Vehicle seat assembly having layered seating system with attachment member

A vehicle seat assembly comprising:

• a cushion composite comprising:
• a structural layer adapted to be secured to a seat frame having an upper surface;
• a cushion layer covering the upper surface and directly attached to the structural layer along a lower surface, the cushion layer having a seating surface opposite the lower surface;
• one or more first attachment members embedded either in the upper surface of the structural layer or the lower surface of the cushion layer in order to releasably attach the structural layer to the cushion layer to form the cushion composite;
• at least one second attachment member embedded in one of the structural layer, the cushion layer or the seat frame;
• and
• a trim material secured over the seating surface and secured to the cushion composite by the second attachment member and not by the first attachment member so that the trim material is easily disassembled from the cushion composite in order to separate the materials for end of life recyclability.

A vehicle seat assembly comprising:

• a seat frame adapted to mount to a vehicle;
• a structural layer mounted to the seat frame and formed of a rigid first foam material to provide support to an occupant;
• a cushion layer formed of a resilient second foam material and provided adjacent to the structural layer to provide comfort to the occupant;
• a first attachment member attached directly on an upper surface of the structural layer;
• and
• a second attachment member attached directly on a lower surface of the cushion layer;
• a trim material disposed over the cushion layer to provide a seating surface;
• and
• a third attachment member attached to one of the seat frame, the structural layer or the comfort layer,
• wherein the cushion layer is assembled to the structural layer through engagement between the first attachment member and the second attachment member to form a composite cushion body, the trim material thereby wrapped around and secured to the composite cushion body by the third attachment member and whereby the trim material is not secured by the first or second attachment member, for easy disassembly of the first foam, second foam and trim materials in order to separate the materials for end of life recyclability.
