Product Description

The High-Back Gray Upholstered Executive Swivel Chair presents a formal, management-oriented seating solution through its tall upholstered back, integrated head section, vertical seam lines, and continuous soft-faced gray seat surface. Polished chrome support loops connect the padded arm pads to the seat mechanism, while the chrome five-star base and black twin-wheel casters give the chair a structured mobile profile. Its overall dimensions are 680 by 700 by 1250 mm, with a 540 mm clear width between armrests. Fixed arm pads sit 230 mm above the seat, supporting forearms during keyboard and desk-side work. Construction combines a 100 mm molded foam seat cushion on a steel or plywood shell with a 70 mm contoured foam back pad over a rigid load-bearing back shell. The finished seat cushion thickness is 90 mm, the backrest padding thickness is 70 mm, and the fixed lumbar-contoured back includes a 240 mm lumbar support zone. Seat foam density is 45 kg/m3, back foam density is 35 kg/m3, and foam rebound rate is 45 percent. The gray smooth upholstery has a 60,000 Martindale abrasion rating, while its exact material type requires bill-of-materials confirmation. Chrome-plated welded steel forms the arm frame, a chrome telescopic gas lift uses a black lower shroud and 50 mm outer tube, and the multi-function metal seat mechanism provides the central control structure. Functionally, the chair rotates 360 degrees without a directional lock. A right-side paddle controls 100 mm of seat-height adjustment to a 530 mm seat height. The synchronous backrest recline offers an 18-degree maximum tilt from upright to relaxed posture, with a multi-position lock including upright and three intermediate positions. A rotating knob beneath the seat adjusts tilt tension to user body weight. The recommended weight capacity is 160 kg, and the recommended user stature endpoint is 190 cm. The chair has a net weight of 22 kg.
\nThis model suits private executive offices, director workstations, manager meeting rooms, formal conference or counseling rooms, and professional home-office studies. Its gray upholstery and chrome finish fit senior work environments, while the swivel base supports movement between discussion and computer tasks. For standardized commercial purchasing, the casters and gas lift are replaceable components. Buyers should plan for two cartons per set, a packaged gross weight of 23 kg per set, carton volume of 0.26 cubic meters per set, and an assembly time of 40 minutes per set. Material confirmation should be completed before final specification.
