Product Description

The YUXIANG MB-MESH-01 mid-back ergonomic mesh swivel office chair presents a streamlined, professional profile finished in a cohesive matte black palette, with balanced component proportions suited to unobtrusive placement across varied work environments. Its structure centers on a contoured mid-rise backrest paired with a generously sized seat, fixed curved loop armrests positioned to support natural forearm alignment, and a wide five-star base fitted with dual-wheel casters for stable, agile movement. Constructed for consistent long-term use, the chair’s backrest uses breathable black polyester mesh stretched over a glass-fiber reinforced nylon frame, anchored by an integrated curved structural lumbar brace to support the lower back during extended seated periods. The seat is built on a 12mm thick plywood support board, padded with 50mm thick high-density molded polyurethane foam and upholstered in durable black woven fabric. Fixed armrests are formed from robust polypropylene, while core functional components include a Class 3 carbon steel gas lift cylinder, 2.0mm thick cold-rolled steel mechanism plate, and injection-molded black nylon five-star base. The backrest mesh delivers reliable abrasion resistance, casters are engineered for extended rolling durability, and the seat cushion uses high-resilience 45 kg/m³ density foam for balanced comfort. Functional features are tailored to flexible seated work needs: a 100mm pneumatic seat height adjustment is operated via an intuitive under-seat lever, the chair supports full 360-degree swivel, and a 15-degree rocking recline is paired with a user-adjustable under-seat tension knob to customize recline resistance to individual preference. Five dual-wheel casters enable smooth, quiet movement across common floor surfaces, while fixed armrests provide consistent upper body support during typing or writing tasks. This chair is well suited for a wide range of commercial and residential spaces, including open office cubicles, individual corporate workstations, residential home studies and remote work setups, conference and boardroom areas, student study desks, front reception and visitor waiting zones, and flexible training or seminar rooms. Procurement teams should note that each unit ships across two cartons, with a 40-minute per-unit assembly time, and plan for appropriate receiving and assembly staffing when ordering for large-scale deployments. Buyers should also align selection with the recommended user weight limit to ensure optimal product service life, and account for packaged weight and volume when coordinating freight and on-site storage.
