Product Description

The Black High-Back Mesh Ergonomic Office Chair with Headrest and Adjustable Arms is a structured task seating solution designed for daily desk use. Model EM-HB-MESH-01 is supplied without a brand label and presents a clean, neutral black appearance suited to professional and residential interiors. Its tall back, contoured headrest, padded seat, and five-star caster base create a conventional ergonomic silhouette, while the high-back layout provides support from the lumbar region through the upper back and head. The chair measures 680 by 680 by 1290 millimeters overall, with a 540-millimeter clear width between the armrests. Its 90-millimeter molded foam seat cushion and 70-millimeter backrest padding contribute to a substantial seated profile, while the 240-millimeter lumbar support zone targets the lower back. Construction combines breathable black woven mesh, a rigid polymer back frame, a steel-tube and steel-plate internal frame, polymer load-bearing housings, and a steel-reinforced seat pan. The backrest uses flexible mesh kept under tension over the outer frame, and the seating surface uses black mesh or a mesh-faced panel over molded foam. The integrated lumbar structure is a curved polymer band with a padded black center section. The headrest is a framed black mesh pad fitted to a polymer height-adjustment bracket. Arm supports use injection-molded polymer posts with flat black polyurethane or soft-polymer pads, while the chair rests on a five-star base with twin-wheel casters for mobility. Functional adjustment is focused on fitting different users and work postures. A right-side under-seat lever controls the pneumatic seat-height lift, which offers 80 millimeters of effective travel. The synchro-tilt mechanism moves the seat and back together to a maximum back angle of 130 degrees, and a multi-position tilt lock secures selected upright or reclined working angles. A sliding seat pan adds 50 millimeters of fore-aft adjustment to support appropriate thigh depth. The published references include a recommended user weight capacity of 150 kilograms, 45 kilograms per cubic meter molded seat foam, a Class 4 gas lift with a 100-millimeter tube class, static seat proof load reference of 1000 newtons, backrest durability reference of 120,000 tilt cycles, caster rolling durability reference of 100,000 cycles, and back mesh tensile support reference of 250 newtons distributed load. This model is appropriate for open-plan office workstations, home offices, computer-based work areas, and executive workspaces where high-back support, adjustable arms, and mobile seating are required for six to eight hours of daily desk work or short reclined breaks. Buyers should plan for assembly, with a reference time of 40 minutes per set. The product is packaged as one set across two cartons, with a packaged gross weight of 23 kilograms and reference carton volume of 0.26 cubic meters per set. Procurement teams should confirm the final arm support material, seat surface configuration, local delivery terms, assembly responsibilities, and maintenance or replacement arrangements before ordering in volume.
