Lower seat assembly for a vehicle seat, including a compressible cushion, with an upper face for supporting a seat occupant, and a lower face, such that the cushion is compressed when a load is applied on the upper face by an occupant. The lower seat assembly further includes a cushion supporting element, disposed below the cushion for supporting the cushion, and at least one sensing device comprising a proximity sensor, configured to sense a distance to a proximity sensor target facing the sensor. Either the sensor or the target is fixed to the lower face of the cushion, and the other one is fixed to the cushion supporting element. The lower face bends when the cushion is compressed and generates a relative movement between the sensor and the target, and the sensing device is configured to derive a weight class of an occupant from the distance between the sensor and the target.
