Technical Features
Spring Count (Number of Coils)
The total number of individual pocket springs in the mattress. Generally, a higher coil count indicates the potential for more precise support and better contouring, as the pressure is distributed over more points.
- Typical Range: Can range from around 600 in a budget-friendly queen size to over 2,000 in a high-end model. For a queen mattress, a good benchmark is 1,000+ coils.
Important: Don't look at coil count in isolation. The quality of the steel, the design of the coil, and the comfort layers are equally, if not more, important.
Coil Gauge (Thickness of the Wire)
The thickness of the steel wire used in the springs. The lower the gauge number, the thicker and firmer the wire.
- Low Gauge (e.g., 12-13): Thicker wire, firmer feel, more supportive for heavier weights.
- High Gauge (e.g., 15-18): Thinner wire, softer feel, more conforming.
- Many mattresses use a mix of gauges in different zones for targeted support (e.g., firmer coils in the center third for the hips).
