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:
