I ripped two sheets of plywood at 16.5” using my circular saw. I then cut both sheets to 64” in length.
I stacked and glued the two sheets of plywood together.
The foam I used for this project is called Kaizen Foam. I cut two sheets that totaled to 64”x18” for the base and two ¾” strips measuring at 64” in length. I used spray adhesive to glue all the pieces together. The ¾” strips are glued on top of the longer side of the cushion. No strips are needed for the shorter side.
I leaned the plywood vertically against the wall and then applied double stick tape. I then pushed the foam onto the plywood to adhere the two pieces together.
I cut a piece of leather that was roughly 5” larger on all sides of the cushion. This gave me enough space to fold on top of the plywood and staple in place. A little tape was helpful in holding the first side evenly onto the plywood before stapling it on.
I positioned each hairpin leg 3” away from each corner and screwed them into place.
Looks great! My daughter is moving into an apartment at college, and as soon as I show her this, I know that it will be something that we will be working on this summer. Thanks!
