The circuit arrangement includes at least one driver unit with at least one driver to activate the actuator with the at least one SMA element; at least one temperature sensor; and a control unit to control the driver unit, the control unit being configured to generate a control signal to control the driver unit. The control signal is determined from a) at least one actual filling level parameter; b) a temperature signal from the temperature sensor; c) a system parameter; and d) at least one of a target filling level parameter and a target filling level change parameter. A related seat and method of controlling same are also disclosed.",
