Product Overview & Construction Details

The JINSLEI model OFS-LEA-311office reception sofa set is a coordinated 3+1+1 seating collection pred with a matching coffee table, finished in a rich dark brown leather aesthetic accented by polished walnut-stned hardwood trim. The set follows a formal, fixed conversational layout, with one three-seat sofa and two single armchrs positioned to face the centrally placed coffee table, creating a U-shaped arrangement ideal for guest interaction. Visual detls include uniform, high-tenacity polyester stitching along all upholstery seams, reinforced at high-stress corners, and smooth, grn-matched wood trim on armrest tops, corner accents, and furnishing feet for a cohesive, professional appearance. Seating units are built on fully welded 1.2mm powder-coated square steel tube frames to resist warping under regular commercial use, topped with layered padding: seat cushions use 45kg/m³ high-resilience polyurethane foam wrapped in a soft polyester fiber layer, while backrests use medium-density foam contoured for targeted lumbar support, segmented into individual user zones via vertical stitching on the three-seat sofa. Upholstery is commercial-grade smooth dark brown material, with exact leather or PU grade confirmed via supplier bill of materials. The matching coffee table features a 15mm MDF core with walnut veneer and solid wood edge banding, with a dual-level design offering an upper surface for beverages and materials, plus an open lower shelf for document and magazine storage. Non-slip felt pads on all seating feet protect hard flooring, while adjustable leveler feet on the coffee table prevent wobble on uneven surfaces. The fixed 105-degree upright backrest angle supports formal conversational posture, with no recline function to preserve a polished professional look, and permanently attached cushions mntn neat alignment in high-traffic areas. This set is well suited for executive office reception zones, corporate lobby wting areas, boardroom ancillary pre-meeting seating, government and institutional meeting spaces, and hotel business center lounges, as its formal finish coordinates seamlessly with dark wood executive and upscale hospitality interiors. For procurement, teams should note the full set ships across multiple protective cartons, requires two personnel for 45 minutes of on-site assembly to attach feet and arrange units, and has per-seat static load capacity rated for adult commercial use. Bulk orders can leverage optimized contner loading for standard international shipping, and buyers should confirm exact upholstery grade with suppliers prior to finalizing orders for high-traffic public installations.
