Ergonomic Design: This office chair is designed with a human-oriented ergonomic structure, offering comfortable support. The backrest with 3D lumbar support conforms to the natural curve of the lower back, taking spinal discomfort away from your body. The breathable, resilient mesh also helps maintain a relaxed posture for extended periods. Multi-Functional Office Chair with Customizable Features: This chair features a 360° swivel function and seat height adjustment ranging from 17.5 to 21.2, adapting to various individuals and occasions.

Adjustable 2D Headrest & 3D Armrest: With 3D adjustable armrests, you can adjust them in three directions: forward and back, up and down, and with 30-degree angle rotation, which helps improve your posture and reduce pressure in your shoulders and wrists. Meanwhile, the 2D headrest provides additional support and can be adjusted to accommodate different head sizes and angles, reducing strain and tension in your neck, shoulders, and arms while promoting a more ergonomic sitting position. Stable and Safe: The office chair uses an SGS-certified level 3 cylinder and a robust nylon base, which has passed BIFMA testing and can support weights of up to 300 lbs
