Patent ID: 8901189

Claim:
An open cell, polyurethane foam material comprising the reaction product of: a base polyol including a petroleum-based polyol and a plant oil-based polyol, wherein the plant oil-based polyol is present in the base polyol in an amount between 5 and 30 parts per hundred polyol, wherein the base polyol has a functionality of 2.3 to 2.9; an isocyanate; water; a surfactant; and a crosslinker, wherein greater than 5 percent of the content of the foam material is from non-petroleum based content, wherein the foam material is molded for use as a vehicle seat cushion and has a natural frequency of less than about 4.6 hertz and a transmissivity of about 3.6 or less when the foam material has a thickness of approximately 100 mm, and wherein the foam material has a comfort number less than 12.7 as determined by the product of the natural frequency and a peak transmissibility of the foam material.
