Step 1

Take four of boards A and mark out the exact same arch in the panels. In the bed shown, the arch starts 6" in on either end and is 3" tall at the center point. Carefully cut out these arches using a jigsaw. Layout the headboard and footboard panels, as shown below. The below diagram does not show the arches cut out. This diagram shows how the spacers (C) are to be placed between each of the rails (B). Start with only 1 of the arched header boards and a straight header board on the bottom. NAIL ONLY THE SPACERS AND THE OUTERMOST RAILS - DO NOT NAIL THE MIDDLE 4 RAILS. Use 1 1/4" nails.

Step 2

Remove the middle four rails that were not nailed in the above step. Use a jigsaw to follow the line of the arch and trim off the ends of the red highlighted boards, as shown.

Sand the arched edge with a sander if necessary. Now replace the middle four rails. Nail with 1 1/4" nails.

Step 3

Now sandwich the remaning header boards as shown below, concealing the spacers. Use glue, and this time 2" nails. The diagram below illustrates these instructions. (This diagram does not show the arch cutout).

Step 4

Your completed center panel for the headboard should look like this diagram. Do the same for the footboard.

Step 5

Step 6

Add the 2x4 (Board E)to the top of the headboard as shown below. THE ARCHED HEADER 2X4 WILL FIT FLUSH WITH THE TOP OF THE BED. THIS IS NOT SHOWN BELOW. Add the 2x4 (Board G) to the top of the footboard. Board G will overhang the posts by 1/2" on both ends. On the headboard, add Board F to the top of Board E, allowing a 1" overhang on all

Step 7

Set the headboard and footboard aside. Build the following box out of the 2x2s. Notice how the shorter (I) 2x2s sit inside the longer (H) 2x2s. Use screws to screw through the outside of H into the end edge of (I). Use two screws per end.

Step 8

Add the siderails as shown below, leaving a 5/8" gap on either end. Screw through boards (H) into board (J). Doing this will hide your screw holes. Use 2 1/2" screws, screwing every foot all the way down the siderail.

Step 9

Notice how the boxspring frame will attach to the headboard and footboard. Screw into the headboard, and screw at an angle into the four posts. You want to be prepared for little monkeys

Be sure to measure your mattress/box-spring BEFORE building your frame! Our box was nearly an inch bigger and didn't fit, so we'll have to rebuild the frame.

Other than that, our daugter LOVES the bed! We'll be sending a photo soon!

This was our first wood project. My daughter is transitioning from her toddler bed and moving into a ‘big girl’ bed.

Ana, your measurements were perfect! Thank you for this FREE bed plan!

Price: The overall quality of this bed was sturdy and felt and looked like it cost a lot more. I am very impressed with the results.


Use corner braces so bed frames won’t be so flimsy.

Arches – (most difficult part) You need to have the proper tools for that. To do the arch, you need a big enough compass or something to make the arch. We did not have that. We used a semi circle cut glass top from our table in the living room as a template.

The small pieces for the arch were difficult to cut. The arch was supposed to be 3” high from the bottom but 6” in from the inside. Fine but what do you use to make the arch?

My little “jumping monkeys” made us a little uncomfortable with no extra support inside so we used 2x4’s as extra support for the frames.

We added corner brackets and L brackets. And our box spring did not fit the frame so we had to make adjustments.

All in all, my daughter lurvs her new bed!

Thanks again, Ana!
