Product Description

The unbranded Mid-Back Mesh Swivel Office Task Chair, model OFCH-MESH-064, presents a streamlined, functional silhouette designed for versatile workplace and home use. It features a neutral black finish that blends seamlessly with standard commercial and residential decor, with a compact 640 x 640 mm footprint that fits neatly under work surfaces without excess visual bulk. Its mid-height back is framed in reinforced polypropylene, with a tensioned breathable polyester mesh center that curves to form a static lumbar support zone, paired with a fabric-upholstered seat finished with a rounded waterfall front edge. Fixed hard polypropylene armrests sit 190mm above the seat surface, topped with flat padding, and the chair rests on a five-star base fitted with dual-wheel casters for unobtrusive, stable support. Durable, purpose-built materials form the chair’s core structure. The 90mm thick seat cushion uses 45kg/m³ density high-resilience polyurethane foam wrapped in wear-resistant polyester fabric, while the 70mm thick back section relies on flexible mesh for constant air circulation. The frame uses reinforced plastic, paired with a Class 3 carbon steel gas lift, a 2.5mm thick stamped steel tilt chassis, and a glass-fiber reinforced nylon five-star base with 2.5mm wall thickness. It rolls on 50mm diameter polyurethane casters, with all structural components covered by a 3-year warranty. The chair supports a maximum static user weight of 120 kg, with a 95 kg seat dynamic load rating, and casters rated for 40,000 rolling cycles. Key practical functions support daily seated use: pneumatic seat height adjustment delivers 100mm of travel via a right-side under-seat lever, locking at any position across its range, while full 360-degree swivel allows easy multi-directional access to desk surfaces. The backrest offers a synchronized 12-degree backward tilt with adjustable tension, and the casters move smoothly across hard floors and low-pile carpet. The contoured lower back frame delivers consistent static lumbar contact, and the waterfall seat edge reduces thigh pressure during extended sitting sessions. This chair is suited for a range of spaces: open-plan office workstations for 8-hour daily employee use, compact home office setups for remote work and study, conference and meeting rooms for temporary seating, training facilities where easy reconfiguration is needed, and small business reception areas. It pairs optimally with desks up to 2.4m in width. For procurement, note each unit ships in 2 cartons, requires 40 minutes of assembly per set, and 135 sets fit in a 20GP container at 85% space utilization, with a packaged gross weight of 23 kg per set.
