A method for manufacturing a multi-layered support structure provides ergonomic, adaptable seating support. The method providing multiple cooperative layers to maximize global comfort and support while enhancing adaptation to localized variations in a load, such as in the load applied when a person sits in a chair. The cooperative layers each include elements such as pixels, springs, support rails, and other elements to provide this adaptable comfort and support. The method for manufacturing the multi-layered support structure uses aligned material to provide a flexible yet durable support structure. Accordingly, the method provides a multi-layered support structure, which provides maximum comfort for a wide range of body shapes and sizes.
