产品描述

The mid-back black faux leather swivel office task chair (model OTB-MB56-PU-CRM, unbranded) presents a streamlined, professional silhouette tailored to modern work environments, with a coordinated black and polished chrome finish that balances understated formality and functional appeal. Its five-star chrome base sits below a contoured seat and mid-rise backrest, flanked by fixed cantilever armrests that align neatly with standard desk surfaces without protruding excessively into surrounding space. The chair’s overall dimensions are structured to deliver comfortable support without unnecessary bulk, creating a compact footprint that adapts well to varied layout configurations. Constructed for regular daily use, the chair features 1.5 mm thick black PU faux leather upholstery over high-density cold-cured polyurethane foam padding, supported internally by an 18 mm curved plywood seat panel. Its frame, cantilever armrest structure, and five-star swivel base are finished in polished chrome-plated steel, paired with a Class 3 chrome-finished steel pneumatic gas lift and 2.5 mm thick steel locking tilt chassis. Armrests are topped with firm black polyurethane pads, while 60 mm black nylon dual-wheel casters mount to each base leg for stable movement. The upholstery is rated to withstand 50000 double rubs, casters deliver reliable performance through 40000 rolling cycles, seat foam carries a 45 kg/m³ density with 40% rebound rate, and the chair supports a maximum user weight of 136 kg, with a net product weight of 15.4 kg. Core functional features support comfortable, flexible work: a right-side lever operates the pneumatic lift to adjust seat height across a 100 mm range, locking automatically at the selected position when released, with a maximum seat height of 510 mm and minimum of 410 mm from floor to seat top. A central swivel joint enables full 360-degree horizontal rotation, while the synchronized tilt mechanism allows seat and back to recline up to 12 degrees, with an upright lock position and under-seat rotary knob to adjust tilt resistance to match user weight. Fixed armrests sit 210 mm above the seat surface for stable upper body support, and dual-wheel casters roll smoothly across both carpet and hard floor surfaces. This chair is suited for a wide range of professional and hybrid work settings. It works well for long-duration desk work at open office workstations paired with standard 760 mm height desks, fits compact home office spaces with 1.4 m wide desks without creating visual or physical clutter, complements formal conference and meeting room interiors, delivers a polished appearance for reception and front desk guest and staff seating, suits entry-level private manager offices, and supports easy reconfiguration for training room layouts thanks to its mobile design. For procurement planning, note that each unit ships across two cartons, with a packaged gross weight of 23 kg per set and total carton volume of 0.26 m³ per set. Assembly takes 40 minutes per unit, and a 20GP container can hold 135 sets at 85% space utilization to support bulk order logistics calculations.
