Let's look at the different types of mattress support options.

INNERSPRING MATTRESSES
An innerspring mattress is made with a steel coil innerspring support system, with various foams and fibers on top to provide comfort at the surface. Serta offers a variety of innerspring constructions, including our Continuous Support® innerspring and our most advanced Duet™ Coil Individually Wrapped Coil-in-Coil innerspring.
DID YOU KNOW?
The number of coils in a mattress varies from manufacturer to manufacturer and is based on a queen-size mattress (i.e. twin mattress have fewer coils, kings have more); but the coil count is not necessarily as important as the construction, and Serta’s unique coil construction achieves greater comfort and support.

MEMORY FOAM MATTRESSES
A memory foam mattress features an all-foam support core that works to balance proper support with pressure-relieving comfort. The top layers of the mattress include memory foam, as well as other comfort foams and fibers. Only Serta offers its exclusive Cool Action™ gel memory foam for enhanced cooling comfort and more support where you need it most, in our iComfort® gel memory foam mattresses.

MEMORY FOAM HYBRID MATTRESS
A memory foam hybrid mattress combines the support of a traditional steel coil innerspring with the comfort of memory foam. Serta's memory foam hybrid mattresses feature Serta's innovative iSeries® technology. This technology features Serta’s Cool Action™ Gel Memory Foam and Serta’s Duet Coil Individually Wrapped Coil-in-Coil Support System, for a fully supported and deeper sleep.
