Abstract: A polyurethane foam for comfort application, includes the reaction product of a first composition that includes from 20 wt % to 80 wt % of an aqueous component and from 20 wt % to 80 wt % of a hydrophilic isocyanate-terminated prepolymer component. The aqueous component includes at least 90 wt % of water based on the total weight of the aqueous component and the hydrophilic isocyanate-terminated prepolymer component has a free NCO content from 1 wt % to 15 wt % and is a reaction product of a second composition that includes an isocyanate component and an isocyanate-reactive component. The isocyanate component includes at least 90 wt % of methylenediphenyl diisocyanate (MDI) and a weight ratio of 4,4′-methylene diphenylisocyanate isomer to 2,4′-methylene diphenylisocyanate isomer greater than 1:1 and less than 10:1, the isocyanate-reactive component including polyethylene glycol and a polyoxypropylene-polyoxyethylene polyol having a molecular weight of from 3000 g/mole to 7500 g/mole and a polyoxyethylene content of at least 50 wt %, and the hydrophilic isocyanate terminated prepolymer component having an polyoxyethylene content from 45 wt % to 75 wt %, based on the total weight of the second composition.
