PROBLEM TO BE SOLVED: To provide a polyol composition for producing soft polyurethane slab foam which has high mechanical properties (tensile strength, tear strength, and the like) and excellent durability even when converted to low density.SOLUTION: The polyol composition (A) for producing soft polyurethane slab foam comprises an alkylene oxide addition product (A1) of an active hydrogen-containing compound (H) and satisfies the following (1) to (4): (1) a ratio of primary hydroxy groups among terminal hydroxyl groups of the (A) is 8 to 80%; (2) a content of ethylene oxide units based on a weight of the (A) is 10 wt.% or less; (3) a hydroxyl value of the (A) is 20 to 290 mgKOH/g; and (4) an average number of functional groups of the (A) is 2.5 to 5.0. |
