The notch lounge consists of two vertical pieces. The shape of the vertical planes are contoured to the body. The horizontal is one form that is repeated. The variation comes from the angle of the notch connections. The angled notch allows the horizontal pieces to rest perpendicular to the body. I used 3d modeling software (Rhino) to develop the form, and figure out a repeatable module. Then I cut the pieces on a CNC router and easily locked them into place.
