This is a pattern for camp benches that I made.

Some people take expensive antique reproductions camping in the mud and rain. Frankly, I think that's a bad idea. As with the table, chest, and chair patterns in this section, the goal for these benches was to make the most of a single sheet of plywood while presenting an historic silhouette. They also come apart and lie flat on the floor of your cargo vehicle.
This pattern gives two sturdy benches from a sheet of 1/2" plywood. They took an hour or so to cut out, plus some time to stain.
