A cushioning for a seat part and/or a backrest of a vehicle seat, having a ventilation layer through which air can flow and which comprises an air-permeable and water-permeable top and bottom layer. Elastically bendable, mutually spaced spacing webs or threads hold these layers at a distance and connect them with one another. Fans or ventilators blow air into the ventilation layer. For ensuring an intensive ventilation of the entire cushioning surface of the vehicle seat provided for the seat user, specifically also when the fan outputs available for the ventilation are limited, the density of the spacing webs or threads is selected to be larger in the longitudinal direction of the cushioning than in the width direction of the cushioning. Thereby, the air is distributed over the entire seat width and backrest width before flowing widely in the longitudinal direction of the seat part or of the backrest along under the cushioning surface.
