A method for producing automotive seat covers from trilaminate foams has been developed by Magna International of Aurora, Ontario, Canada. According to the company, seats with concavities of over 10 cm in depth can be produced using the technology (FreeForm), which is impossible when using cut-and-sew techniques for producing seat covers. Further, design features with radii as small as 3-4 mm (rather than the conventional limit of 20-25 mm) can be produced on seat covers and the method can be applied to any textile, leather or polymer surface specified by carmakers.
