and cut sizes for a different type of bunk bed. I have to make room for my little ones and I'm afraid my oldest will fall so I'd like to include stairs. I also have an image.

Our youngest was two when she started using. Fell once the first night bc three of them we fooling around. She learnt from experience and hasn’t since. This despite that we added an extra rung to make it easier for her. Even with stairs, a fall could happen if one is fooling around...
Hope this helps you decide.

Any ideas for making this a two piece set to avoid the need to take it apart when moving it in and out of a bedroom?

Answer 2 years ago

Even if cut legs in half, to use separately or to reassemble as bunk (would need some sort of bolt to keep together), each piece would likely be heavier than most people would want to move. If we ever move ours to another room, it’ll be separated into four pieces, plus the separated slats.

Question 2 years ago on Step 6

Ive never built anything before, but I’m considering trying this (despite having no tools... I’m hoping to borrow some)

My question: I have teens so I need this bed to be very strong. Would just upping the size of the lumber do the trick? Or do I need to add some kind of braces to it? Or is it fine as is?
