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.

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).
