The most traditional type of mattress, standard coil mattresses derive their support from wire coils, or springs. The coils are attached with innerconnecting wires (often called helicals), which stabilize the coils and cause them to function as a single unit. Border wire is used to help a standard coil mattress retain its shape. The firmness and durability of a standard coil mattress is determined by the type of coil, the density of the steel wire, the number of helical wires and the coil count. We offer standard coil mattresses in all standard sizes, at price points to suit your budget.
