Product Description

The Black Padded Mid-Back Executive Office Chair with Chrome Frame presents a polished, professional seating solution defined by its black upholstered body and bright chrome structure. Its segmented backrest uses horizontal separation and tailored edge seams, while the smooth black seat sits between fixed wraparound chrome armrests. The one-piece bent-steel arms rise 230 mm above the seat, and the 540 mm clear width between them gives open seating space without losing the supportive, enclosed executive profile. The polished chrome-plated steel frame flows into a five-star base, creating a formal contrast suited to offices that want a traditional managerial look. Comfort is built around layered padding. The finished seat cushion is 90 mm thick, using an 80 mm polyurethane foam core with a 45 kg/m3 density target over a rigid seat deck. The backrest has 70 mm of finished padding, with a 60 mm polyurethane foam core at a 35 kg/m3 density target attached to a supportive shell, and includes a 240 mm high lumbar support zone. Internal support is provided by a steel plate or reinforced bent-wood composite seat structure, paired with a steel or molded back support panel. The 50 mm class-4 chrome-plated gas lift, 2.5 mm powder-coated steel synchro-tilt mechanism, and chrome five-star base form the chair’s robust central structure. Black nylon twin-wheel casters complete the mobile base. The chair supports 360-degree swivel movement and offers a 100 mm seat-height adjustment through an underside lever, producing a 530 mm seat-height range. Users can recline through a 15-degree synchro-tilt motion, lock the chair in the upright position or select free-tilt movement, and adjust spring tension with a control knob calibrated for users up to 150 kg. The five dual-wheel casters allow omnidirectional movement on hard floors and low-pile carpet, making the chair practical for daily desk work and room repositioning. This model is well suited to manager and executive desks, open-plan workstations, conference settings, reception or consultation areas, and dedicated home offices. It pairs naturally with a standard 760 mm desk height and offers a compact professional presence in spaces where a larger high-back chair would be visually dominant. Procurement teams should note that the visible upholstery material requires bill-of-materials confirmation, so finish selection and surface expectations should be clarified before ordering. The chair is supplied as one set in two cartons, with packaged weight of 23 kg and a reference assembly time of 40 minutes per set. Replacement planning should account for the specified caster, gas-lift, mechanism, and foam specifications, while buyers evaluating heavy shared use should consider the stated 150 kg user capacity, 50,000 double-rub fabric abrasion rating, and 100,000-cycle caster rolling durability.
