A circuit arrangement for controlling a system for a seat comfort function includes at least one actuator with at least one adjusting element and at least one SMA element, wherein the adjusting element can be moved from a first position to a second position. At least one resistance measuring device measures a resistance of the at least one SMA element. At least one driver unit activates the actuator with the at least one SMA element. A control unit controls the driver unit, the driver unit being configured for processing an output signal of the resistance measuring device. The circuit arrangement is configured so that the resistance measuring device and the driver unit are alternatingly operationally connected to the SMA element. Related methods of operation and seats are disclosed.
