Product Overview & Construction Details

The Yiankang Model 1355-X08 armless bentwood padded adjustable office task chair features a streamlined, space-efficient silhouette defined by smooth bentwood construction and neutral matte black upholstery, paired with a polished chrome five-star base for a cohesive modern aesthetic. Its armless, mid-back form creates a slim, unobtrusive profile that tucks fully under standard desk depths to minimize visual clutter in tight layouts. Built around a bent laminated plywood shell with a natural light oak finished edge, the chair uses thick high-resilience polyurethane foam for both seat and back padding, upholstered in smooth black matte faux leather with consistent commercial-grade stitching. The polished chrome-plated steel five-star base supports a commercial-grade Class 3 chrome gas lift, fitted with black nylon twin-wheel casters and connected via a steel tilt-locking chassis. A reinforced nylon paddle lever positioned under the left seat operates height adjustment controls. Core functional features include full 360-degree swivel rotation, smooth omnidirectional rolling suitable for hard flooring and low-pile carpet, and pneumatic seat height adjustment to align with standard worksurface heights. The backrest is set in a fixed ergonomic upright position, with the seat locked in a flat horizontal orientation for stable task performance, and a contoured lumbar support zone for comfortable seated posture over regular dly use. The armless design eliminates protruding obstructions to allow flexible movement and close positioning to work surfaces. This chair is well suited for high-density open plan office workstations, compact home offices and study spaces, flexible meeting and conference room layouts, light-traffic reception and guest waiting areas, and pring with height-adjustable standing desk setups. Its understated finish blends seamlessly with both contemporary commercial interiors and Scandinavian or modern residential decor. For procurement planning, note that units ship in compact knockdown packaging, with straightforward assembly required on site, and predictable contner loading quantities for bulk orders. The chair is rated for a maximum recommended user weight aligned with commercial office seating standards, with durable component performance suited to regular dly use. For installations on high-pile carpet, soft floor casters are recommended to mntn smooth rolling function; material and specification confirmation is recommended prior to final bulk order placement to align with project-specific requirements.
