Product Description

The High-Back Black Leather Executive Swivel Office Chair presents a formal management seating profile through its tall upholstered back, black leather or leather-look facing, padded fixed armrests, and polished five-star base. A horizontal stitched division gives the continuous backrest a structured executive appearance, while curved polished aluminum or chrome-plated steel arm supports add a bright accent against the black upholstery. Its overall dimensions are 650 by 680 by 1220 millimeters, with 540 millimeters of clear width between the armrests, a 90 millimeter finished seat cushion, 70 millimeter backrest padding, and a 240 millimeter lumbar support zone. Construction combines comfort and durable support. The seat uses molded polyurethane foam at 45 kilograms per cubic meter, with a 100 millimeter front-edge cushion thickness over a 12 millimeter molded plywood or steel seat pan. The back uses layered polyurethane padding with 100 millimeters of visible side thickness around a 20 millimeter tubular steel or shaped plywood load frame. Arm pads are black padded components with molded polyurethane or a leather-like surface, and the central height system uses a 50 millimeter polished steel telescoping gas cylinder. The chair weighs 21 kilograms and is intended for users up to 150 kilograms. Design verification targets include a 500 kilogram static seat load, 120,000 backrest recline cycles, 100,000 gas-lift cycles, and 100,000 caster rolling cycles. Functional features support active office use. The seat rotates through a full 360 degrees and offers an 80 millimeter pneumatic height adjustment controlled by a side lever. The synchro-tilt mechanism provides 15 degrees of rear recline with proportional seat movement, multi-position locking at upright, intermediate, and reclined settings, and a five-turn knob for tilt tension. Fixed armrests provide support 230 millimeters above the seat. Five polyurethane twin-wheel casters allow omnidirectional movement on hard floors or low-pile carpet. This model is appropriate for executive offices, director and manager workstations, conference positions, reception areas, and management consultation spaces. For desk-based work, it is suited to a 760 millimeter high desk with adjustable monitor placement. It is recommended for commercial single-shift use of eight hours daily, including tile, wood, or laminate floors with the specified casters. Procurement planning should account for one unbranded set supplied in two cartons, model OCH-HB-LEA-5STAR-01, with a packaged gross weight of 23 kilograms, 0.26 cubic meter carton volume, and reference assembly time of 40 minutes.
