1. A vehicle seat having a seat part extending in a vehicle length direction (X) and in a vehicle width direction (Y) and having a backrest part and a seat substructure for cushioning and/or damping at least the seat part with respect to a body of a vehicle, in which the seat substructure comprises at least one horizontal spring device having a first spring part, and a second spring part which is movable relative thereto and a deformable fluid spring element for cushioning the seat part with respect to the body in the vehicle length direction (X) and/or in the vehicle width direction (Y), the deformable fluid spring element being arranged with a first connecting region to the first spring part and a second connecting region to the second spring part, wherein the deformable fluid spring element is arranged between the first and second spring parts so as to be deformed solely by the first and second spring parts upon relative movement of the first and second spring parts relative to each other along the at least one of the vehicle length direction (X) and the vehicle width direction (Y), wherein the deformable fluid spring element is subjected to shear forces by the movement of the first and second spring parts relative to each other, and wherein the deformable spring element resists the shear forces.
