Cool Action™ Dual Effects® Gel Memory Foam:
Serta’s latest breakthrough in gel memory foam technology is the world’s first dual-action gel memory foam infused with both Serta’s original MicroSupport® gel and our latest MicroCool+™ gel. Millions of gel beads gather under the areas of your body that need extra support while also helping the mattress dissipate heat away from the sleep surface.
Duet® Coil Individually Wrapped Coil-in-Coil Support System:
This exclusive support system features strategically placed Duet® Coils that properly balance comfort and support across the entire sleep surface, allowing the system to respond to each sleep partner individually. Each Duet® Coil is engineered so the exterior coil provides an initial soft and luxurious feeling, while the interior coils provide the essential support needed for correct postural alignment. Plus, our Duet Coil Support System features a posturized design, with nearly two-thirds of the Duet Coils concentrated in the center third of the innerspring.
