Abstract
Embodiments disclosed in the detailed description include a unitary or monolithic composite or hybrid cushioning structure(s) and profile(s) comprised of a cellular thermoplastic foam and a thermoset material. The thermoset material may also be provided as cellular foam as well. In one embodiment disclosed herein, the unitary composite cushioning structure is formed from a cellular thermoplastic foam and a thermoset material. The cellular thermoplastic foam provides support characteristics to the unitary composite cushioning structure. The thermoset material provides a resilient structure with cushioning characteristics to the cushioning structure. A stratum is disposed between at least a portion of the cellular thermoplastic foam and at least a portion of the thermoset material to secure the at least a portion of the thermoset material to the at least a portion of the cellular thermoplastic foam to provide a unitary composite cushioning structure.
