The Black Mesh Back Task Office Chair with Fixed Arms (model OC-MESH-BK-001) is an unbranded entry-level office task chair designed for balanced functionality and understated visual appeal. It features a uniform black aesthetic across its entire structure, with a mid-back mesh panel set within a hard plastic frame, a fabric-upholstered padded seat, fixed one-piece plastic armrests with an open rectangular side profile, and a 5-point base fitted with twin-wheel casters. Its streamlined form fits seamlessly into spaces requiring consistent, unobtrusive seating arrangements. Construction of the chair combines durable, practical materials tailored to regular office use. The backrest uses a tensioned woven black mesh with a breathable grid structure, supported by an injection-molded black hard plastic frame and an internal reinforced bent plywood or composite frame. The seat holds a foam-padded core wrapped in solid black fabric, with an internal plywood or steel support frame for structural stability. Fixed hard plastic armrests mount rigidly to the seat frame, while a steel gas lift cylinder with a black outer casing connects the seat assembly to the 5-star base, which has a metal inner structure and matte black outer finish. Five twin-wheel casters complete the mobility system, with steel and cold-rolled steel forming the core of the tilt mechanism. The chair delivers core task seating functions for daily use. Pneumatic seat height adjustment is controlled via a right-side lever, with a maximum seat height of 500 mm above the floor. It offers 360-degree continuous swivel rotation and a knee-tilt recline mechanism with lever-activated lock, supporting 12 degrees of backward tilt from the upright position. The fixed armrests provide rigid vertical support, while the tensioned mesh back delivers passive ventilation and flexing lumbar support without active lumbar adjustment. Five twin-wheel casters enable smooth rolling on hard flooring and low-pile carpet, paired with the wide 5-star base for steady anti-tip performance. This chair is suited for a wide range of commercial and residential settings. It works well in general office workstations, including open-plan layouts and individual offices with standard 760 mm height desks, supporting 8-hour daily seated computer work for staff, administrative, and clerical users. It is appropriate for meeting rooms, training areas, co-working spaces, temporary project workstations, and hot-desking environments, where its uniform appearance, easy maneuverability, and low maintenance requirements support flexible, high-usage operations. For residential use, it fits standard home office desk setups, with a compact footprint and straightforward assembly accessible to end users. It is also well-suited for bulk procurement by small and medium enterprises seeking unified office furniture with balanced cost performance. For procurement planning, the chair supports a maximum user weight of 120 kg, with a net weight of 12 kg for freight calculation purposes. It ships in a knock-down configuration, with one unit per primary carton for standard flat packing. Assembly time aligns with typical task chair self-installation timelines for end users. When evaluating supplier quotes, buyers should confirm exact material specifications, component grade details, and certified performance ratings to align with specific project durability and compliance requirements.
