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 have a question regarding weight limits on these type of slat board bed frames. Anyone have any idea what they are? Would a 300+ pound person be in trouble of breaking the boards? We love some of these plans but have some larger relatives who would likely be using them.

Also, love the site! I'm also up here in Alaska and it's great to see some great craft ideas for up here where it's hard to get stuff! :)

Please don't stop with the modern or simple furniture. That's the reason I found, subscribed, and check your site daily!!!

thank you soo much for posting this bed! while I like your rustic, farmhouse style furniture plans, I love the simple, modern style furniture. I can not wait to make this bed. I showed my husband the plans and he's dubious that I can pull it off on my own.

Question about the modification for a king size. When you say to add a center leg--do you mean one just like the other four chunky ones? Or something else entirely? I need a visual for that one! I love this plan--we have been looking at platform beds for a while now, and this one is almost exactly what we need!

You read my mind! I was about to try to design something simple like this myself because the "captain's bed" was a little involved for us, & lo & behold, look what I found when I opened my Google Reader!

My own alteration on the plan will be to raise it up twice as high, so I can fit some of those long plastic storage boxes underneath. And there might be a linen dust ruffle with inverted knife pleats to cover it all, so I can have another place to indulge my love of fabric!

Thanks, Ana! This is just what I needed. (Plus, I love the mix of modern & farmhouse. Variety is the spice of life!)

This is what I have been dreaming of for a bed and night stands! Thank you so much. There is no way we would be able to afford this suite.

I absolutely love the modern furniture you have been posting. I'm hoping you will post a modern dresser to match the nightstands.
