Removable Back Cushion Component – Furniture Manufacturing

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

Frequently Asked Questions

How do I clean a removable back cushion?

Remove the cushion via zipper or fasteners, spot clean with mild detergent and water, air dry completely before reattaching to prevent mold or damage.

Are these cushions interchangeable between sofa brands?

Typically not; cushions are designed for specific modular systems due to variations in dimensions, fastener types, and foam specifications. Check manufacturer compatibility guides.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
