Product description from Serta:

Introducing the new iComfort Sleep System by Serta, featuring our Cool Action Gel Memory Foam - the world’s first memory foam infused with the support and cooling touch of Serta’s MicroSupport gel. This revolutionary new memory foam is designed to deliver superior pressure relief and more targeted support while sleeping cooler than ordinary memory foam. Plus, it is antimicrobial and dust mite resistant to help protect your mattress from potential allergens.

What makes iComfort technology better than ordinary memory foam?

Superior Pressure Relief
Too much pressure build-up while you sleep can cause disruptive tossing and turning. Serta’s Cool Action material is uniquely designed to deliver lower average body pressure than other advanced comfort materials. This means that you can get a deeper, more restful sleep with less tossing and turning.

More Support Where You Need it Most
Your body needs proper support while you sleep so your muscles can relax and rejuvenate. While ordinary memory foam can sink in too much, Serta’s Cool Action Material includes millions of MicroSupport gel beads which gather in areas needing extra support, providing support where your body needs it most, and allowing you to wake up with fewer aches and pains.

Sleep Cooler
Heat build up during the night can cause uncomfortable and restless sleep. While ordinary memory foam can trap heat against the body, Serta’s Cool Action material combines an open cell structure and our MicroSupport gel to dramatically increase airflow and actually whisk heat away from the body. In fact, it is up to 12 times more breathable than ordinary memory foam.

Unchanging Comfort
An ordinary memory foam mattress can require a lengthy “break-in” period before it feels as soft and comfortable as it did in the showroom. Serta’s Cool Action material is engineered to deliver exceptional comfort from day one. Plus, our material is designed to maintain its pressure-relieving comfort through a wider range of home temperatures than ordinary memory foam.

Additional Features (available in all iComfort models)

ComfortLast Foam Core with Ultimate Edge Support
This advanced foam support system is built to be extremely durable -- so you get the support you need night after night. Ultimate Edge Support reduces edge “roll-off” effect, so you have more room to stretch.

StabL-Base Foundation
Serta’s StabL-Base Foundation is designed to enhance the performance and appearance of every iComfort Sleep System, providing consistent support and helping to isolate the impact of your sleep partner’s movements.

Optional Features (available in select iComfort models)

KoolComfort Memory Foam
This latest generation of Serta’s exclusive and breakthrough KoolComfort Memory Foam gently cradles and conforms to the body at the sleep surface, creating a softer yet supportive feel while promoting a cooler sleep surface.

Cool Reaction Slow Recovery Latex Foam
Unlike other more "springy" latex foams, Serta’s exclusive Cool Reaction Latex foam is designed to recover more slowly like memory foam. Plus, latex is naturally breathable and hypoallergenic, keeping you cooler while helping to protect your mattress from dust mites.
