The Light Grey Split-Back Ergonomic Office Task Chair, model OF-SB-680-GY, features a clean, understated aesthetic anchored by a coordinated light grey and white neutral color palette. Its signature split-back design uses dual separate upper back panels paired with a dedicated curved lower lumbar pad, framed by fixed loop armrests and a matching five-star base fitted with rolling casters, creating a streamlined silhouette that blends seamlessly with contemporary interior schemes. Constructed for consistent long-term use, the chair’s seat and back are upholstered in durable light grey woven polyester fabric, padded with CFC-free high-density polyurethane injection foam for the seat and molded high-resilience polyurethane foam for the back and lumbar support. Its structural components include a glass-fiber reinforced PA/PP back frame and armrests, a multi-layer pressed wood composite seat support plate, a powder-coated A3 steel tilt mechanism, a chrome-plated Class 3 gas lift, a glass-fiber reinforced nylon five-star base, and dual-wheel PU casters for smooth floor movement. Functional features are tailored to support extended seated comfort: pneumatic seat height adjustment controlled by a right-side lever delivers flexible positioning to align with varying desk heights, while a central swivel joint enables full 360-degree horizontal rotation. The backrest offers a synchronized free-float rocking tilt with an under-seat tension adjustment knob, plus three lockable positions to secure preferred back angles, with a maximum recline of 15 degrees from upright. The split back structure works to reduce spinal pressure during seated tasks, while the fixed lumbar pad delivers consistent mid-lower back support. This chair suits a wide range of both commercial and residential settings. It is designed for 8-hour daily use at standard-height workstations in open-plan offices, fits compact home workspaces for remote work and study, supports collaborative movement in meeting rooms and co-working shared spaces, offers adjustable height to suit teen and adult users at student study desks, and presents a professional, unobtrusive look for reception and administrative workstations. For procurement planning, note that each unit ships in two cartons and requires 40 minutes of assembly time. The neutral finish coordinates with a broad range of modern workspace decor palettes, and the chair supports a maximum recommended user weight of 150 kg, making it accessible for a wide base of users across shared and dedicated seating applications. Its compact footprint makes it easy to deploy in both spacious open offices and smaller enclosed work zones without disrupting traffic flow.
