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.

I LOVE this bed!! Something has been holding me back in making a bed despite loving other styles that have been posted. Hubby and I both love this style.

I'm in love with the modern furniture too, I'm so glad you've shared these ideas too!

Were you ever able to do the plans for that credenza from (I think) last month that you'd shown with the modern desk? If not, I understand- you must be super busy, and I'm definitely willing to wait :)

Lexsmommy, I would still add the corner bracing because it will keep your bed square and give you a support to screw your legs too. :)

I need to make a raised dog bed & I'm thinking of using this design.

Currently, my dog's bed sits on top of a large ottoman. He lays on it all day long & stares out the window.

I'm thinking of modifying this design, so it holds a dog bed rather than a mattress.

Do you think there's anything I should specifically consider when modifying this to a dog bed?

I would like to make a full size and a twin size. Does anyone know how to adjust the measurements? I recently purchased a home and have never made any furniture or anything for that matter.

I'm thinking of making this, but king size. Has anyone worked out the changes in dimensions yet? The west elm website lists the queen sizw as 62"wx83"dx9.25"h, and the king size as 78"wx83"dx9.25"h.
