The Executive Swivel Chair with Brown Upholstery and Polished Aluminum Base presents a formal high-back silhouette suited to professional settings. Brown full-grain-look leather or coated leather fabric covers the contoured back, seat, and continuous arm pads, with matching edge stitching reinforcing the tailored appearance. Integrated upholstered armrests flow into the side shell, while a black textured resin or carbon-fiber-pattern protective insert adds contrast at the lower side. The chair sits on a polished aluminum five-star base with nylon twin casters, creating a refined executive profile from the desk-facing front to the visible base. Comfort is built around differentiated padding. The seat uses high-resilience polyurethane foam at 45 kg/m3 and is 90 mm thick, while the molded back foam is 35 kg/m3 and provides 70 mm of padding in the lumbar region. The 240 mm lumbar support zone and 540 mm clear width between armrests support a structured, formal sitting position. Internally, the load-bearing structure uses a 12 mm molded plywood or 4 mm reinforced polymer back shell, with a 12 mm molded plywood seat plate bonded to both cushion and mechanism. The black powder-coated steel multi-position synchro-tilt mechanism, chrome-plated steel gas lift, and polished base complete the primary construction. Functional controls are designed for daily office use. A right-side lever operates the pneumatic lift through its 80 mm stroke, accommodating users requiring seat heights from 450 to 530 mm. The chair swivels 360 degrees around the central gas-lift axis, and the synchro mechanism permits a 15-degree recline with coordinated seat movement. A locking lever secures the back at four selected incline positions, while the rear rotary knob adjusts tilt resistance for users up to 150 kg. Fixed arm pads sit 210 mm above the seat and are 90 mm wide. Five twin-wheel casters enable omnidirectional movement on hard floors and low-pile carpet. This model is appropriate behind a manager desk, at a private workstation, and in senior conference or meeting positions. Its polished appearance and wipe-clean upholstery also suit hotel business centers, consultation rooms, and reception management offices where computer work alternates with face-to-face discussion.
