King Size Metal Bed Frame – So, first of all, let’s just pause for a moment to talk about the fact that you all rocked my metaphorical socks off last week when we shared. I guess I’ve been building it up for so long, I started to doubt myself in the final hour. I’ve never done a total room makeover before, let alone shared it with blogland.
I braced myself for whatever responses would come our way; even if you asked for my resignation as DIY blogger. (Now, you see why I became a theatre teacher; melodrama runs through my veins.)
Then, you all had the nerve to blow my expectations out of the water with some of the most enthusiastic and supportive comments we have ever received…ever.
Okay, be honest, guys: did my Mom put you up to this? Or did you maybe drink a jug of Kindness Kool-Aid before reading that post? Because it was kind of unbelievable. And I’m so glad I don’t have to resign because I kinda sorta really love this whole blogging thing. Thanks, friends!
Alright now I’m going to actually hush up for once (what?!) and let my husband take over the rest of this blog post. Because when it comes to building a custom king size bed frame, well, he’s your man! He planned out the design, purchased the materials, and built that sucker all himself, so trust me, you want to hear it from him and not me.

- 11 Best King Size Metal Bed Frame Design DIY Ideas
1. Build the I-Beams
We constructed a king-size bed, adjust the lumber sizes to match the size of your bed. First thing to build for the bed is the cross section. Start by building four I beams with 3/4″ maple plywood at 6-3/4″ x 80-1/2″. Take your caps and place them over the center of each end of the vertical piece. When you look at these from the side, they form an “I” shape. Set two of these I-beams aside.
2. Build the U-Beams
Make two U beams by using 3/4″ maple plywood at 6-3/4″ x 80-1/2″. Add caps to the vertical pieces, only this time, make sure the caps are flush to one side. When you look at these from the side, they form an “U” shape. Set one of the U beams to the side.
3. Assemble the Frame
Start putting the frame together by building the bed frame in two separate pieces, so it will be easier to move to the bedroom. Lay the I and U beams out with the U beam on the end, flush side facing outwards. Place an I beam 11-1/4 inches from the U beam, and then take the second I beam and place it 12-1/2 inches on center from that.
4. Attach the Beams and Cap Pieces
Take one of the facing beams and place it across the end of the I and U beams, securing it with glue and nails. Repeat this process at the opposite end. Take two cap pieces and attach them between the two facing beams, one on top and one on bottom.
5. Attach the Vertical Piece
Take the center vertical piece and attach it to the open end, securing it to the two cap pieces you just added. Repeat the steps above to make the second matching frame. Paint the outside of the frame your desired color.
6. Make the Bed Trim
To make the trim for the bed, make a three-inch rabbet cut at 1-1/2 inches deep. For the side pieces, start two inches from one end and cut 88 inches down one side of the trim piece. Stop short six inches from the opposite end. For the foot trim piece, make the rabbet cut all the way down one side. Paint the trim your desired color.
7. Attach the Platform Pieces
Cut out the platform pieces and attach the side platforms to both frame pieces using countersink screws. Paint the edges of the platforms
8. Assemble the Bed Frame
To assemble the bed frame, add the trim by placing the rabbet cut over the edge of the platform, making the trim flush with the platform. The trim should stick out 6 inches from the foot of the bed frame. Drill pilot holes from underneath the trim and attach with countersink screws.
9 Attach the Frame Pieces
Once the trim is attached, take the two frame pieces and attach them together in the center using countersink screws.
10. Attach the Center Platform
To finish, put the center platform in place and attach it using countersink screws.
