Tony adopts the integrated design of the backrest and armrests, which not only guarantees perfect ergonomics, but also retains the modern, simple and fashionable modeling language. The seat base has a built-in precision tray system, which can realize the simultaneous tilting of the backrest and the seat cushion at different angles, making the sitting feeling more comfortable and ergonomic. By pulling the locking wrench under the seat cushion, Tony can achieve the reclining lock function. It can be used as a momentary break from the usual sedentary state.
