Instructions
Step 1

Attach 2x2 cleats flush to the back of the legs, with 2-1/2" screws
NOTE: Pocket hole users can skip this step
Step 2

Layout the 1x6 headboard panels, and measure the overall width.
Cut 1x4 boards to this measurement.
Attach 1x6 boards to the 1x4s with glue and 1-1/4" brad nails from the back side to hide nail holes.
Make sure you apply glue between the 1x6 boards as you go.
Check to make sure that the panel is constructed square (NOT a parallelogram)
POCKET HOLE USERS: Attach 1x4s to the 4x4 legs with 3/4" pocket holes and 1-1/4" pocket hole screws. Then nail the 1x6s to the 1x4s inside the headboard panel.
Step 3

Attach panel to the 2x2 cleats with 2-1/2" screws and glue. Also attach with a few 1-1/4" nails through front side into the 2x2 cleat where there is no 1x4.
POCKET HOLE USERS can skip this step
Step 4

Measure the top overall width. Cut a 2x4 to this width. Attach with glue and screws to top of headboard.
Step 5

Cut a 2x6 2" longer than the 2x4.
Attach with 1" overhang on all sides with 2-1/2" screws and glue.
This completes the headboard build.
Step 6

The footboard is constructed the same as the headboard, with the exception of the 2x2 cleats on the back so that the siderail cleats can notch in.
If you have trouble with your smaller 2x2 splitting try predrilling holes.
Step 7

Finish construction of the footboard exactly as you did the headboard.
Step 8

Attach siderail cleats inside the footboard and to the headboard legs. Use 2-1/2" screws to secure.
This completes the footboard.
Consider painting or staining your footboards and headboards and siderails now - then move all the pieces into the room for final assembly.
Step 9

Attach headboard support piece between the siderail cleats.
Step 10

Build the center legs - space the legs about 1/3 the way down - you don't have to be exact here.
Step 11

Attach the center legs inside the bed, splitting the spacing by about 1/3
Step 12

Attach siderails to the siderail cleats.
We recommend using brackets to attach siderails at the top to the headboard and footboard.
POCKET HOLE USERS: Drill a pocket hole at the top and attach.
Step 13

Cut slats and lay about 4" apart in the bed.
Screw down with 2-1/2" screws.
We apologize if there was an error in this plan. Please help us out and report any errors here.

Answer to the side rails question
I did a version of this plan and measured 7" from the floor to the bottom of the bed rail. I've also got some detailed instructions on using the rail hardware if that helps anyone as well as some comments on my post about not using a box sring for the king version (I've done Queens and Fulls of this design as well).
Good building!

Frame with a box spring
I would like a way to make this bed come apart easily and noticed that some have used bed mortis brackets to mount on the out of the posts rather than on the inside with screws.. this is a great technique but by my by my calculations that would leave you an 83” in width from side rail to side rail versus the 76” that you end up with in this plan by putting the rails on the posts in the inside with screws.. I use a box spring and mattress and 2x10 as rails to hide the box spring as well.. so after lots of thinking if I mounted the rails on the front of the posts using the mortis brackets and shortened the headboard and footboard to 76” or 76.5 inches would this make up for the excess space that you get by not putting the rails on the inside of the posts? I am really needing something for a box spring to be used on this bed and the bed is easily taken apart... can you please help?
Respectfully,
Theresa

Thank you for updating this…
Thank you for updating this plan. It's so much easier now to follow for a standard king. Just in time too because our king mattress is on its way.

Could you explain further how you are attaching the center legs through the panel? Are you angling the screws from the center leg into the panel?

I notice that we are supposed to put screws into the footboard from the front paneling and top to secure the pieces of wood. How does one go about hiding these screw holes? Would wood filler or putty work?

Hi. We are almost done making this bed and super excited. We love the color you use in the first picture - what stains did you use/ do you have instructions on how we can make it look like this? Thank you!

If you can get a #8 that would be better. The #10s are so much harder to drive and tend to split wood more often.
