Abstract
A foam article for use in a seat cushion includes an open cell, polyurethane foam material that includes a base polyol; a crosslinker; an isocyanate; a surfactant; and water, that are reacted together to produce a seat cushion having dynamic and static performance specifications that are better than the performance characteristics for a traditional, high resilient material seat cushion, as well as other seating materials.
