Customization Specifications for Suppliers

When contacting suppliers for custom sofa pocket springs, provide these key specifications:

Specification	Description	Considerations for 4" Sofa Cushion
Dimensions (L x W)	Exact length and width of spring unit	Allow 0.5-1cm margin less than interior cavity size for easy installation
Spring Wire Gauge	Thickness of steel wire (determines firmness)	For firm, supportive seats: 12-14 gauge (~2.0-1.6mm) resists sagging. Thinner wire = softer feel.
Spring Count & Density	Number of springs per unit area	Higher density provides precise contouring: 500-1000+ springs/m² for quality 4" sofa springs
Edge Support	Perimeter reinforcement method	Border wire or reinforced edge critical for preventing roll-off and stable seating edge
Firmness Zoning	Using different gauge springs in different areas	Ergonomic zoning: firmer springs in center (hip area), softer springs at sides and back
Connection Method	How pocket springs are linked	Ultrasonic welding or thermal bonding for stable unit that won't separate
