产品描述

The Yiankang mid-century armless swivel office chair, model OC-BW4S-TAN-001, pairs warm retro styling with functional task seating for residential and light commercial settings. Its visual profile is defined by a gracefully curved walnut-veneered bentwood back, smooth matte tan faux leather upholstery, and a polished 4-star die-cast aluminum base fitted with non-marking black polymer glides. The armless form creates a clean, streamlined silhouette that sits low against desk surfaces, with the reflective polished metal base adding a subtle refined contrast to the warm wood and tan upholstery tones. Construction centers on durable, everyday-use materials: the bentwood back structure supports a thin layer of polyurethane foam under the tan upholstered front panel, while the contoured seat uses high-density molded polyurethane foam wrapped in thin polyester batting for soft, rounded edge feel, with a thick padded cushion for seated comfort. The one-piece polished aluminum base connects to the seat via a chrome-plated steel gas lift and steel ball bearing swivel mechanism, with an internal powder-coated steel support plate reinforcing the seat pan. Stitched upholstery follows standard durable seam spacing, and the faux leather surface is formulated to hold up to regular daily contact. Core functional features support flexible desk use: the chair delivers full 360-degree unobstructed swivel rotation, plus pneumatic seat height adjustment controlled by a side lever under the right seat edge, with infinite lock positions between the lowest and highest height settings to align with varying desk heights. The fixed 105-degree back angle offers consistent upright support, while the armless design allows the chair to tuck fully under desk surfaces to save unused floor space. The non-marking glides are engineered for hard flooring surfaces including wood, tile, and vinyl, preventing scuffs without the unwanted movement of casters, and the wide 4-point base delivers stable stationary support during daily use. This chair fits a wide range of spaces: it works seamlessly in compact home office workstations, where its mid-century aesthetic aligns with residential interior design, as well as small meeting rooms where stable seating and swivel access support easy conversation. It also serves well as a bedroom vanity or study desk chair, fits open-plan co-working hot-desking stations thanks to its easy-clean, stain-resistant upholstery and compact footprint, and complements design studio creative workspaces where its modern retro styling pairs with upright support for drafting or project work. For procurement teams, key considerations include confirming final bill of materials details for upholstery type, gas lift rating, and internal component specifications with suppliers prior to bulk order, as final production configurations may align with alternate engineering reference values. The chair ships in knock-down flat packaging for efficient freight loading, with straightforward assembly requiring only basic hand tools. It is rated for up to 8 hours of daily use for regular light commercial or residential applications, supporting a static weight capacity aligned with standard armless task seating for general user needs. The smooth faux leather surface supports quick wipe-down cleaning between users, making it practical for shared seating environments, while its timeless finish reduces the need for frequent style updates in evolving interior schemes.
