Ergonomic Mesh Office Chair with Adjustable Lumbar Support

Description

This black mesh office chair features 3D adjustable armrests (height, fore-aft, and angle adjustable) and a 3D adjustable headrest to meet precise posture adjustments. The lumbar support can move up and down to conform to the curve of the lumbar spine. The seat cushion uses a composite structure of breathable mesh fabric and high-elastic sponge, approximately 53cm wide and 50cm deep, providing excellent support. The core height adjustment component uses an SGS Level 4 gas spring, which has undergone cycle life and impact testing, ensuring smooth and reliable rotation and height adjustment. The chair legs are made of thickened nylon material and equipped with silent, non-slip casters, preventing damage to the floor during movement. The overall dimensions are 115-130cm high, with a backrest height of approximately 58cm. The product uses a modular manufacturing process, with precise fit at all interfaces, resulting in a robust structure suitable for home office, administrative, and other daily use scenarios.
