Product Description

The Black High-Back Leather Executive Office Chair, model EXE-HB-BLK-01, presents a formal executive seating solution with a tall upholstered back, generous seat, fixed cantilever armrests, and a coordinated black five-star base. Its smooth black leather-look upholstery gives the chair a cohesive professional appearance, while the backrest uses a continuous upholstered surface with horizontal padded divisions. The padded arm tops and waterfall seat front soften the structured executive profile. Overall dimensions are 680 x 700 x 1230 mm, with 540 mm of clear width between the armrests. The chair is designed for a single occupant and supports a recommended user weight of 150 kg and user height up to 185 cm. Construction combines cushioning and metal support. The seat features an 110 mm thick polyurethane foam cushion with rounded waterfall front, a 90 mm finished cushion thickness, and 45 kg/m3 seat foam density. The backrest includes molded polyurethane padding over a formed back frame, 70 mm backrest padding thickness, a 240 mm lumbar support zone, and 35 kg/m3 back foam density. Foam resilience is listed at 40%. Inside, the seat uses a 2.0 mm steel plate or equivalent steel tube frame, while the back relies on a 1.5 mm steel tubular inner frame bonded to the back shell. The armrests are black powder-coated metal cantilever structures with padded top rails, providing fixed elbow support 230 mm above the seat. The 50 mm black steel telescopic gas lift includes a plastic shroud and connects to a black powder-coated die-cast aluminum or steel five-star base. Five independently pivoting twin-wheel nylon casters enable omnidirectional movement. Functionally, the chair offers 360-degree swivel, 100 mm of gas-lift height adjustment with side lever release, and a maximum seat height of 530 mm. The synchronized back tilt reclines 18 degrees from the upright working position, with a one-position upright lock and knob-adjustable tilt tension for users up to 150 kg. These features support posture changes between focused computer work, document review, and relaxed discussion. The chair is suited to director and manager offices, including use behind a 2000 mm executive desk, as well as private workstations for full-day computer and document tasks. It is also appropriate for senior meeting-room use around conference tables, dedicated home studies with a 750 mm wide circulation zone, and reception or administration areas with 760 mm work surfaces. For procurement, the unbranded chair ships as one set in two cartons, with packaged gross weight of 23 kg, 40-minute reference assembly time, and 135 sets indicated for a 20GP container at 85% space utilization. Buyers should specify hard-floor or soft-floor caster tread before bulk ordering and review the fixed-armrest design, black finish, and weight capacity against the intended workplace setting.
