What is a Coil Gauge?


A coil gauge is a measurement of the thickness of the coils inside an innerspring mattress. A mattress typically measures between 12 and 15 gauges. A higher measurement means the coils inside a mattress are softer and thinner while a lower gauge indicates firmness. If you're looking for a mattress with a firm comfort level, its coil gauge is usually 13 or lower. This data also can help determine a mattress' durability. Lower gauges indicate that a mattress is more likely to last longer than one with higher gauges.
