Product Description

The Black High-Back Mesh Ergonomic Office Chair with Headrest, model EOCH-MH-BLK-01, presents a professional task-seating form with a tall black mesh backrest, integrated head support, fixed armrests, and a five-star caster base. Its monochrome black finish suits coordinated office interiors, while the 660 by 660 by 1290 mm silhouette provides a structured upright profile. The 540 mm clear width between armrests supports a broad seating zone, and the 240 mm lumbar support zone is positioned within the high back to align with the lower spine. Breathable black woven mesh is tensioned within a black polymer outer frame, giving the backrest a light, open visual character while retaining a framed structure. The headrest uses a curved black mesh panel on a polymer housing with a central height connector. Seat construction centers on an 80 mm molded foam pad with 45 kg/m³ foam density, black flexible fabric or mesh facing, rounded edges, and a 12 mm molded plywood or polymer carrier beneath; the finished cushion thickness is 90 mm. Backrest padding thickness is 70 mm. Fixed-height black polymer arm pads are carried on curved polymer or nylon posts. A 2.5 mm black powder-coated steel tilt mechanism, steel gas lift, nylon five-star base, and twin-wheel casters complete the construction. The chair weighs 17.5 kg and is rated for a maximum recommended user weight of 135 kg. Daily operation is controlled by a pneumatic lever under the right side, providing a 100 mm seat-height stroke. A multi-position synchro tilt lets the backrest move from 95 to 120 degrees with selectable locking positions, supporting changes between upright task work and relaxed reclining. The seat assembly rotates 360 degrees around the gas-lift center for easy reach across a workstation, and five twin-wheel casters provide rolling mobility on office floors without visible brake levers. The chair is appropriate for open-plan workstations, private offices, home offices, meeting spaces, and supervisory seating where lumbar and head support, swivel access, and controlled recline are required. It is offered unbranded, making it suitable for projects seeking a neutral specification. Procurement planning should account for one chair supplied as one set across two cartons, with a packaged gross weight of 23 kg and total carton volume of 0.26 m³ per set. The stated assembly time is 40 minutes per set. Buyers should confirm the preferred seat facing, internal carrier type, and arm-post material where molded alternatives are listed, and review delivery access, replacement parts, assembly responsibility, and warranty terms before purchase. Published durability targets include 1020 kg static seat load, 120,000 backrest cycles, 100,000 caster rolling cycles, and minimum 150 N back mesh tensile retention.
