Product Overview & Construction Details

The Bentwood Upholstered Swivel Armless Office Task Chair, model TASK-BW-001, is an unbranded light-task seating solution defined by a streamlined, mid-back silhouette that presents a smoothly curved bent plywood form with tailored black upholstery. The design features a contoured seat and integrated backrest set atop a polished five-star base, with no protruding armrests to create a compact, uncluttered profile that tucks fully under standard desk surfaces to reduce unused floor space when not in use. Construction centers on a bent laminated plywood shell finished with natural oak veneer on the rear back face, coated in a clear matte lacquer to highlight visible wood grain. The seat and front contact surface of the backrest are upholstered in smooth black PU leather with even, consistent edge stitching, padded with high-resilience polyurethane foam for seated support. The base is formed from polished chrome-plated steel, fitted with black nylon twin-wheel casters and a chrome-plated steel Class 2 gas lift, with a glass-filled nylon paddle lever and steel plate tilt mechanism housed discreetly under the seat. Core functional features include tool-free pneumatic seat height adjustment that locks at any position within its full range, a backward tilt function with adjustable tension and an upright lock position, and 360-degree swivel paired with casters that roll smoothly across hard flooring and low-pile carpet without scratching surfaces. The armless, compact footprint supports flexible positioning across a wide range of spaces, including residential home offices and student study areas, open-plan hot-desking zones and collaborative workstations, minimalist or Scandinavian-styled conference rooms, reception and retail service counters, and creative studios with flexible layout needs. Its neutral oak and black finish coordinates easily with both warm wood and industrial interior palettes. For procurement teams, key considerations include confirming final material specifications such as veneer species, PU grade, foam density and caster stem details directly with suppliers prior to bulk order, as these details are subject to production variation. The chair ships in a single flat-packed carton with standard protective packaging for upholstered and wood components, with an assembly time suitable for quick on-site setup, and packaging dimensions optimized for high-volume container loading for commercial projects. The product is rated for light task use, with weight and durability benchmarks aligned to regular daily use in low to medium-traffic work settings.
