I decided to make a wall bed (Murphy bed) to save space and double as an office. This is for a full size bed.
2x8 - 12 ft (If I did it again I would have gotten 2x10)
2x4 - 10 ft
8in gate hinges - 2
Size 14 screws for gate - 8
Size 14 bolts and nuts - 2
A full size bunk bed frame
Step 1: Cut Board And Drill To Wall
Cut the 2x8 into 2 60" pieces. Drill them together and cut two more pieces to make supports. Then drill the back to the wall
Step 2: Drill Hinges On
Drill the hinges onto the 60" 2x4 first then onto the base.
Step 3: Attaching The Frame
So here is where I drilled the bolt into the 2x4 to attach the frame. If I would have gotten a 2x10 instead of 2x8 I could have had the 2x4 lay horizontal when the bed is laid down. Then I could have drilled the bolt through the thin part of the board. Instead I had to drill a hole in the middle of the board so I could get the nut on the bolt.
Step 4: Attach The Feet
Just drill a hole and bolt on
Step 5: The Mattress
Put the bed on and test it out. Then you need something to hold it while it's up. I chose bungee cords.
