The HY-815 training chair features "pushing and stacking for storage, saving space". The restrained low-key exterior design, the extreme details and the unique style give this chair a "high-end feel". The X-shaped folding metal bracket allows for stacking and storage, forming a regular shape to save space. The double-layer structure writing board can be rotated 190°, and the armrest design is small and exquisite with a sense of lines. The double-layer mesh is tightly wrapped with the streamlined back frame, and the ergonomic saddle-shaped, highly elastic and breathable colorful seat cushion combines the artistry of the exterior with the technology of the interior to achieve the coexistence of beauty and practicality.
