Product Description

This unbranded High-Back Black Leather Executive Office Chair (model EXE-WD-001-BLK) balances polished professional aesthetics with structured ergonomic support, designed for premium seating across formal work environments. Visually, the chair presents a sleek, cohesive silhouette defined by its tall contoured high back, smooth black leather upholstery, and warm solid wood structural accents on armrests and the five-star base, creating a refined, authoritative look that complements traditional and contemporary upscale office design schemes. The 730 x 720 x 1280 mm frame offers 540 mm of clear width between armrests, with generously padded contact surfaces: the 90 mm thick seat cushion and 70 mm thick backrest wrap around a 240 mm tall built-in contoured lumbar support zone to cradle the torso during extended work sessions. Construction prioritizes durable, premium materials throughout. Seat and back surfaces are upholstered in 1.2 mm thick black top-grain leather, stitched with high-tensile bonded polyester thread at a 3 mm seam pitch to deliver 50,000 cycles of abrasion resistance. Padding is formed from 45 kg/m³ high-density molded polyurethane foam with a 60% rebound rate, supported by an 18 mm thick plywood inner seat frame. Armrests feature solid polished wood frames topped with leather padding at contact points, while the five-star base uses solid finished wood paired with a chrome-plated metal center hub. Functional hardware includes chromed metal fasteners, a Class 3 chromed steel pneumatic gas lift rated for 100,000 durability cycles, a 3 mm thick stamped steel synchro tilt chassis, and dual-wheel nylon casters with chrome accents. The chair weighs 35 kg and supports a maximum static load of 159 kg for adult users. Core functional features support flexible, comfortable use: the chair enables 360-degree full swivel, 100 mm of pneumatic seat height adjustment via a side lever, and synchro tilt with a 15-degree maximum recline angle, paired with infinite position tilt lock to secure upright or reclined postures and a tension knob to adjust recline resistance to match user weight. Dual-wheel casters glide smoothly across hard floors and low-pile carpet for easy repositioning. This chair is suited for manager and executive private offices, formal boardrooms and conference spaces, high-end reception and visitor meeting areas, and dedicated home executive workspaces, pairing optimally with 2.4 m executive desks. For procurement, note that each unit ships across 2 cartons with a total packaged gross weight of 23 kg and total carton volume of 0.26 m³, requires 40 minutes of assembly per set, and fits 135 units in a 20GP container at 85% space utilization. No specialized tools or additional accessories are included with standard orders.
