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. |
