The Mid-Back Leather Swivel Executive Chair with Fixed Arms and Chrome Base is an unbranded office chair, model OFC-MB-LTH-ARM-CB01, designed for professional settings where a polished appearance and functional support are priorities. Its warm-gray, leather-look upholstery presents a refined executive style: the seat has a smooth surface with a stitched perimeter, while the padded back panel features vertical edge stitching. Fixed curved arms carry matching upholstered pads, supported by black molded polyurethane or polymer shells. The chair’s visual center is a polished aluminum alloy five-star base, paired with twin-wheel casters that give the seating profile a clean, commercial look. Comfort is built around layered padding and structured support. The seat uses a 90 mm molded polyurethane foam core at 45 kg/m3, and the back combines 70 mm polyurethane foam at 35 kg/m3 over a rigid board. A 240 mm lumbar support zone helps define the mid-back shape, while the 540 mm clear width between armrests provides room at the seat. Internally, the seat carrier targets a 15 mm plywood or steel-framed structure, and the back uses a rigid board or steel-reinforced carrier. The gas-lift and tilt mechanism are steel-based, with nylon dual casters fitted to the five-star base. Everyday operation is suited to desk-based work. A right-side lever controls the pneumatic seat-height adjustment, providing an 80 mm height change. The chair rotates 360 degrees around the central gas-lift axis, and the synchronized seat-and-back tilt offers a maximum rearward recline target of 12 degrees. Users can lock the recline at a selected working angle with the multi-position lever, while a rotary tension knob adjusts resistance according to user weight and preference. The fixed arms provide steady forearm support but do not adjust in height or width. The chair has a net weight of 17.5 kg and a recommended user weight capacity of 150 kg; specified durability targets include 100,000 seat-impact cycles and 100,000 caster-rolling cycles, with a 136 kg back static-load acceptance target. This model is appropriate behind a manager desk in a private executive office, at an open-plan workstation, and in meeting or consultation rooms for discussions at standard-height tables. It also fits hotel business centers, reception administrative areas, and home offices paired with a full-size desk using a work surface height of 760 mm maximum. For procurement planning, each set is supplied in two cartons, with packaged gross weight of 23 kg and carton volume of 0.26 m3. Reference assembly time is 40 minutes per set. A 20GP container can accommodate 135 sets at 85 percent space utilization, based on the supplied reference dimensions of 850 by 420 by 720 mm.
