1. A method of manufacturing a seat cushion for a vehicle seat assembly, the seat cushion having side edges and top and bottom edges, the method comprising:
- providing an outer material to define a surface that faces a seat occupant;
sewing a backing material to the outer material using a linear first longitudinally oriented sewing line;
placing a first wadding material adjacent to the linear first longitudinally oriented sewing line in a centrally located region of the backing material;
sewing the backing material to the outer material using a linear second longitudinally oriented sewing line so that the first wadding material is secured between the linear first and second sewing lines, the first and second linear longitudinally oriented sewing lines defining therebetween a central region;
making a tiered sewing line confined to the central region between the linear first and second sewing lines, the tiered sewing line running between the top and bottom edges;
disposing a second wadding material between the outer and backing materials and between the linear first sewing line and an edge of the seat cushion;
disposing a third wadding material between the outer and backing materials and between the linear second sewing line and an opposite edge of the seat cushion;
sewing along the side, top and bottom edges of the seat cushion to further secure the first and second wadding material;
making a plurality of laterally oriented sewing lines between the side edges of the seat back cushion; and
sewing the outer and backing materials together using additional sewing lines respectively disposed proximate the top and bottom edges of the seat cushion.

Abstract
A method for manufacturing a vehicle seat cushion assembly includes providing an outer material to define an outer seating surface. A backing material is sewn to the outer material using a first sewing line against which a wadding material is placed in a central region of the cushion. To secure the wadding material, a second sewing line is run. Left and right wadding materials are placed between the sewing lines and the edges of the cushion. Additional sewing lines laterally cross the longitudinal sewing lines to imbue the cushion with a wrist watch-like appearance.
