Kadyn - High Back Ergonomic Office Chair, 4D Armrests & 120° Recline, Breathable Mesh, 360° Swivel - Black

SIHOO Doro-S300 New Version Ergonomic Office Chair-SIHOO Design Zero-Gravity Mechanism and Mesh Cushion As a groundbreaking new product from the SIHOO brand, the S300 features unprecedented design and ergonomic structure. It introduces the innovative dynamic adaptive lumbar support mechanism, supporting 6D automatic deformation movement to provide comprehensive lumbar support tailored to various body shapes. With its four-bar linkage mechanism, the chair adjusts with the changing angle of the body's center of gravity during reclining, capturing the sitting posture and ensuring the seat cushion and backrest consistently conform to the curvature of the spine, dynamically distributing body pressure from the hips and back onto the chair. Regardless of the sitting position, the body experiences relaxation, alleviating fatigue from prolonged sitting and safeguarding spinal health. The precise elasticity adjustment system allows users to tailor the chair to their weight for optimal softness and elasticity, alleviating back pressure and creating a sensation of weightlessness. Equipped with large-edge silent PU wheels (electroplated center cap), the chair moves quietly and smoothly without damaging floors. The chair has passed rigorous SGS and BIFMA tests for quality assurance. Additionally, it comes with 24/7 online customer service and a 3-year warranty.
