Key Features & Manufacturing Specifications

When discussing with manufacturers, these are the critical parameters to define:

Parameter	Specification & Importance for 4" Sofa Springs
Spring Height	4 inches (approx. 10 cm). This low profile is essential for fitting into sofa seat cushions without creating a bulky, overly high seating surface.
Wire Gauge	Typically between 1.8mm - 2.2mm. A thicker wire (e.g., 1.8mm) will feel firmer and be more durable. A thinner wire (e.g., 2.2mm) will feel softer. The gauge must be chosen to match the desired seat firmness.
Spring Diameter	Smaller than mattress springs. Often 38mm to 45mm. A smaller diameter allows for a higher spring count, which increases support points and enhances comfort.
Spring Count & Density	This is a major selling point. A high count is crucial for a sofa to prevent bottoming out. • e.g., A unit for a standard sofa seat (approx. 60cm x 60cm) could contain 144+ springs for premium support. • Density is expressed as springs per square meter (e.g., 400+ springs/m²).
Tempering	Mandatory. The springs must be heat-tempered to relieve internal stresses. This ensures they return to their original height after years of use, preventing sagging and maintaining support.
