The OC-MID-1024 is an unbranded white upholstered mid-back office task chair with fixed arms and a chrome base, designed for versatile use across professional and residential work settings. Its visual profile features a smooth light off-white upholstered seat and backrest, accented by a single horizontal stitched seam at the lower lumbar panel, paired with white rigid plastic T-shaped armrests that connect to the seat and back frame. The polished chrome five-star base, with a ribbed upper surface, supports black nylon twin-wheel swivel casters with chrome housing rings, creating a balanced, minimalist aesthetic that fits both modern and neutral interior schemes. Constructed with molded contoured polyurethane foam padding for the seat and backrest, the chair includes an integrated recessed lumbar pad for targeted lower-back support. The seat rests on a load-bearing base panel, while the backrest encloses a bent plywood inner support frame. A chrome-plated steel gas lift with a black plastic adjustment collar connects the seat assembly to the chrome-plated steel five-leg base, and a black steel recline mechanism with a side-mounted plastic height-adjustment lever sits beneath the seat. Fixed armrests are mounted rigidly to the side frame, and all casters clip into the base sockets. Functionally, the chair offers pneumatic seat height adjustment via the side lever, full 360-degree swivel rotation, and a recline mechanism with backward seat and back rotation controlled by an under-seat lever, plus a rotary tension knob to adjust recline resistance. The fixed T-shaped armrests provide stable forearm support, while the five swivel dual-wheel casters enable smooth mobility across hard or carpeted surfaces. Its five-leg base distributes user weight evenly for consistent static and dynamic balance. The chair ships in knockdown flat-pack form and is user-assembled by attaching the gas lift to the base, inserting the mechanism into the gas lift, and clicking casters into the base sockets. This task chair is suited for a wide range of spaces. It works well in general office workstations, including open-plan offices and individual desks, for daily computer-based tasks. Its uniform aesthetic and swivel mobility make it a practical choice for meeting and conference rooms, while its moderate footprint and clean design fit home offices and residential study rooms. It also serves administrative and reception areas, where ergonomic adjustment and a professional appearance are priorities, as well as co-working and shared desk environments, where quick height adjustment and easy mobility support frequent repositioning. For training and seminar rooms, its lightweight build and rolling casters allow for flexible rearrangement of room layouts. For procurement planning, each unit is packed in a single flat-pack carton, with the seat-back sub-assembly shipped separately from the base, gas lift, and casters. Single-person assembly using basic tools is expected to take 30 minutes per unit. The chair supports a recommended maximum user weight of 120 kg, with a five-star base static load rating of 1000 kg. Seat foam has a density of 45 kg/m³, while back foam has a density of 35 kg/m³, and the upholstery offers abrasion resistance of 50,000 Martindale cycles. Nylon casters have a rolling durability of 100,000 cycles on hard surfaces.
