Abstract: Recovery time and/or airflow of flexible polyurethane foam is increased by including certain tackifiers in the foam formulation. The tackifiers are characterized in being incompatible with polyol or polyol mixture used to make the foam, having a viscosity of at least 10,000 centipoise at 25° C., having a glass transition temperature of at most 15° C. and being inert to other components of the foam formulation.
