Lateral support: The thoughtful design of the backrest and cushion especially strengthens the sense of lateral support. It can disperse pressure and support your waist and spine, along with an adjustable headrest and waist rest. High-quality padding: This chair is filled with high-quality recycled cotton, which has a soft rebound and cannot be sunken for a long time of sitting. Safety configuration: wear-resistant PVC leather, upgraded internal steel frame structure, thickened tray, high load-bearing chair base, three-level gas rod with SGS certification, and nylon wheel certified by fatigue test can ensure your safety. Synchronous tilt: The knob under the seat is the tilting tension adjustment device. By unlocking the function and pulling the handle outward, the whole backrest and seat can tilt synchronously. 5. Fashion appearance: classic colour matching, smooth appearance, dynamic fashion, eye-catching.
