Viscoelastic polyurethane foam with coating

A coated viscoelastic polyurethane foam, comprising:

• a viscoelastic polyurethane foam that is a product of a reaction system having an isocyanate component that includes at least one isocyanate and an isocyanate-reactive component that includes a polyol component, and the isocyanate index of the reaction system being from 50 to 150, wherein the polyol component includes a blend of at least three polyols, the blend including:
• (i) a polyoxyethylene-polyoxypropylene polyether polyol that has an ethylene oxide content of at least 50 wt %, has a nominal hydroxyl functionality from 2 to 4, has a number average molecular weight from 700 g/mol to 1500 g/mol, and accounts for 25 wt % to 90 wt % of the isocyanate-reactive component,
• (ii) a polyoxypropylene-polyoxyethylene polyether polyol that has an ethylene oxide content of less than 20 wt %, has a nominal hydroxyl functionality from 2 to 4, has a number average molecular weight greater than 1500 g/mol and less than 6000 g/mol, and accounts for 5 wt % to 50 wt % of the isocyanate-reactive component, and
• (iii) a polyoxypropylene polyether polyol that has a nominal hydroxyl functionality from 2 to 4, has a number average molecular weight from 700 g/mol to 1500 g/mol, and accounts for 5 wt % to 50 wt % of the isocyanate-reactive component;
• a coating material on and embedded within the viscoelastic polyurethane foam, the coating material including one or more aqueous polymer emulsions and one or more preformed encapsulated phase change materials;
• and
• wherein the one or more aqueous polymer emulsions comprises, as copolymerized units, from 0.3% to 2.5% by weight, based on dry polymer weight, (meth)acrylic acid.
