  • Patent number: 4755411
    Abstract: A cushion for motor vehicle seating or furniture comprises a flexible outer membrane or cover and a multi-hardness foam member, comprising foam regions of different foam hardness. The foam regions are bonded together along common boundaries and are bonded to the membrane at any boundary therewith, such bonding ocurring during formulation of the foam member and employing the materials of which the foam member is made. The method generally comprises the steps of: (a) providing a flexible membrane having a cavity therein; (b) adding to the cavity in a predetermined sequence a plurality of formulations in liquid form which, when cured, provide a foam article having foam regions of different hardness; (c) and allowing the formulations to cure, bond together at any common boundary between formulations, and bond together at any common boundary between a formulation and the membrane.
