DIY Padded Sofa – Metric

Instructions

1. 1. Make the Shelf and Braces

   • Start by ripping the one Shelf and three Braces from a sheet of 19mm thick sanded plywood, as shown in the cutting diagram. A saw guide makes it easy to make straight, accurate cuts. You can learn more in the How-To video below.
   • Next, cut each part to final length.
   • Set your Kreg Jig for 19mm thick material, and then drill pocket holes in the three Braces at the locations shown.
   • Sand the Braces and Shelf smooth, and set them aside for a later step.

2. 2. Make the Supports

   • Use the dimensions shown to lay out the first Support where shown on the sheet of plywood.
   • Now cut this Support using a jigsaw. For best results, cut just on the “waste” side of your layout lines, rather than trying to stay on the lines exactly.
   • Then sand the edges up to the layout lines to get them flat and smooth. With the first Support done, use it as a pattern to trace out the remaining three Supports on the plywood, as shown. After you sand all the edges flat and smooth, drill pocket holes drill pocket holes on the four Supports at the locations shown. Note there are two “left” side and two “right” side Supports that mirror one another.
   • Sand the faces smooth.

3. 3. Assemble the Supports and Braces

   • Start with two “left” Supports and one Brace.
   • Position the Brace where shown, making sure it sits straight and square, and then attach the Brace to the Supports using 32mm coarse-thread Kreg Screws.
   • Repeat the same process for the “right” Supports.

4. 4. Add the Center Brace

   With the two side assemblies together, you can now add the center Brace to complete the base frame. Notice the center Brace is set 19mm farther toward the front of the sofa than the side Braces. This is to make sure the center Brace pocket hole screws are offset from the side Braces and don’t hit each other.
