Abstract: A pneumatic control and measuring device and seat comfort system with such a device. The pneumatic control and measuring device includes a valve and a pressure sensor, wherein the valve includes an input channel, a pressure channel, an output channel and a sealing element switched or switchable by an actuator. The sealing element is configured to connect the input channel with the pressure channel in that a supply pressure provided in the compressed air supply channel is or can be provided at an output connection of the valve fluidically communicating with the pressure channel. A pressure sensor for capturing a pressure present at the output connection is a printed-circuit-board-integrated pressure sensor.
