The Yiankang 1708B-X08 is a two-tone faux leather upholstered mid-back swivel office chair designed for versatile commercial and residential seating applications. It features a polished chrome-plated five-star base paired with black nylon twin-wheel casters, presenting a sleek contemporary profile defined by deliberate color blocking: dark charcoal PU faux leather covers the seat surface and inner backrest, while soft light blue PU faux leather panels the outer backrest and armrest sides for subtle visual contrast. Fixed integrated wrap-around armrests extend seamlessly from the seat shell to deliver consistent forearm support, and the contoured mid-height backrest is shaped to deliver built-in lumbar support without separate adjustable pads. Its overall proportions align with standard mid-back task chair dimensions, with a compact footprint that adapts well to constrained floor spaces. Constructed with a hidden 15mm thick molded plywood inner frame for structural stability, the chair uses differentiated high-resilience polyurethane foam for targeted comfort: 45kg/m³ density foam forms the 90mm thick seat cushion, while 35kg/m³ density foam creates the 70mm thick backrest padding, with a 45% foam rebound rate to resist permanent indentation over long-term use. The 1.2mm thick PU upholstery offers stain-resistant, wipe-clean maintenance with standard mild cleaning products, suited for high-traffic use. Mechanical components include a Class 3 chrome-plated steel gas lift, 2.5mm thick steel tilt mechanism chassis, and powder-coated steel adjustment lever positioned under the right seat edge. Functional features include 100mm of vertical seat height travel, full 360-degree swivel rotation, 12-degree backward synchro-tilt with adjustable tension and upright position lock, and smooth omnidirectional rolling suitable for both hard floors and low-pile carpet, with no caster lock mechanism. The chair supports a maximum recommended static user weight of 150kg, and comes with a 3-year warranty covering frame and mechanical components, with casters rated for extended rolling durability over hard flooring. This model fits a broad range of spaces: it supports multi-hour seated work at private office workstations and open plan task positions, where its quiet casters and polished chrome base minimize disruption in shared environments. It works equally well in conference and meeting rooms, as its fixed armrest height aligns with standard conference table dimensions to support collaborative discussion, and its modern two-tone aesthetic suits guest-facing reception areas and temporary visitor seating. For residential use, it is an ideal fit for home office workspaces, thanks to its compact size and easy-clean upholstery that holds up to everyday domestic use. Procurement teams should note the chair ships in knock-down packaging within protective 5-layer corrugated cartons with EPS foam corner protection, hardware kits, and printed assembly instructions. Simple assembly is required to attach casters, connect the gas lift, and secure the seat assembly. Load planning teams can reference standard container loading quantities for bulk orders, and select the available two-tone dark charcoal and light blue upholstery option to align with existing interior design palettes.
