Product Description

The High-Back Black Leather Executive Swivel Chair, model EXEC-HB-PU-ALU5presents a formal executive silhouette with a tall upholstered back, generously padded seat, and polished continuous-loop arm structure. Its black smooth leather-look upholstery is paired with a polished aluminum alloy frame and five-star base, creating a restrained commercial appearance suited to premium office interiors. The two-zone back panel rises into a high-back form, while the cantilever arms provide a continuous visual line from armrest to base. The layout centers on a chrome-plated steel gas cylinder, five caster points, and a side-operated mechanism, giving the chair a balanced, conventional executive layout. Construction combines padded upholstery with metal and steel support. The seat uses a 90 mm molded polyurethane foam cushion over a molded plywood or reinforced polymer internal carrier, while the back uses polyurethane foam padding over a 20 x 2.0 mm steel tubular inner frame. Seat foam density is 45 kg/m3 and back foam density is 35 kg/m3, with foam resilience specified at 40 percent. The arm top rail is an integrated padded or leather-wrapped surface, 45 mm wide, and the chair moves on black nylon twin casters. The black upholstery is rated for 50,000 Martindale abrasion cycles, and the polished base has a static load rating of 500 kg. Recommended user weight capacity is 150 kg. Functionality is designed for daily desk work and meeting use. The chair swivels 360 degrees, and the right-side lever controls pneumatic seat-height adjustment through a 90 mm stroke. A synchro-tilt mechanism allows the back to recline 15 degrees rearward with coordinated seat and back movement. Users can adjust tilt resistance with an under-seat knob across five effective turns, select an upright lock, or use free-float mode through the seat-side lever. Fixed arm support sits 240 mm above the seat, while five twin-wheel casters support movement on hard floors and low-pile carpet. This unbranded executive chair is suitable behind executive desks, including a recommended 2.4 m executive desk, as well as manager workstations at standard desk height. It also fits boardrooms, meeting spaces, private consultation rooms, and home offices where a commercial appearance is desired. Procurement teams should note the chair is supplied as one set in two cartons, with packaged gross weight of 23 kg and reference assembly time of 40 minutes. The clear armrest width, black finish, polished metal frame, and high-back profile should be checked against desk clearance, room styling, and user requirements before ordering.
