To begin with, the Serta iComfort Elana Firm Mattress surrounds you with a CoolFeel™ breathable fabric that draws warmth away the second you lie down, giving you a heat-wicking cooling sleep surface ideal for hot sleepers.

 Next, graphite-infused memory foam combines with gel-charged comfort layers to create firm contouring that many reviewers rank as the best firm mattress for stomach sleepers seeking a stable feel without harsh pressure. 

Because these foams rest on a 5-Zone Response support system, you receive optimal spinal alignment support right where the shoulders, lumbar, and hips need it most. Moreover, high-density core foam absorbs excess movement, producing reduced motion transfer for couples so partners rest undisturbed. 

Finally, Cloudy Mattress lets you buy Serta iComfort Elana online with free shipping in the USA, fast one-to-two-week delivery, and easy financing—making an upgrade to an 11.5-inch firm memory foam mattress effortless while the $700 Memorial discount lasts.

Designed for deep comfort and better rest, so you wake up refreshed and ready for the day

Cloudy lists this model as Firm Comfort, offering minimal sink and strong push-back that many back- and stomach-sleepers prefer.

The 5-Zone Response layer lifts the lumbar region while cushioning shoulders and hips, helping many users wake with less stiffness.

No. Any solid platform, slatted base with gaps under three inches, bunkie board, or adjustable bed will provide proper support; a traditional box spring is optional.

The knit cover contains heat-dissipating fibres that work with graphite-infused foam to pull warmth away from the body, maintaining a cooler sleep environment.

Queen: 60″ W × 79.5″ L × 11.5″ H. Other sizes mirror standard U.S. widths and lengths listed above.
