产品描述

The Mid-Back Brown Leather Executive Swivel Chair, model EC-MID-BR-AL5, presents a professional executive seating form with a brown leather-look seat and upholstered padded back. Its visual character is defined by a horizontal back seam that separates the upper shoulder area from the lower lumbar zone, stitched side borders, and polished aluminum curved-loop arms that continue visually from the seat toward the back. The arm structure sits above a polished five-star base, producing a refined contrast between warm brown upholstery and bright metallic detailing. Overall dimensions are 640 by 660 by 1020 millimeters, with 540 millimeters of clear width between the fixed armrests. Construction combines upholstery, foam, metal, and mobility components. The seat uses a shaped polyurethane molded cushion with a 90-millimeter finished cushion thickness and a 45 kilograms per cubic meter density target. The back provides 70 millimeters of polyurethane padding over a steel reinforcing frame, with a 240-millimeter lumbar support zone. The brown wear layer has a 1.2-millimeter surface thickness and a 50,000-cycle abrasion acceptance target, while the inner seat carrier is specified as molded plywood or engineered composite. Material grade for the leather-look upholstery should be confirmed through the supplier bill of materials before final specification. The chair is built around a chrome-plated steel Class 3 telescopic gas lift, a black steel mechanism, polished aluminum arms and base, and nylon twin casters. It supports full 360-degree swivel movement, pneumatic seat-height adjustment, and synchronized seat-and-back tilt through 15 degrees with an upright lock position. An under-seat knob regulates tilt resistance, and the fixed polished arms offer 230 millimeters of forearm support. The five twin-wheel casters are intended for hard floors and low-pile carpet, supporting movement around a standard desk or meeting table. Performance references include a 135-kilogram recommended user weight capacity, 8-hour recommended daily use, 100,000-cycle seat impact durability, 100,000-cycle caster rolling durability, and a 200-kilogram tilt mechanism static load rating. These features suit manager offices, executive workstations, conference rooms, reception meeting areas, and private home offices with wood, leather, or modern metal finishes. For coordinated projects, the chair can be ordered with matching brown visitor chairs to maintain boardroom consistency. Procurement teams should plan for two cartons per set, a packaged gross weight of 23 kilograms, and a reference assembly time of 40 minutes per chair. The reference carton dimensions are 850 by 420 by 720 millimeters, with a total reference carton volume of 0.26 cubic meters per set. Buyers should verify upholstery grade, component finishes, and final assembly hardware with the supplier, especially when the chairs are intended for premium client-facing spaces or standardized multi-room installations.
