Component Specifications

Definition
A detachable upholstered cushion component specifically engineered for modular sectional sofa systems, providing lumbar and upper back support while allowing for individual removal for cleaning, replacement, or reconfiguration. This component typically features a foam core with varying density layers, wrapped in fabric or leather, and secured with hidden fasteners or zippers to maintain structural integrity during use.
Working Principle
Works by distributing body weight and pressure through multi-density foam layers to reduce fatigue, while the removable design utilizes hook-and-loop fasteners, zippers, or magnetic connectors to allow detachment without tools, enabling modular flexibility and maintenance access.
Materials
High-resilience polyurethane foam (HR foam) with density 30-50 kg/m³, wrapped in fire-retardant polyester fiberfill, covered with durable fabric (e.g., polyester, cotton blend) or genuine/synthetic leather, with reinforced stitching using nylon thread. Fasteners: YKK zippers or industrial-grade hook-and-loop strips.
Technical Parameters
  • Weight 2-4 kg
  • Dimensions Varies by module (typical: 50x60x15 cm)
  • Fire Rating BS 5852/CA TB 117
  • Foam Density 30-50 kg/m³
  • Fastener Type Zipper/Hook-and-loop
  • Load Capacity Up to 150 kg static
Standards
ISO 2439, ISO 3758, DIN 68880
