According to the present invention, in a plan view of a seat surface (10a), a plane area of a part surrounded by an inner edge (17a) of a rear part (17) in a left-right direction (X) and a contour (L) is larger than a plane area of a part sandwiched by an inner edge (18a) of a front part (18) in the left-right direction (X) and the contour (L) in the left-right direction (X). In addition, a part of a pair of left and right second synthetic resin materials forming a lower part having a maximum gap therebetween in the left-right direction (X) is positioned in a thigh rest part (14) and a part having a minimum gap is positioned in a hip rest part (15), and a maximum value (W1) of the gap between the pair of left and right second synthetic resin materials forming the lower part in the left-right direction (X) is two times or more a minimum value (W2) of the gap in the left-right direction (X).

An apparatus and method are provided for a sofa seat cushion comprising a cushion core including a multiplicity of pocketed springs enclosed within an upholstery foam envelope. The pocketed springs are positioned side by side in a spring layer arrangement and are independently operable. A memory foam layer positioned above the upholstery foam envelope comprises a material capable of molding to a person's body sitting on the sofa seat cushion and then quickly returning to an original shape once the person leaves the sofa seat cushion. The memory foam layer comprises a gel-infused visco-elastic memory foam with a polyethylene terephthalate layer positioned there above. Directly below the upholstery foam envelope is an upholstery-grade polyurethane foam layer with a polyethylene terephthalate layer positioned directly thereunder. An exterior upholstery surrounding the cushion core provides a plush seating surface.

A seat pad manufacturing method is provided. The method includes disposing a sheet member inside a foaming mold for shaping a seat pad, then injecting a foaming resin material into the foaming mold and foaming a resin foamed body through mold clamping, and demolding the resin foamed body in a state in which the sheet member is buried in the resin foamed body. Both end parts of the sheet member in the right-left direction and both end parts of the sheet member in the extending direction are each temporarily fastened to the surface of the mold through a fastener. The foaming resin material is injected into a space between the mold surface and the sheet member. A central part of the sheet member deforms into a shape curved in a convex shape as the sheet member is pressed upward through expansion of the foaming resin material.
