The present invention is directed to a process for the preparation of a flexible polyurethane foam and to the polyurethane foam prepared by that process. The foam is in particular a flexible polyurethane foam which has a density of between 25 and 120 kg/m³, a resilience, measured at 20°C in accordance with ASTMD3574H, higher than 35%, and an ILD 40% hardness, measured in accordance with ISO2439B, of between 60 and 500 N. It is prepared by allowing a reaction mixture, which comprises a blowing agent, to foam. In order to influence the physical and/or thermophysiological properties of the foam, in particular the pressure distribution properties, at least one organogel material is dispersed in the reaction mixture before allowing it to foam. |
