Product Description

The YUXIANG Ergonomic High-Back Mesh Office Chair, model OF-ERG-MESH-0635, delivers balanced ergonomic support and streamlined professional styling for a range of work environments. Its visual design features a structured high-back profile with matte gray reinforced nylon five-star base, complemented by breathable black mesh backrest and neutral fabric seat upholstery that fits seamlessly with both modern commercial and residential workspaces. The layout integrates a curved, vertically adjustable headrest, fixed height-matched armrests with soft polyurethane padding, and a contoured integrated lumbar zone positioned in the lower backrest, creating a cohesive silhouette that balances comfort and understated professional appeal.
Construction prioritizes durability and long-term use: the structural frame uses glass-fiber reinforced nylon, paired with a stamped steel synchro-tilt chassis and powder-coated black steel Class 3 gas lift for core stability. The backrest is upholstered in breathable polyester elastic mesh, with a molded foam lumbar pad integrated directly into the lower mesh section, while the seat uses molded high-resilience polyurethane foam with fabric cover. Black polyurethane swivel casters mount to the five-star base, supporting smooth movement across hard floors and low-pile carpet.
Functional features are tailored for extended work sessions: pneumatic seat height adjustment operates via a right-side lever, with enough travel to align with sit-stand desk configurations. The curved headrest slides vertically to support neck positioning, while the synchro-tilt mechanism locks at three positions with a maximum 125-degree backrest recline. Full 360-degree swivel and smooth rolling casters support easy repositioning, while the fixed armrests cradle forearms during typing tasks to reduce upper body strain. The integrated lumbar zone delivers consistent lower back support suited for 8-hour daily use.
This chair fits a broad range of spaces: open-plan office workstations for general staff, home office setups with standard desk dimensions, executive private offices paired with premium desk configurations, conference rooms where flexible movement around meeting tables is needed, high-traffic co-working spaces, and setups paired with height-adjustable desks. For procurement teams, key considerations include noting that each unit ships across two cartons, with a packaged weight of 23 kg per set and reference assembly time of 40 minutes per unit. The chair supports a maximum user weight of 150 kg, with durable materials rated to withstand frequent multi-user daily use.
