Product Description

The Black Mesh Back Fixed 4-Leg Conference Office Chair (model CF-MESH-4LEG-01, unbranded) features a clean, streamlined static silhouette defined by a consistent matte black finish across all components. Its structured 4-leg base supports a contoured mid-back and proportioned seat, with fixed curved armrests that flow seamlessly between the seat and back frame to create a cohesive, professional visual profile suited to formal and casual seating environments alike.
Constructed for long-term commercial use, the chair’s frame is built from 2.0mm thick carbon steel tube finished with a matte black electrostatic powder coating, paired with a glass-fiber reinforced PP back frame. The backrest is upholstered in breathable elastic polyester office mesh, while the seat uses a 12mm thick plywood support panel layered with high-density molded PU foam, wrapped in wear-resistant black polyester fabric. Fixed integrated black PP armrests connect directly to the seat and back structure for rigid support, and non-marking black PP glides fitted to each leg prevent floor damage and reduce slippage on hard or carpeted surfaces.
Designed for stable, upright seating, the chair has no height adjustment, swivel, or tilt mechanisms, maintaining a fixed upright back angle optimized for meeting settings. The contoured mesh back delivers targeted lumbar support for short to medium duration sessions, while the thick padded seat offers consistent cushioning. A key practical feature is its vertical stacking capability, which allows up to 6 chairs to be stacked for compact, space-efficient storage. The chair supports a recommended static user weight of 136 kg, with mesh upholstery rated for 50000 Martindale double rubs to withstand frequent regular use, backed by a 5-year standard commercial warranty.
This seating solution is well suited to a wide range of commercial and residential spaces, including corporate boardrooms and conference rooms, office reception and waiting areas, training and seminar spaces, government and public service halls, co-working shared office zones, and small home offices requiring dedicated guest seating. When planning procurement, note that each unit ships across two cartons, with an assembly time of 40 minutes per chair; the fixed, non-mobile design is intended for static placement rather than flexible rolling movement, and the neutral matte black finish coordinates easily with most existing interior design palettes.
