产品描述

The Black Mesh High-Back Swivel Task Chair with Headrest and Fixed Arms, model UBC-MHB-620-FA, offers a professional all-black seating solution for offices and home workspaces. Its tall mesh back creates a streamlined visual profile, while the padded headrest, contoured fabric seat, angular fixed arms, and five-star caster base provide a balanced task-chair layout. The clear width between armrests is 540 mm, and the high-back structure is suited to users who want shoulder, upper-back, and head support during computer-based work. Construction combines flexible and supportive materials. The back uses black flexible polyester mesh within an injection-molded polymer frame, with three horizontal lumbar bands that distribute back pressure without a separate adjustable pad. The seat is upholstered in black woven polyester fabric over molded polyurethane foam; the cushion core is 48 kg/m3 foam and 70 mm thick at the center, with a finished cushion thickness of 90 mm. A molded plywood or reinforced polymer carrier supports the seat from below. The headrest has a black mesh-faced padded contact surface and polymer shell, while the armrests use molded polyurethane or polymer pads on angular support posts. Functional details support varied working postures. A 50 mm black steel telescoping gas lift provides 100 mm of seat-height travel through a right-side paddle lever. The powder-coated steel center-tilt mechanism lets the seat and back recline together through 15 degrees, with an upright lock for focused keyboard work and a rear-facing knob offering tension adjustment across five turns. The headrest adjusts through 60 mm of vertical travel and 15 degrees of angular tilt. Fixed-height armrests deliver 230 mm of forearm support without pivot or slide movement, and polyurethane twin-wheel casters provide mobility on the nylon five-star base. The chair is appropriate for open-plan workstations, private offices, home offices, meeting and training rooms, hot-desk settings, and hard-floor or low-pile carpet areas. Its swivel access, black appearance, and adjustable features fit rotating users and standard desks. Procurement teams should note the unbranded product identity, 16 kg net weight, 130 kg recommended user weight, and 185 cm suitable user height. Each set ships in two cartons with a packaged gross weight of 23 kg, and assembly time is referenced at 40 minutes per set. These logistics and feature points should be reviewed alongside local seating standards and project volume needs.
