2.1. Ergonomic Design
The chair incorporates an innovative ergonomic design with biomimetic curves that separate the chair back into scientifically divided zones. These zones provide targeted support for the neck, spine, and lower back, promoting spinal health. The lumbar support is designed to conform closely to the lumbar spine, preventing suspension and ensuring a snug fit.

Both the seat and backrest are constructed with advanced HD dragon-scale mesh material. This mesh is wear-resistant, non-slip, and highly elastic, providing a refreshing and breathable experience. The ergonomic curved surface of the seat cushion is designed to reduce pressure on the legs, ensuring comfort even during prolonged use.
