Product Description

The Black Mesh Ergonomic Task Chair presents a practical office seating solution with a clean black finish and a structured five-star footprint. Its visual character is defined by a flexible woven mesh back set within a curved polymer frame, paired with a black fabric-upholstered foam seat. Height-adjustable armrests flank the seat, while the central gas lift connects to a painted steel base fitted with twin-wheel casters, giving the chair a familiar professional task-chair silhouette suited to both shared and individual work settings. Construction balances breathable support with durable working components. The backrest uses flexible black woven mesh over a molded polymer outer frame and includes a defined lumbar support zone. The seat features molded polyurethane foam covered in black woven fabric, with a molded plywood or polymer seat pan beneath the cushion. Arm pads are finished in matte black polymer and mounted on height-adjustable posts supported by black painted steel or reinforced nylon structures. A black steel tilt mechanism, polymer lever handles, steel gas lift, and nylon twin-wheel casters complete the functional assembly. The chair is designed for active desk use. A right-hand pneumatic lever adjusts seat height, supporting transition between different desk postures. The center-tilt mechanism allows the backrest to recline from an upright position to a relaxed working angle, with a rear knob for tilt tension and a lever to lock selected positions. The seat also swivels fully around the gas-lift center, improving reach in multitask environments, while the rolling base supports movement across typical office floors. This model is appropriate for open-plan workstations, standard desk-based computer tasks, hot-desking areas, meeting rooms, and focus rooms. Its understated black appearance coordinates with commercial office furniture, and its adjustable features make it suitable for users sharing seating across shifts or flexible workspaces. It can also serve home offices and residential study areas where task seating is required for extended work sessions. Procurement teams should note that the chair is supplied unbranded under model ET-MESH-BLK-01 and ships as one set across two cartons, with assembly required. The specification includes a recommended user weight capacity, detailed cushion and lumbar dimensions, caster durability rating, and packaged weight and volume data that can support freight and storage planning. Buyers should allocate time for on-site assembly, confirm floor surface compatibility with the casters, and evaluate the armrest spacing, seat adjustment range, and recline behavior against the intended workstation or shared seating application.
