Create the base by screwing the seat slats into the chair frame boards.
Attach the front arm supports so the front of the chair is off the ground. The chair frame board will act as the other support for the chair on the ground. The seat of the chair should set at a 63 degree angle.
Attach the back supports to the chair frame boards with screws along with the horizontal back supports. Attach the vertical back slats to the frame to complete the chair.
Sand the chair to remove any rough spots and varnish or paint the chair to whatever color is desired.
