iComfort EFX Aura
is the entry-level model in the iComfort EFX
collection of memory foam mattresses
The 9" high iComfort EFX Aura
has a firmness level of Plush. support is provided by the Comfort Last Foam Core
of high resiliency foam
. This underlying support is augmented by the Ultimate Edge
perimeter support, which holds the layers in place while supporting the sleeping surface.
The EverFeel Technology
begins at the top in the cover
fabric which blends polyester
, lycra and Tencel. Tencel is fibers derived from wood pulp which wick moisture and cool the sleepng surface through evaporation.
The main comfort feature is Serta
's Cool Action™ Dual Effects Gel Memory Foam
. It is open-cell memory foam
infused with two kinds of gel
gel is selected to make the memory foam more supportive while still being conforming, and MicroCool+
gel is for cooling.
The primary role of the Cool Action
™ Dual Effects
gel memory foam is pressure relief. Memory foam responds to weight and heat to conform to the sleeper's body contours, evenly supporting the entire body. Since a few parts of the body don't bear all the load, this reduces pressure points.
Since ordinary memory foam builds up heat, manufacturers find ways to counteract it. One way, used by Serta iComfort
, is open-cell structure. This allows air to flow through the foam. A second method is infusing the memory foam with gel. Gel carries heat away to where it can dissipate. Serta
claims that its method of infusion is better than the way discount-price manufacturers do it.
The Aura EFX
has the same 25-year warranty as the other iComfort EFX
models. It is also at least as widely available as they are.
