Molded flexible polyurethane foam is made from a polyol mixture that contains a dispersion of polymer particles in one or more polyether polyols of a particular type and one or more high functionality, high-ethylene oxide polyols which have an average oxyethylene content of from 26 to 100% by weight, an average hydroxyl equivalent weight of from 1400 to 2200 and an average nominal hydroxyl functionality of from 6 to 10. The polyol mixture produces a foam that has excellent resiliency and low compression sets. |
