The YUXIANG Mid-Back Padded Conference Swivel Office Chair, model OFC-MB-PU-001, is a purpose-built office conference chair designed for versatile professional and residential seating applications. Its streamlined silhouette pairs black smooth commercial-grade PU leather upholstery across the seat and back with light gray matte-finished molded plywood side support shells, anchored by a polished chrome-plated five-star base that lends a balanced, polished aesthetic suitable for refined work environments. The fixed integrated armrests are contoured directly into the side shell structure, offering 70mm wide support surfaces with a 540mm clear width between armrests to accommodate a broad range of user sizes. The overall form measures 610mm wide, 610mm deep, and 1000mm tall, with a 240mm tall dedicated lumbar support zone, a 90mm thick finished seat cushion, and 70mm thick backrest padding for consistent comfort. Construction centers on durable, commercial-grade components: internal seat and back frames use 14mm thick bent plywood or composite reinforced framing, supported by a 12mm molded plywood core structure. Seating surfaces are padded with 45 kg/m³ density foam that delivers 65% rebound, with 70mm thick seat foam and 50mm thick back foam wrapped in abrasion-resistant upholstery tested to 50000 cycles. The base is fabricated from 2mm thick polished chrome-plated steel, paired with 50mm diameter black polyurethane dual-wheel casters, a Class 3 chrome-plated steel gas lift for height adjustment, and a 3mm thick steel multi-lock synchro-tilt plate for reliable movement control. The chair weighs 18kg net, with a maximum weight capacity of 150kg for weight-activated tilt tension. Core functional features include 100mm of vertical seat height adjustment controlled via a side paddle lever, full 360-degree swivel rotation, 12-degree maximum back tilt with three lockable positions, weight-activated automatic tilt tension calibration, and smooth caster mobility suitable for hard floors and low-pile carpet. Upholstered padding supports 8 hours of recommended daily use. The chair is well suited for corporate conference rooms, where its contoured padding supports extended meeting sessions; private executive offices, where its mixed chrome and matte finish complements premium desk setups including 2.4m executive desks; open plan workstations, where its smooth casters enable easy repositioning between adjacent workspaces; home offices, where its height adjustment aligns with standard 760mm desk heights; and visitor reception areas, where its stable five-star base delivers safe temporary guest seating.
