Product Description

The Two-Tone Upholstered Mid-Back Swivel Executive Office Chair (model OFC-MB2T-725W, unbranded) features a polished, contemporary two-tone aesthetic defined by complementary light and dark grey faux leather upholstery. The seat and main backrest are finished in light grey stitched padded construction, while armrests and rigid wrapped side panels use dark grey faux leather for subtle visual contrast. The chair is supported by a polished chrome-plated five-star steel base fitted with black dual-wheel casters, delivering a streamlined, professional silhouette aligned with modern commercial and residential workspaces. Built for durable daily use, the chair integrates a 1.5mm welded steel internal frame under its upholstery, paired with a 2mm wall-thickness chrome-plated steel base, Class 3 safety-rated chrome-plated steel gas lift, and 3mm thick stamped steel tilt mechanism. The 90mm thick seat cushion uses 45 kg/m³ high-resilience polyurethane foam, while the backrest features molded polyurethane foam with a built-in contoured lumbar support zone. Fixed, wrapped armrests offer consistent forearm support at working height, with 540mm of clear width between armrests for comfortable seating access. Functional design supports varied work postures: pneumatic seat height adjustment delivers 60mm of travel via a side lever, 360-degree swivel enables multi-directional access to work surfaces, and the synchro-tilt mechanism allows 12 degrees of back recline with a lockable position to maintain upright working posture. Dual-wheel polyurethane casters roll smoothly across both hard and soft office floors, while the integrated lumbar support promotes lower back alignment during extended seating. The upholstery is rated for 50000 abrasion cycles, casters for 40000 rolling cycles, and the chair supports a maximum static load of 150 kg, with a recommended user weight of 120 kg. This chair is suited for private executive offices for management and senior staff using workstations for 8+ hours daily, open-plan office general staff workstations, conference rooms for extended collaborative sessions, modern home office remote work setups, and formal executive reception areas for visitor seating. It pairs optimally with 2.4m executive desks.
