A process for making a flexible polyurethane foam, the process comprising reacting a polyether polyol with foam-forming reactants to provide said polyurethane foam, wherein said polyether polyol comprises a latent aldehyde content of at least 50 ppm, and/or said polyether polyol is obtainable from ring-opening polymerization of alkylene oxide comprising a free aldehyde content of at least 200 ppm. Foams obtainable by the process, and uses of polyether polyols are also disclosed. |
