Product Description

This Off-White Diamond-Quilted Arm Three-Seater Leather Sofa delivers a refined, structured silhouette suited to elevated casual and formal settings alike. Its low block base supports a straight three-seat frame, with wide rolled padded arms trimmed in solid walnut veneer for subtle textural contrast. Diamond-quilted stitching defines the arm panels, while horizontal tailored stitching covers the base panel, creating a polished, cohesive visual profile. The tight fixed seat and segmented two-tier back cushions hold a consistent, tailored line, with a 10-degree fixed backrest angle that balances relaxed comfort and upright support. Each of the three individual seating positions offers a 250mm armrest rise from the seat surface and built-in lumbar contouring, aligning with a seat height of 480mm from the floor for easy, accessible seating. The sofa measures 2600 x 1000 x 910 mm when fully assembled, with 50mm of base clearance above the floor, fitted with hard plastic non-marking glides to prevent scuffing during repositioning. Built for long-term use, the frame uses 30mm kiln-dried hardwood with corner blocking for structural stability, supported by 8-gauge sinuous steel springs spaced 120mm apart beneath the seat. Contact surfaces use 1.4mm top-grain cowhide leather rated for 50000 abrasion cycles, while sides, back, and base panels use match-grade synthetic leather for consistent visual flow. Seat cushions are filled with 40 kg/m³ high-resilience polyurethane foam with 60% rebound rate, wrapped in 20mm polyester fiber, with arm panels padded with 10mm foam beneath the quilted stitching. Each seat supports a 150kg static load, with a total product weight of 87kg. The fixed non-reclining design does not include sectional connection hardware, operating as a standalone straight seating unit. It functions as primary seating for residential family rooms and formal living spaces, guest seating for executive office reception lounges, shared seating for luxury apartment common areas, and in-suite seating for high-end hotel and boutique accommodation. Coordinated layouts pair the sofa with matching leather armchairs and a coffee table for a unified seating group. Procurement teams should note the unit ships across 2 cartons with a packaged gross weight of 110kg, requiring 40 minutes of assembly per set. Regular care involves wiping leather surfaces with neutral leather cleaner to preserve the finish over time. Covers are non-removable, so routine spot cleaning as part of scheduled maintenance is recommended to retain the upholstery’s crisp, premium appearance.
