Step 1

Build the box out of the 1x8s as shown above.

Step 2

Adjust the bed frame for square and fasten the corner supports in the corners as shown above. Keep the top edges flush. This will be the bottom of your bed frame.

Step 3

Mark the end rails 30″ in and fasten the center support to the end rails using 2″ screws and glue or pocket holes from the inside. Keep top edges flush. This will be the bottom of the bed.

Step 4

Flip the bed frame over and mark the side rails down 2 inches on both sides. Attach the cleats with 2″ screws and glue, screwing every 6 to 8 inches.

Step 5

Step 6

Attaching the legs is easy. Simply line up the legs with the outside corners of the bed frame and screw through the corner supports into the top of the leg blocks. Use at least 2 screws. You could easily attach a different type of foot to the bed in the same manner.

Step 7

Lay your slats on top of the cleats and screw down. Also screw to the center support. Space slats approximately 4″ apart.

Finishing Instructions
Preparation Instructions
Fill all holes with wood filler. Let dry completely and sand with coarse sand paper. Refill holes with filler, and let dry completely. Sand again, this time with medium grit sandpaper. Then sand with fine sandpaper. Vacuum with a soft bristled brush to remove any residue. Then wipe clean with a damp cloth. Let dry. Apply primer and paint for a painted finish, wood conditioner and stain for a stained finish. Finish with a clear coat if necessary. Of course you would have skipped all of these steps if you were using fabric.

Thanks so much for these plans! I was totally stalking West Elms site for the narrow leg bed and bedside table. Thanks to the confidence I got doing the storage cubes, I shall now attempt to make my bedroom FAB-ulous with modern-style furniture! (love your simple modern designs!)

My question is about how to make the legs from the narrow leg collection? Should I use 2X4s? or 2X6s? I'm having a hard visualizing their dimensions - is the top 3 1/2"? What do you think? Would love some professional guidance!…

Hey guys!

I noticed that a lot of you were looking for the dimensions for a full sized bed, and I just made this over the weekend. Here is what I made for a full:

End Rails: 2 1x8 @ 55 1/2"
Side Rails: 2 1x8 @ 76"
Center Support: 1 2x6 @ 78 1/2"
Cleats: 2 2x2 @ 78 1/2"
Slats: 13 1x3 @ 55 1/2"

Kept the same:
Corner Supports: 4 2×6 @ 5 1/2″ cut at 45 degree angles

For the legs, we ended up just getting an extra 4x4 and cutting that @ 5" a piece to give it an extra 2" of height than Ana's plan.

Onto the headboard next weekend! Will post pictures when I'm done. Hopefully this helps!

Thanks for the great plans, Ana! You made this easy!
