Product Description

The Two-Tone Grey Mid-Back Swivel Height-Adjustable Office Task Chair (model OFC-MB-2TGR-670W) delivers a streamlined modern minimalist aesthetic defined by its coordinated light and dark grey upholstery, balanced proportions, and clean, uncluttered silhouette. Its contoured mid-back pairs with integrated wrap-around armrests for a cohesive visual profile, anchored by a polished five-star base that adds a refined, understated premium touch without excessive ornamentation. Overall dimensions measure 670 x 660 x 1070 mm, with a compact footprint that avoids overwhelming surrounding furniture arrangements, supported by a 700 mm five-star base span for stable visual balance. Built for consistent commercial and residential use, the chair features two-tone faux leather upholstery over a 12 mm thick bentwood plywood internal support frame. The seat uses 80 mm thick, 50 kg/m³ high-density molded polyurethane foam, while the backrest uses 50 mm thick, 35 kg/m³ medium-density polyurethane foam for targeted comfort. The base is polished chrome-plated aluminum, paired with a chrome-plated steel gas lift, 2.5 mm thick powder-coated steel tilt mechanism, and dual-wheel black nylon casters with PU tread. Integrated armrests include foam padding for soft, continuous forearm support, and the chair carries a net weight of 20 kg with a maximum recommended user weight of 150 kg. Core functional features support flexible, ergonomic task work: a 60 mm pneumatic height adjustment controlled by an under-seat lever locks at the user’s preferred setting, while 360-degree smooth swivel rotation enables easy access to surrounding work surfaces. The backrest offers 12 degrees of recline, with a knob-controlled tilt tension adjustment to match user preference, plus an upright lock that secures the backrest at a 90-degree vertical position for focused work. Dual-wheel casters enable smooth movement across both hard and soft floor surfaces, and the contoured mid-back shape aligns with the natural lower back curve to support 8 hours of daily task use. This chair is versatile across a range of settings, including private office workstations for managers or individual users, contemporary open plan office spaces, meeting and conference rooms for guest seating, compact home office areas, high-traffic hotel business centers, and executive meeting areas where its polished base conveys a premium appearance. For procurement planning, note that each unit ships across two cartons, with a packaged gross weight of 23 kg per set, total carton volume of 0.26 m³, and an assembly time of 40 minutes per set. A 20-foot container can accommodate 135 sets at 85% space utilization, making the model suitable for both small-scale fit-outs and larger bulk orders.
