How to build a wooden daybed with a pull-out trundle

Building a wooden daybed with a pull-out trundle involves several steps. Below is a detailed guide on how to make one:

Materials Needed:

• Wooden Boards: For the frame, back, sides, and trundle.
  • 2x4s or 2x6s for the frame
  • 1x6s for the backrest and slats
  • Plywood for the base of the trundle and the daybed
• Screws (wood screws for assembling the frame and trundle)
• Wood Glue (for extra strength)
• Casters/Wheels (for the pull-out trundle)
• Wood Finish or Paint (optional, for finishing)

Tools Needed:

• Saw (circular or miter saw)
• Drill
• Screwdriver
• Measuring Tape
• Sandpaper (for smoothing rough edges)
• Wood clamps (optional, for gluing)
• Wood filler (to cover screw holes, optional)

Step 1: Build the Frame

1. Measure and Cut the Wood:

   • The daybed frame should be built with dimensions that match a standard mattress (e.g., twin or full size). For a standard twin mattress, cut the side rails to around 75″ in length, and the head and foot rails to the appropriate width (e.g., 38″ for a twin).
   • Use 2×4 or 2×6 lumber for the frame.

2. Assemble the Frame:

   • Attach the side rails to the head and foot rails using wood screws to form a rectangle. Ensure that all corners are square.
   • Use wood glue for added strength.

Step 2: Build the Backrest

1. Cut the Back Slats:

   • Use 1×6 boards to create the backrest. Measure and cut the slats to the desired height. Generally, the backrest can be around 36-42” tall.

2. Attach the Slats:

   • Secure the slats vertically to the top edge of the frame, ensuring they’re evenly spaced. You can screw the slats directly into the frame or attach them to horizontal 2×4 supports for added stability.

Step 3: Build the Trundle

1. Cut the Trundle Frame:

   • Build a frame that will slide under the daybed. The trundle should be about 2″ shorter than the main daybed frame in both length and width to allow it to slide out easily.
   • Use 2x4s for the trundle frame.

2. Add the Base:

   • Use plywood to create a sturdy base for the trundle. Cut the plywood to fit the size of the trundle frame.

3. Install Casters/Wheels:

   • Attach four heavy-duty casters to the corners of the trundle base to allow it to roll out smoothly.
   • Make sure the wheels are designed for weight-bearing, as the trundle will need to hold a mattress and support a person.

Step 4: Install the Slats or Plywood Base

1. Install Slats for the Daybed:

   • For the daybed’s mattress, install slats (typically 1x4s) across the frame, leaving a small gap between each. This will provide enough support for the mattress while allowing for ventilation.

2. Install the Trundle Slats or Plywood:

   • If you’re using slats for the trundle, repeat the same process as for the daybed, leaving enough room for the mattress to fit snugly.
   • Alternatively, use a plywood base for the trundle for a simpler build.

Step 5: Sand and Finish

1. Sand the Edges:

   • Sand all the rough edges and surfaces to prevent splinters and make the wood smoother.

2. Apply a Finish:

   • If desired, apply wood finish, paint, or stain to the wood to protect it and enhance its appearance. Let it dry before assembling the pieces.

Step 6: Assemble the Daybed and Trundle

1. Place the Trundle Under the Daybed:

   • Slide the trundle under the daybed. Make sure the wheels are working properly, and the trundle moves in and out smoothly.

2. Add the Mattress:

   • Place a mattress on the main daybed frame and on the trundle (if desired, use a thinner mattress for the trundle to ensure it fits properly under the main bed).

Step 7: Final Touches

• Add any decorative touches you like, such as cushions or throw pillows for the daybed, to make it comfortable and stylish.

With this setup, you’ll have a functional and versatile wooden daybed with a pull-out trundle, ideal for guest rooms or spaces where extra sleeping arrangements are needed!
