Abstract

Three-dimensional unitized thermoplastic foam structures are made by thermoplastic welding of different foam components. The unitized foam structures may include a planar base to which other foam components are welded to project from the base and provide a flexible three-dimensional structure.
The thermal bonding or welding of the thermoplastic foam components creates a unitized structure which is both flexible and load bearing. For mattress and seating applications, the welded foam structures may be combined with an innerspring, and certain of the foam components of the structure may mechanically engage parts of the innerspring. The preferred foam deck has first and second panels interconnected by one or more webs. One or more foam decks may be employed. Other foam components may be attached to the foam decks or other components. The unitized foam structures can be employed as single or double-sided mattresses, seating structures or other flexible support structures.
