The Black Leather-Look High-Back Executive Office Chair presents a formal, high-back profile in black, with a broad padded seat and tall backrest joined by fixed T-shaped armrests. Stitched side borders define the smooth back upholstery, while a polished aluminum five-star base gives the chair a structured executive appearance suited to wood, laminate, and professional desk settings. Its overall footprint is 720 x 680 x 1230 mm, with a 530 mm-wide seat, 520 mm seat depth, 580 mm highest seat position, 520 mm-wide backrest, and 700 mm backrest height. The seat and back each use 102 mm of padded cushioning, creating a substantial visual and physical seating form. Construction combines a black leather-look surface, molded foam cushions, fixed polymer armrests, and a polished radial aluminum base. Procurement targets include 60 kg/m3 foam density for the seat and 35 kg/m3 for the back, with a 12 mm plywood seat shell and matching targeted 12 mm plywood or framed back support. The arm supports are matte black fixed polymer or painted metal, fitted with flat black polymer or upholstered pads. A chrome-plated steel telescopic pneumatic cylinder provides central support through a swivel load path connected to the five-star base. The chair is built for everyday office movement and posture control. A lever operates the gas lift over its 100 mm stroke, while the central bearing column allows 360-degree rotation without turning the base. The tilt mechanism offers a 16-degree back recline, five selectable lock positions, and an under-seat tension knob calibrated for users up to 125 kg. Five twin-wheel casters provide ten floor-contact wheels for rolling and directional tracking. Fixed armrests deliver stable forearm support but do not adjust in height or width. The recommended daily seating duration is 8 hours. This model is appropriate for director and manager offices, open-plan workstations, conference rooms, reception or administrative areas, and private studies or home offices. Its restrained black finish works where a traditional executive look is preferred over mesh or gaming-style seating. Procurement teams should select hard-floor or carpet-rated 65 mm twin casters according to the installation surface. The unbranded chair is supplied as one set in two cartons, with a reference assembly time of 40 minutes per set, packaged gross weight of 23 kg, and carton volume of 0.26 cubic meters per set.
