Product features

1. Ergonomic Design: The SIHOO ergonomic chair incorporates all the key features of ergonomic design. Its S-shaped backrest follows the natural curve of the human spine, providing full support for the back. The adjustable headrest supports the neck, offering health-conscious users long-lasting comfort and optimal support. The chair can be easily tilted to 110°, 116°, or 126°, and its height can be adjusted by up to 10 cm, helping you find a comfortable position during long gaming sessions or while working.
2. 3D Armrest: Unlike 2D armrests, 3D armrests can be raised and lowered across 5 positions. The PU leather armrest surface can also be adjusted forward and backward, as well as rotated left and right to adapt to changes in your sitting posture. This provides multi-angle support for your hands, allowing you to maintain a healthy and comfortable posture whether you are gaming, streaming, working, or taking a nap.
3. Mesh Material: The springy foam at the front of the seat cushion, combined with its curved design, provides ample support while you sit. The seat and backrest are constructed from polyester mesh, which is both durable and breathable. This material offers reliable support while helping you stay cool and sweat-free on hot summer days.
4. High Quality & Easy Assembly: This computer office chair features components that have all passed rigorous safety and quality inspections, including cushion impact tests, armrest fatigue tests, and static pressure tests on the chair base. The gas lift of this high-back office chair is BIFMA and SGS certified and supports up to 330 lbs (23.57 st) in weight.
