Not all pocket spring systems are created equal. The quality and feel depend on several factors:

Spring Count: The total number of springs in the mattress. A higher count (e.g., 2000+ for a King size) means more springs can work in a smaller area, providing more precise, detailed contouring and support.

Spring Height: Taller springs (e.g., 15-20cm) are often used for a plusher, deeper compression feel. Shorter springs (e.g., 10-14cm) can feel firmer and more supportive.

Wire Gauge: This refers to the thickness of the steel wire. A lower gauge number means a thicker, firmer spring (e.g., 13-gauge). A higher gauge number means a thinner, softer spring (e.g., 18-gauge).

Number of Coils (Turns): More coils (e.g., 5-turn instead of 4-turn) can make the spring more flexible and responsive, often contributing to a softer feel.

Zoning: Advanced systems use springs of different tensions (gauges) in different zones of the body (e.g., firmer under the hips, softer under the shoulders) to provide ergonomic support.
