A seat with an adjusting mechanism for selectively changing a contour and firmness of the seat. A force/pressure sensor is arranged between the contour of the seat which is in contact with the occupant, and the adjusting mechanism. The force/pressure sensor measures the actual force/pressure with which the occupant presses upon the seat, and which force/pressure is adjustable by the respective adjusting mechanism. A control unit stores a desired force/pressure value for the seat, and controls the adjusting mechanism to drive the actual force/pressure towards the desired force/pressure. The seat also has an operator interface which receives input from an operator. The control unit has a manual mode where the adjusting mechanism is only controlled by the operator interface. The control unit in the automatic mode records the actual value from the force/pressure sensor when the operator adjusts the seat through the interface. The control unit then sets the desired force/pressure to the present value of the force/pressure sensor. Once the operator is finished changing the adjusting mechanism, the control unit continues in automatic mode and performs any changes to the adjusting mechanism to drive the actual force/pressure from the force/pressure sensor for the value of the new desired force/pressure.
