Support system descriptions

Power Coil
An engineered interconnected coil system designed to provide stable, consistent support across the mattress. The coil structure forms the foundation of the sleep surface, helping provide dependable support night after night.
Pocket Coil
Individually encased coils that can respond more independently to pressure across the mattress. This allows the support system to adapt more locally to the body while helping reduce the transfer of movement across the sleep surface.
Miracoil®
Serta's continuous coil support system, engineered to provide structured support across the mattress. Its continuous construction is designed to distribute load through the support system and provide a stable foundation for the comfort layers above.
Best of Both™
A hybrid support approach that brings together complementary spring technologies within one engineered support system. It is designed to combine structured underlying support with more responsive, individualised movement closer to the body.
Foam / No Coil System
A foam-based mattress uses its foam construction as both the comfort and structural foundation rather than a dedicated coil support system. Under Support First, this should be clearly distinguished from mattresses built around an engineered spring support system.
