Product Description

The Black Mesh Ergonomic Office Chair with Headrest is an unbranded high-back task chair designed for supported seated work. Model ERG-MESH-HR-BK-01 presents a coordinated black appearance, with a flexible mesh back and headrest, fabric-upholstered foam seat, black polymer armrests and frame, and a nylon five-star base. Its dual-wheel casters and central steel gas lift complete the mobile executive-task form. The back is framed in polymer and uses an integrated lumbar curve, while a raised padded lumbar pad sits behind the lower mesh zone. The curved headrest has a breathable mesh face, padded perimeter, and black polymer support housing. Flat polymer arm pads mount on injection-molded posts, leaving a clear width of 540 mm between armrests. The seat cushion is 90 mm thick and upholstered in black woven fabric over molded 45 kg/m3 high-resilience polyurethane on a load-bearing seat pan. Backrest padding is 70 mm thick, and the lumbar support zone is 240 mm high. Internal structure includes a 2.0 mm steel seat plate and tubular steel back brackets with black powder coating. Functional adjustment is centered on the pneumatic seat-height lift, which moves through a 100 mm stroke from 450 to 550 mm. A synchro-tilt mechanism allows an 18-degree back recline, with lock positions at 94, 102, and 110 degrees. A rear under-seat rotary knob controls recline resistance for users up to the recommended capacity of 136 kg. The headrest adjusts 160 mm vertically and pivots 25 degrees to provide neck support. Listed material and component targets include 1200 N warp and 1000 N weft back mesh tensile acceptance without seam or frame failure, 50,000 Martindale abrasion cycles for the seat textile, 100,000 caster rolling cycles on hard commercial flooring, and 100,000 gas-lift height-adjustment cycles. The base has a static vertical load reference of 680 kg, equal to 5.0 times the recommended user load. The chair is suited to desk-based employees in open offices and private workstations where high-back, headrest, and lumbar support are needed for 8-hour seated tasks. It is also appropriate for home offices and study settings, offering a 670 mm footprint, swivel mobility, and adjustable height for use with a standard 760 mm desk. Procurement planning should note delivery as one set across two cartons, with 720 x 640 x 360 mm and 850 x 420 x 720 mm carton dimensions, a packaged gross weight of 23 kg per set, total carton volume of 0.26 m3 per set, and a reference assembly time of 40 minutes per set.
