What makes iComfort technology better than ordinary memory foam?

Serta’s Cool Action Gel Memory Foam is designed to feel like traditional memory foam….only better! What makes our Cool Action material different is the MicroSupport gel, which is infused into premium memory foam to create an extremely comfortable, more supportive and cooler sleep surface.

Supperior 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.

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 and not support your entire body, Serta’s Cool Action Material contains millions of MicroSupport gel beads that work to provide extra support where your body needs it most.

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.

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.
