The YUXIANG Mid-Back Two-Tone Swivel Executive Office Chair (model OFM-MB-TT-780) delivers a polished, professional seating solution anchored by a deliberate two-tone visual design. Its seat and inner back are finished in commercial-grade tan PU leather, paired with a dark gray rigid polymer composite outer back and arm shell, creating a sleek, balanced silhouette suited to formal and semi-formal work environments. Fixed integrated armrests curve continuously from the frame, positioned 200mm above the seat surface to align with natural arm positioning, while the curved mid-back structure rises 670mm above the seat to offer targeted lumbar support. The chair mounts to a polished chrome-plated steel five-star base, presenting a cohesive, refined profile that avoids overly bulky visual weight. Construction prioritizes long-term commercial durability across all core components. The seat and back are padded with high-density molded polyurethane foam, with integral molded foam matching the seat upholstery covering the armrests for consistent comfort. Internal support comes from a 1.5mm thick welded steel tube frame, with a 3mm thick powder-coated steel tilt mechanism chassis, Class 4 rated chrome-plated steel gas lift column, and dual-wheel casters with polyurethane tread on nylon hubs. The chair supports a maximum user weight of 181 kg, with performance ratings validating extended regular use across repeated adjustment and movement cycles. Core practical functions support flexible, comfortable use throughout extended work sessions. A pneumatic gas lift enables 60mm of vertical seat height adjustment, with a maximum seat height of 520mm and maximum total chair height of 1150mm to accommodate a range of desk setups. The central swivel joint allows full 360-degree rotation, while the swivel tilt mechanism offers 15 degrees of maximum recline that locks securely in the upright position; an under-seat knob lets users adjust tilt tension to match their personal preference. The five dual-wheel casters roll smoothly across both hard and soft floor surfaces without causing damage. This chair is well suited for a wide range of professional and personal work spaces, including private executive offices, conference meeting rooms, home office workspaces, executive reception areas, open-plan corporate workstations, and client consultation rooms. Its commercial-grade construction stands up to daily high-frequency use in shared settings, while its refined finish maintains a professional impression for visiting clients and colleagues. For procurement planning, note that each unit ships as one set across two cartons, with a reference assembly time of 40 minutes per set. The packaged configuration supports efficient bulk shipping, with 135 sets fitting in a 20GP container at 85% space utilization, making the model a practical choice for both small-scale office updates and large-scale workspace fit-outs.
