PROBLEM TO BE SOLVED: To provide a laminated foam excellent in body pressure dispersibility, and its manufacturing method. SOLUTION: The laminated foam has a highly resilient foamed part 2, which comprises resin foam (e.g., polyurethane foam or the like) and has a peak/valley surface (e.g., profile processed surface or the like) 21 and the low resilient foamed part 3 closely bonded to the peak/valley surface 21 of the highly resilient foamed part 2 and comprising polyurethane foam with a repulsive elasticity modulus of 10% or below. The method for manufacturing the laminated foam comprises a foam arranging process for arranging a highly resilient foam having the peak/valley surface to a mold, a raw material charging process for charging a polyurethane foam raw material in the mold and a low resilient foam forming process for foaming the polyurethane foam raw material to form the low resilient foam comprising polyurethane foam with the repulsive elasticity modulus of 10% or below on the peak/valley surface of the highly resilient foam.
