Product Description

The High-Back Black Upholstered Swivel Executive Office Chair with Wood Trim, model EXE-WD-74083117, is an unbranded traditional executive seating solution defined by polished, formal visual design. It features a tall 630 mm high back upholstered in smooth black polyurethane faux leather, paired with stained solid mahogany-tone hardwood accents on fixed armrest frames and a wide five-star base finished to a polished sheen. The design balances structured, professional lines with soft padded surfaces, creating a stately, refined silhouette that reads as deliberate and upscale rather than overly casual. With a fully assembled footprint of 740 x 830 x 1170 mm, the chair’s proportions feel substantial without overwhelming surrounding workspace furniture, and the matching black padded armrest tops align seamlessly with the seat and back upholstery for a cohesive look. Built for long-term daily use, the chair’s construction prioritizes durability and consistent support. Seat and back cushions are formed from high-density polyurethane foam, with 100 mm thick 40 kg/m³ foam at the seat and 80 mm thick 30 kg/m³ foam at the back, upholstered in faux leather rated for 50000 Martindale abrasion cycles to resist wear from regular use. Internal support panels use 15 mm thick plywood, while the tilt chassis is fabricated from 3 mm thick cold-rolled steel, paired with a Class 4 steel pneumatic gas lift and 50 mm diameter black nylon hooded casters. The solid wood five-star base and fixed armrest frames add structural rigidity, and the assembled chair has a net weight of 24 kg with a recommended static user weight capacity of 150 kg. Core functional features support both comfort and flexible work patterns. The lever-operated pneumatic height adjustment offers 100 mm of travel, reaching a maximum seat height of 520 mm to align with standard 760 mm tall office desks. Users benefit from full 360-degree swivel rotation for easy access to all areas of a desk, a synchronized seat and back tilt rocking function with an adjustable tension knob, and an upright tilt lock to secure the chair in place for focused work. Built-in contoured lumbar padding reduces lower back strain during extended work sessions, the fixed padded armrests deliver stable forearm support, and the five casters roll smoothly across both hard flooring and carpeted office surfaces. This chair is suited to a range of professional and dedicated private work settings. Its formal traditional styling complements private C-suite and management executive offices, while its conservative polished appearance is an ideal match for client-facing spaces in law and financial firms. It works equally well as boardroom and executive conference room seating, creates a polished first impression in reception and management waiting areas, and offers long-sitting comfort for dedicated home office studies. Procurement teams should note that each unit ships across two cartons, with a total packaged gross weight of 23 kg and total carton volume of 0.26 m³, requiring 40 minutes of assembly time per set.
