One-piece seat structure and cold forming processes to create seat structures

A vehicle seat assembly, comprising:

• a seat base and a seat back rotatably coupled to the seat base;
• wherein at least one of the seat base and seat back is a one-piece structure having:
• a first portion having a set of characteristics and a second portion having a set of characteristics, wherein the characteristics of the first portion differs from the characteristics of the second portion, and the one-piece seat structure is formed from a tailor welded blank using a cold-forming process, the tailor welded blank constructed from the first portion coupled to the second portion.
