A vehicle seat for automatic inclination compensation, comprising a seat part and a backrest,
- wherein a fluid chamber unit with at least two flexibly designed fluid chambers is arranged between at least one seat plate part of the seat part and a there-above arranged seat cushion part of the seat part,
- wherein in relation to a center axis extending in the sitting direction, a first half of the fluid chambers are arranged on a left side and a second half of the fluid chambers are arranged on a right side of the center axis,
- wherein the first and second halves of the fluid chambers can be filled or emptied by means of a control device in dependence on a detected lateral inclined position of the seat part in such a way that a seat user automatically experiences a compensatory position in relation to the inclined position in the seat part independently of a backrest position,
- wherein at least one first plate element is arranged on the left side and at least one second plate element is arranged on the right side between the fluid chambers and the seat cushion part arranged thereabove, in order to obtain a more stable supporting seat surface for the seat user, and
- wherein the at least one first and second plate elements each have a left-hand and a right-hand surface extension with respect to the center axis, which is not smaller than the surface extension of the fluid chambers arranged below and on the left-hand or right-hand side.
