Definition of Continuous Coil

Meaning of the Term as it Pertains to Mattresses

What is a Continuous Coil?

A continuous coil represents an innerspring coil construction in which each row consists of a single curved wire. The S-curved construction of a row simulates a coil by contracting as weight is applied. Rows bind together to create one continuous support system in which each "spring" draws support from its neighbor.

Mattresses with continuous coil constructions generally hold their shape longer than those with traditional coil constructions. The sturdy mattress design usually features extra comfort layers, which relieve most of the pressure from the top layer. The continuous coil structure below maintains spinal alignment by supporting the heavier portions of the body from sinking too far down. Production for continuous coils costs less than standard coil production, which makes the type popular with value-seeking mattress shoppers.
