A 4-poster or four poster is an automotive test system specifically designed for the testing of vehicles. These test systems consist of 4 hydraulic actuators on top of which the wheels of the vehicle are placed. Movements of the actuators simulate the road surface and forces exerted by the road on the wheels. The movements of the system are tightly controlled by a digital test controller. During the research phase of a vehicle, a 4-poster system is used to test newly designed suspension systems
