Product Description

The High-Back Black Leather Executive Swivel Chair presents a formal executive profile with a tall structured back, integrated headrest zone, layered side bolsters, and vertical stitching channels. Its black leather-look upholstery is paired with dark mahogany-tone arm pads, polished metal supports, and a chrome-plated five-star steel base, producing a restrained appearance suited to traditional management interiors. The fixed arms provide rigid forearm support, while the five-star base and nylon casters create a clear mobile footprint beneath the seat. Overall dimensions are 660 by 720 by 1200 mm, with 540 mm of clear width between the armrests. Construction combines padded foam, a molded polyurethane seat cushion, layered polyurethane back padding, and a contoured raised lumbar zone. The finished seat cushion is 90 mm thick, backrest padding is 70 mm thick, and the lumbar support zone is 240 mm high. The seat uses a 12 mm molded plywood carrier bonded to foam and mounted to a steel mechanism; the back is supported by a 12 mm molded plywood or steel-reinforced composite panel with a welded tubular frame. Arm pads have a smooth dark wood-tone finish with black trim. Material composition and upholstery grade should be confirmed through the supplier bill of materials, because the supplied facts describe the surface as leather-look rather than confirming hide or polyurethane content. Procurement targets include 45 kg/m3 seat foam density, 35 kg/m3 back foam density, and a 50000-cycle Martindale abrasion target for the 1.2 mm leather-like facing. The chair supports daily desk use through a pneumatic height lift with a 100 mm stroke and right-side lever, complete 360-degree swivel, and synchronized or center-tilt action with an 18-degree maximum recline. A tension knob adjusts recline resistance, and a visible side lever provides a single-position upright lock for meeting use. The integrated high-back head zone supports the upper back and lower head without separate angle adjustment. Rated capacity is 159 kg for recommended user weight, with static load ratings of 200 kg for the tilt mechanism and 1134 kg for the base; caster rolling durability is rated at 100000 cycles. It is appropriate for director offices, senior manager workstations, boardrooms, private management spaces, and premium reception or consultation rooms. Pair it with a desk surface up to 760 mm high, and use it on hardwood, tile, commercial vinyl, or low-pile carpet protected by a chair mat. Purchasers should plan for two cartons per set, 0.26 m3 of package volume, 23 kg packaged gross weight, and 40 minutes of assembly time. A 20GP container can accommodate 135 sets at 85 percent space utilization.
