Abstract
A system (10) for manufacturing a mattress (300) comprises multiple modules or stations (12, 132, 188, 200) used to sew together multiple components into a casing (252). A spring or other core (270) is inserted into the casing (252) before a top (274) is secured to the casing (252) to complete the mattress (300). Two or more flanges (261, 266) may be incorporated into the casing (252) for securing the core (270) inside the casing (252), The system (10) provides an operator flexibility to manufacture different types of mattress with minimal changes.
