How Many Coils Should a Mattress Have?

Recommended Coil Count

The number of coils a mattress should have depends on the size of the mattress and the gauge of the coils. Heavier gauge coils typically provide firmer support with less coils. That said, an innerspring mattress of any size should have several hundred coils. Innerspring mattresses are often rated by the number of coils used in production, but there are many other factors to consider on top of coil count when purchasing a new mattress.
