Family-owned, fifth-generation manufacturer Irwin Seating Co., headquartered in Grand Rapids, Mich. has been thinking about the comfort and functionality of the public seating it has manufactured for more than 100 years. The company's 35 presses are used to stamp the components that support the seats, mount them to the floor, and attach them to the backs; as well as pivots, brackets, and other internal mechanisms.
