The High-Back Orange Leatherette Executive Swivel Office Chair, model EO-HB-OR-01, is an unbranded executive seating solution with a distinctive visual character. Its tall, curved back is upholstered in smooth orange leatherette with visible perimeter stitching and seam lines, set against a gray molded polymer structural shell with a curved side spine. Light-gray molded polymer arm posts carry dark-gray padded or hard polymer caps, while a chrome gas lift and polymer five-star base with twin-wheel casters complete the polished commercial appearance. Construction layers visual style with structured support. The seat uses a molded polyurethane foam core 80 mm thick, with a finished cushion thickness of 90 mm and density target of 45 kg/m3. The shaped back cushion is 60 mm thick at the lumbar center, with a finished backrest padding thickness of 70 mm and foam density target of 35 kg/m3. An integral raised cushion forms the lumbar support zone, upholstered in matching orange leatherette. Beneath the seat is a black steel-and-polymer synchronized tilt mechanism with lever and tension knob, paired with a chrome-plated telescoping gas lift. The upholstery carries a 50,000 Martindale abrasion target. Functionally, the chair supports a full range of executive desk movements. A right-side pneumatic lever gives 100 mm of seat-height travel from 450 to 530 mm, and the central bearing allows continuous 360-degree swivel. The synchronized tilt mechanism moves the back through 23 degrees to a 118-degree recline, with a locking lever for upright or selected recline positions and a rear rotary knob to adjust resistance to body weight. Fixed-height armrests place 250 mm pads 230 mm above the seat, leaving 540 mm of clear width between them, while the raised curved lumbar section provides passive lower-back contact at 230 mm height. The high-back form suits managers’ offices and reception or consultation settings, where the orange leatherette creates a formal yet design-forward impression. It also fits meeting rooms, open-plan workstations, project areas, and home offices. The 670 mm footprint works with standard desk bays and 760 mm desks, and twin-wheel casters allow easy repositioning. With a recommended user weight of 135 kg and durable upholstery target, it is suited to daily multi-user rotation as well as individual use. Procurement teams should note the chair ships as one set in two cartons, with packaged gross weight of 23 kg and a reference assembly time of 40 minutes. The listed carton dimensions are 850 by 420 by 720 mm, with carton volume of 0.26 m³ per set and indicative 20GP loading of 135 sets at 85 percent space utilization. Buyers should plan for assembly, confirm floor-caster suitability, and evaluate the orange finish against interior schemes and shared-space branding.
