GRA-S

The GRA series employs a designed seat-back linkage four-bar mechanism, where rotation of the back support component drives the seat's motion, ensuring the center of gravity consistently moves along a horizontal linear path.
It allows users to experience full-body inertia in a weightless, mechanically neutral environment, enabling completely autonomous, effortless movement.
Simultaneously, it eliminates the traditional chassis, significantly reducing costs and enhancing production efficiency.
