The invention discloses vehicle seat sponge, a manufacturing method, a module and a vehicle seat. The vehicle seat sponge comprises a main functional area, wherein a left supporting area and a right supporting area are respectively arranged on the two sides of the main functional area, the main functional area sequentially comprises a front area, a middle area and a back area from the front to the back, the density of the middle area is 60-70 gram per cubic meter, the density of the front area is 45-55 gram per cubic meter, and the density of each of the left supporting area, the right supporting area and the back area is 40-50 gram per cubic meter. The vehicle seat sponge has the characteristics of being multiple in density and hardness, the position which needs to be supported has better supporting performance, the position which needs to be soft has good buffering performance and attaching performance, when a vehicle swerves, the area with the two sides being hard can reduce horizontal accelerated speed borne by a human body, so that the hip and the thighs of the human body can lightly bear the body, the horizontal stability of the human body is guaranteed, and the comfort and the safety are good.
