Product Description

The LINGKEN WF-CONF-ARM-001 fixed office conference armchair blends traditional formal styling with robust, purpose-built construction for professional seating applications. Its visual profile features a streamlined walnut-stained bentwood frame that forms a cohesive structural base, paired with integrated curved bentwood armrests finished to match the frame, creating a unified, polished silhouette. Warm brown upholstery wraps the contoured seat and backrest, complementing the rich wood tone to deliver a refined, professional presence suited to formal spaces. The chair’s core structure relies on stained solid bentwood assembled with mortise and tenon wood joints reinforced by metal dowels, plus a center rear support leg for added frame rigidity. Internal seat support comes from bent plywood, with a high-density polyurethane foam seat core and medium-density molded polyurethane foam back core encased in 1.2mm thick brown split leather and PU leather upholstery. Non-marking, non-slip black rubber glides cap the four-leg base to protect hard flooring surfaces from scuffs and scratches, while keeping the chair stable during stationary use. Key performance attributes include a 26kg net weight, recommended static user load of 150kg, 50kg/m³ seat foam density, 35kg/m³ back foam density, 45% foam rebound rate, and upholstery abrasion resistance rated for 50000 double rubs, with seam stitching set at 8 stitches per inch for consistent durability. Designed for fixed upright seating with an integrated contoured lumbar support, the chair supports a stationary use posture, with a 125-degree recline angle across 3 suggested lock positions for gentle positional flexibility without full adjustability. It is well suited for formal boardroom fixed seating arrangements, visitor reception waiting areas, guest seating opposite executive desks in private offices, and permanent training room setups for long-duration seminars and sessions, with a recommended pairing with 2.4m executive desks, and rated for 8 hours of daily use pending ergonomic confirmation. Procurement teams should note each unit ships across 2 cartons, with a 40-minute per-set assembly time, and that 135 sets fit in a 20GP container at 85% space utilization, to support accurate freight and installation planning.
