How to Add a Trundle to an IKEA KURA Bed: Attaching the Beds

This post is part of a tutorial on turning an IKEA KURA loft bed into a bunk bed over a trundle. For the other pages in this series, go to the Introduction and Disclaimer, the Parts List, Prepping the Wood, Part 1 of Assembly, Part 2 of Assembly, and Cross Bracing.

It's time to attach your bed base to your IKEA KURA loft bed. This is not a one-man job. You will probably need at least three people: two to lift the KURA and one to slide the bed base in underneath. Once you get this done, the rest is pretty easy.

Step One: Lining Up the Beds

Set the KURA down on top of the bed base. The open side should face toward the center of the room. Make sure that you line everything up so that the KURA is sitting directly on the bed you constructed. If you measured and cut everything correctly, it should all match up just about perfectly.

Step Two: Attaching the KURA

You need to drill vertical holes for screws to attach the KURA to the bed base on the long sides of the bed. See the photos for approximate screw placement along the back side of the bed. I used eight 3-inch screws, being careful to avoid the center support so as not to interfere with the screw that is already there.

The screw placement across the front needs to be more precise to avoid contact with the screws that will attach the front board to the bed. Using six 3-inch screws, I placed the first screw at approximately 7-3/8" from the inside leg on the non-ladder side of the bed and then spaced the rest of the screws at approximately 10-inch intervals. The final screw is approximately 1-3/8" from the inside ladder support.

Step Three: Attaching the Slats

We wanted the slats to be removable to enable easier cleaning under the bed, so we chose to attach the slats to each other using nylon straps in the IKEA style rather than attaching them to the bed itself. The slats rest on the ledges created by the 2x3s that protrude past the KURA frame. In order to do this, you will need a spacer that measures between 2-3/4 and 3 inches to ensure equal separation between slats. We used some old boards that were about 2-3/4 inches wide.

Put the 12 1x4 slats on the bed and use your spacer(s) to separate the boards the required amount. Starting at one end of the bed on the side nearest you, staple the nylon strap securely to the boards, continuing to space the wood out appropriately as you go along.

Once you have finished with the first strap, turn the slats around so that you can do the same along the other side. (If your bed is not against a wall, you can just go to the other side of the bed. No need to turn the slats.)

Step Four: Attaching the Front Board

Because there is no center support in the front of the bed due to the need to slide the trundle in and out and because we opted to use 2x3s for a more uniform look to match the KURA and to keep the bed height as low as possible, we needed something else to prevent the front 2x3 from bowing under heavy weight. We also wanted something that we could attach a bed rail to since the KURA's 2x2s are too wide for the IKEA VIKARE. We decided to attach a 1x6 across the front from the ladder to the opposite side of the bed.

Preparing this piece of wood is a little complicated because you need to create a small indentation where the large screw head for the IKEA KURA bed leg will be behind the board, otherwise the board will not lie flush against the KURA. We used a series of different sized drill bits to accomplish this, but any manner of tools could probably accomplish the job. The indentation needs to be a perfectly placed divot that has a diameter of about 5/8" and is about 1/8" deep.

In order to get the cut out in the right spot, you could measure where it needs to be. We just clamped the board to the bed and Chris banged on it a bit to leave a mark on the board from the screw head, and this worked well.

Whatever method you use to create the indentation, I highly recommend practicing on scrap wood first.

Once your cut out is made, the board should lie flush against the 2x3 of the bed base and the 2x2 of the KURA. Line the the lower edge of the board up with the bottom edge of the 2x3 and use books or scrap wood to hold it level while you clamp it in place as shown.

For this step,you will need to pay careful attention to screw size as well as placement. You will be creating two rows of staggered screws, and the screws that attach to the KURA itself will need to be 2 inches. The others should be 3 inches.

Beginning on the non-ladder side of the bed, put a 2-inch screw in the upper corner and a 3-inch screw in the lower corner as shown. The 3-inch screw should fit right into the place that you left for a screw when you were building the bed base in previous steps. I used a shorter drill bit for this step so that I would not be drilling very far into the rear board.

Next, you will need to place screw holes centered about ten inches from each other across the bottom of the board where they will go through into the 2x3 behind. You may have about a half inch extra when you are done, but that is okay as long as you place your final screw in the bottom corner similar to where you put it on the other side. Use 3-inch screws for this row.

For the row of screws going through the KURA 2x2, you will need to use 2-inch screws centered between the screws in the row below. See the photo for screw placement. Your final 2-inch screw should be placed in the ladder leg in the corner of your 1x6 as shown.

If you have placed your screws correctly, they should not interfere with the vertical screws you used in Step Two above.

Step Five: Finishing Touches

We chose to add handles and a guard rail to help our kids safely use the bed.

Sweetheart still rolls out of bed at night, so we attached the IKEA VIKARE as shown, and it matches the bed perfectly while being easy to remove when she no longer needs it.

Sunshine is a little short to be able to pull herself easily up the ladder since we raised the bed, so the handles we attached help her get up on her bed safely.

So there you have it! The IKEA KURA loft bed raised to allow for a bottom bunk and a trundle! Purchase a trundle separately or build one yourself using the trundle plans we will be sharing soon! (The plans as shared here in this tutorial allow for a trundle+mattress height of 9-3/4 inches, although it would be fairly simple to adjust the leg height prior to cutting the wood for your bed base in order to allow for a different trundle height.)

If you decide to use this tutorial, I would love to hear about it!

Living in a Small Home with Kids: 10 Reasons It Might Not Be Right for You

I recently read a great article over at The Tiny House asking "How Big Can a Tiny House Be?" In his post, Ethan ponders the definition of "tiny" when it come to little houses and concludes that the perfect "tiny" house is whatever size meets your needs, whether that is less than 100 square feet or much, much bigger. I think his conclusion is sound. He points out that even if a small house is too small for you, you can still benefit from some of the tenets of tiny house living. I would include living within your means and being mindful of the environmental impact of your chosen lifestyle as practices that anyone can enact, regardless of their home size.

If living large (or larger than we do!) is your thing, you'll hear no judgment from me. Living in a small home might sound romantic or adventurous, but the obvious truth is that there are downsides to the tiny house lifestyle. It's not all sunshine and roses, and you have to be committed to making i…

The Floorplan that We Call Home

I have been hoping to give you all a little more detail of what our home actually looks like, and when I was looking through some of my old photos and videos the other day, I stumbled upon this video footage of a home similar to ours that I took when we were still picking out our floorplan.
There are some minor differences since this is not our actual home, so some of the finish work is not the same. We have white appliances and a few more windows, particularly in the entry door at the foot of the stairs and in the dining area, where we have a bay window. We also have taped and textured walls, so it looks more like a real home. Our electric panel is accessed from the outdoors rather than the bedroom (which Chris says would be much more convenient, but I call it an eyesore), and we have extra storage cabinets next to the the door at the base of the stairs. We decided to forgo the porch options, so the front of our living room is covered in wall to wall windows with a sliding glass door…

IKEA KURA Trundle Upgrade Reveal!

How do you fit three twin beds into one <70 square foot bedroom? This is how...

After hours of planning and shopping and measuring and cutting and sanding and painting and drilling and building and painting some more, the IKEA KURA loft-bed to bunk-bed-over-trundle upgrade is finally finished, and I absolutely love how it turned out!

Here's another view looking in the mirror on the closet:

And here's what it looks like with the trundle pulled out:

I'm quite pleased with the entire structure. Lifting the bed seems to have actually made the KURA itself more solid as it wobbles and creaks much less now than it did before. The trundle is surprisingly comfortable, and I am eager to show you the simple hack we used to create a sliding trundle that an adult might actually be happy to sleep on regularly. (Hint: We built it around an IKEA LONSET slatted bed base.)

I took many photos of the entire process, so stay tuned for the free tutorial to see exactly how we added a trundle …
