How to Build a Bunk Bed

Constructing a freestanding bunk bed saves floor space since it can be placed against any wall in your home. The project is broken down into simple steps that include frame construction, attachment of corner posts and final assembly.

Highlights:

Step 1: Cut Lumber
Step 2: Create the Rails
Step 3: Form Frame
Step 4: Joining
Step 5: Mattress Platforms

Step 1: Cut Lumber

First, choose a strong sturdy material for the frame. These frames are from 6/4" pine. Using the mattress measurements as a guide, cut the wood for the frames.

Step 2: Create the Rails

Draw a curved form onto the long side pieces and rough cut with a jigsaw. Using a flush-cut router bit, clean up the edges to create a clean, uniform look.

Step 3: Form Frame

Attach the pieces together to form the frames. Cut and attach 1x2 strips to the insides for mattress supports. Next comes the corner posts. Cut four 4x4 pieces to the height you want your bunk beds to be.

Step 4: Joining

To join the beds, create a mortise and tenon joint. First, use a scrap piece of wood to mark out the width on one side, then flip it over and mark the depth of the frame on the next two sides. With a circular saw set to the same depth, make small cuts on both sides. Then chisel until smooth. Next, pre-drill holes and then attach the posts to the corners.

Step 5: Mattress Platforms

Once the top bed frame is attached, cut a mattress platform out of plywood and insert it over 1x4 supports. The bunk beds are now ready for mattresses and a great night of sleep.
