The price is primarily driven by the actuator system (Electric vs. Hydraulic). Electric servo systems are generally more expensive but offer higher precision, lower noise, and easier maintenance compared to hydraulic ones. Additionally, the number of Degrees of Freedom (3DOF or 6DOF) significantly impacts cost; a 6DOF system provides more complex movements (pitch, roll, yaw, etc.) and commands a premium price. The inclusion of integrated special effects like water spray, air blast, leg ticklers, and vibration within the seat also scales the unit price.
