I needed a simple bench for banquette seating in my dining room and I couldn't find one that would work with my dining room table so I thought it would be fun to make one out of 3/4" MDF. I had all my pieces cut at the hardware store so all I had to do was put the pieces together.
I used 1 x 4'x8' sheet of 3/4" MDF because I needed the rest of the MDF for another project but you can fit the pieces for the bench in 2 x 2'x4' sheets ($25) and the lattice was about $5 so that's $30 for the materials. I already had the primer, paint, and screws on hand.
I'll outline the main steps here but you can also see the entire building process in detail in this video:
Step 1: Attach the legs to the top
I put glue on the top edge of the leg and used corner clamps to hold it to the top. I drilled pilot holes to prevent splitting and screwed the pieces together, sinking the screw heads below the surface.
Step 2: Screwing in place the back piece
I screwed in place the back piece flush with the top and the legs, following the same steps as for the legs.
Step 3: Attach the front piece
To have more support at the front of the bench, I glued together 2 MDF pieces to make one thicker piece, using clamps to make sure they bonded very well together. I wanted the front piece to be recessed by about 1 inch so I used a combination square to mark the location of the front piece on the inside of the legs, making it easy to slide front piece in the right spot. I added glue to the edge and clamped it. I screwed it into place from the top and the side, making sure to avoid the screw that was already there from joining the top to the legs.
