Micro-Coils Serta® All
Micro-coils are small coils used in the comfort layers, above the main support. They add bounce and airflow close to the surface and respond to small movements, giving a lighter, more lifted feel than foam alone.
Serta mattresses balance comfort and support with cooling-gel foams and proven coil systems, from a name trusted in Canadian bedrooms for decades. Compare every option below by feel, size, and price.
