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.

1. A method for manufacturing a layered support structure, comprising: providing a first layer comprising: a support rail comprising: a first strap comprising multiple pre-alignment regions and unaligned regions defined along the first strap;a second strap substantially parallel to the first strap and comprising multiple pre-aligned regions and unaligned regions defined along the second strap;multiple nodes connected between the first and second straps; andmultiple openings defined along the support rail between an inside edge of adjacent nodes, an inside edge of the first strap, and an inside edge of the second strap, where the inside edges of adjacent nodes substantially face each other and the inside edges of the first and second straps substantially face each other;providing a second layer comprising multiple spring elements supported by the nodes; andconnecting the second layer to the first layer, where the second layer is positioned below the first layer after the connecting. 2. The method of claim 1, where the first layer is provided using an injection molding technique. 3. The method of claim 1, where the first layer is provided using a center gated injection molding technique. 4. The method of claim 1, further comprising aligning each of the multiple pre-alignment regions of the first and second straps to form multiple aligned regions defined along the first strap and the second strap. 5. The method of claim 4, where aligning each of the pre-alignment regions comprises: stretching the first layer in a direction substantially parallel to the direction of the first and second straps; andinserting a node locator into each of the multiple openings. 6. The method of claim 5, where the first layer is stretched approximately 10-12 inches. 7. The method of claim 5, where the stretching causes each of the multiple pre-alignment regions to be stretched approximately four to eight times a pre-alignment length. 8. The method of claim 1, further comprising: providing a third layer comprising multiple interconnected pixels supported by the second layer. 9. The method of claim 8, where the second and third layers are provided using an injection molding technique. 10. The method of claim 8, further comprising: connecting the third layer to the second layer, where the third layer is positioned below the second layer after the connecting. 11. A method for manufacturing a layered support structure, comprising: providing a first layer comprising: a support rail comprising: a first strap comprising multiple pre-alignment regions and unaligned regions defined along the first strap;a second strap substantially parallel to the first strap and comprising multiple pre-aligned regions and unaligned regions defined along the second strap;multiple nodes connected between the first and second straps; andmultiple openings defined along the support rail between an inside edge of adjacent nodes, an inside edge of the first strap, and an inside edge of the second strap, where the inside edges of adjacent nodes substantially face each other and the inside edges of the first and second straps substantially face each other;aligning each of the multiple pre-alignment regions of the first and second straps to form multiple aligned regions defined along the first strap and the second strap;stretching the first layer in a direction substantially parallel to the direction of the first and second straps; andinserting a node locator into each of the multiple openings. 12. The method of claim 11, where the first layer is stretched approximately 10-12 inches. 13. The method of claim 11, where the stretching causes each of the multiple pre-alignment regions to be stretched approximately four to eight times a pre-alignment length. 14. The method of claim 11, where the first layer is provided using an injection molding technique. 15. The method of claim 11, further comprising: providing a second layer comprising multiple spring elements supported by the nodes; andconnecting the second layer to the first layer, where the second layer is positioned below the first layer after the connecting. 16. A method for manufacturing a layered support structure, comprising: providing a first layer comprising: a support rail comprising: a first strap comprising multiple pre-alignment regions and unaligned regions defined along the first strap;a second strap substantially parallel to the first strap and comprising multiple pre-aligned regions and unaligned regions defined along the second strap;multiple nodes connected between the first and second straps; andmultiple openings defined along the support rail between an inside edge of adjacent nodes, an inside edge of the first strap, and an inside edge of the second strap, where the inside edges of adjacent nodes substantially face each other and the inside edges of the first and second straps substantially face each other;providing a second layer comprising multiples spring elements supported by the multiple nodes;providing a third layer comprising multiple interconnected pixels supported by the second layer;connecting the second layer to the first layer, where the second layer is positioned below the first layer after the connecting; andconnecting the third layer to the second layer, where the third layer is positioned below the second layer after the connecting. 17. The method of claim 16, where the first layer is provided using an injection molding technique. 18. The method of claim 17, wherein the first layer is provided using a center gated injection molding technique. 19. The method of claim 16, further comprising aligning each of the multiple pre-alignment regions of the first and second straps to form multiple aligned regions defined along the first strap and the second strap, wherein the aligned regions comprise aligned material that is one of a compression aligned polymer material or a tension aligned polymer material. 20. The method of claim 16, where the second and third layers are provided using an injection molding technique.
