Coil Count: This refers to the number of springs in the mattress. Generally, a higher coil count means more individual points of support, allowing for better contouring and less motion transfer. However, coil count should be considered alongside coil gauge and design.

Coil Gauge: This measures the thickness of the steel wire. A lower gauge number means a thicker, firmer coil (e.g., 12-gauge). A higher gauge number means a thinner, softer coil (e.g., 18-gauge). Manufacturers often use a mix of gauges in different zones of the mattress.

Zoned Support: Advanced pocket spring units are often zoned.

Firmer zones (with thicker-gauge coils) are placed in the center third of the mattress to support the hips and lumbar region, preventing the body from sinking in too deeply.

Softer zones (with thinner-gauge coils) are placed under the shoulders and legs for better pressure relief. Common configurations are 3-zone, 5-zone, or even 7-zone support.

Height of the Coils: Taller springs tend to have a greater range of motion and can be softer, while shorter springs are often firmer and more responsive.
