It introduces the innovative dynamic adaptive lumbar support mechanism, supporting 6D automatic deformation movement to provide comprehensive lumbar support tailored to various body shapes.

The precise elasticity adjustment system allows users to tailor the chair to their weight for optimal softness and elasticity, alleviating back pressure and creating a sensation of weightlessness.
