The Yiankang Bentwood Upholstered Height-Adjustable Swivel Office Task Chair (model 1713C, part of the 1713C/1715C/1714C/1716C product line) features a streamlined armless profile defined by smooth, curved bentwood shell construction, with wrapped polished wood grain side trim that creates a refined, modern silhouette paired with neatly stitched PU faux leather upholstery. Its fixed 4-star polished die-cast aluminum base sits flush with anti-slip TPE rubber glide pads, with no protruding armrests to disrupt visual flow or block tucking under work surfaces. Four upholstery color combinations are offered, including camel brown paired with walnut, black with walnut, camel with white, and black with light blue, to align with varied interior palettes. The chair’s seat and back shell is formed from 8mm thick bent laminated plywood, mounted to the adjustment mechanism via 2.5mm thick powder-coated steel connection plates for stable structural support. Seat and back cushions are filled with high resilience cold-cured polyurethane foam, with a 60mm thick front edge on the seat and contoured waterfall edge design to reduce pressure on the back of the thighs during extended use. A chrome-plated steel class 3 gas lift connects the shell to the base, with a zinc-plated steel ball bearing swivel joint enabling smooth 360-degree rotation, controlled by a black reinforced nylon paddle lever positioned under the right side of the seat. The fixed, rigidly mounted backrest features curved rsed side edges to provide lateral torso support for upright working posture, with no recline or tilt function, and a defined lumbar support zone for consistent seated comfort. The upholstery is 1.2mm thick PU faux leather, rated to support 8 hours of dly use for light to medium duty applications. This chair is well suited for a range of commercial and residential spaces, including conference rooms where its tuckable armless design supports clean, uncluttered table layouts, reception and guest waiting areas where its polished bentwood and faux leather finish creates a welcoming professional appearance, compact home office workspaces, training rooms where stationary glides prevent unwanted rolling on hard flooring, executive office visitor seating that coordinates with wood veneer desk finishes, and high-traffic co-working spaces where its durable upholstery and commercial-grade construction hold up to frequent shared use. For procurement teams, key considerations include noting the chair’s knocked-down flat-pack design, which ships with all required hardware, with assembly completed by attaching the base to the gas lift and mounting the seat shell to the column. Product shipping is optimized for full contner loads, with clear volume and weight metrics available for freight planning. The product carries a 3-year standard commercial warranty covering the gas lift and core structural components, and supports a maximum static user weight of 120kg, with upholstery abrasion resistance aligned to regular commercial office use requirements.
