A chair backrest, 3 braces, 2 pallet tables, and a little imagination!
For the seat, cut the 1 1/2-inch pallet boards, brush and glue, brush the assembly and give the shape of the seat.
For the legs cut the back of the chair to equal halves. Make a template to define the opening of the legs and fix with 1 1/2-inch-thick x 3/4-inch thick strips. Determine the height of the slats with respect to the floor to serve as support for the step. Present the step to fix all joints and glue with screws.
