Product Description

The Black Mesh High-Back Ergonomic Task Chair with Headrest, model ERC-MH-013, is an unbranded ergonomic office chair designed for focused workstation use. Its tall profile combines a black flexible mesh back, a contoured outer frame, and a curved padded headrest, giving the chair a streamlined commercial appearance while maintaining a breathable back surface. The integrated raised polymer lumbar support sits behind the lower mesh, shaping the lower-back zone without adding a separate bulky component. Fixed nylon armrests with flat padded polymer contact pads frame the seat, while the glass-filled nylon five-star base and twin-wheel casters complete the familiar swivel-task-chair layout. Construction balances comfort materials with structured support. The backrest uses black mesh tensioned within a contoured polypropylene frame, and the headrest pairs a black mesh center with polymer side supports. The seat is upholstered in black woven fabric over molded polyurethane foam, with a finished cushion thickness of 90 mm. The armrests and five-star base are made from nylon, the central lift column is black steel, and the chair moves on 60 mm twin-wheel casters. Clear width between the armrests is 540 mm, providing defined side boundaries for the seating area. Daily adjustment is handled through a right-side lever that operates the pneumatic seat-height lift, which offers 100 mm of travel. A center-tilt mechanism permits up to 18 degrees of backward recline, with tension adjustment located under the seat. The chair also rotates 360 degrees around the central gas-lift axis and rolls omnidirectionally across its five-point base, supporting normal transitions between desk tasks, nearby storage, and meeting positions. The recommended user weight capacity is 150 kg. This model is appropriate for individual office workstations where head support, lumbar support, and swivel mobility are priorities. It is suited to open-office seating plans, private offices, home offices, and meeting rooms that call for a black mesh rolling chair, particularly for desk shifts lasting 6 to 8 hours. For procurement, the neutral black finish and unbranded presentation make the chair suitable for project-based standardization. Buyers should plan for assembly, with a reference time of 40 minutes per set. Each set is supplied in two cartons, with a packaged gross weight of 23 kg and reference carton volume of 0.26 m³. Seat foam density is 45 kg/m³, and the listed component verifications include a 100,000-cycle gas-lift service rating, 100,000-cycle caster rolling durability, a 1,136 kg base static-load verification, and a 25 kg static pull per 100 mm strip for back mesh tensile verification. These details should be reviewed alongside delivery access, assembly responsibility, maintenance expectations, and the need for consistent seating across multiple workstations.
