The Serta iComfort collection is made up of all-foam mattresses and hybrid mattresses. The iComfort Foam mattresses utilize the Serta Foam Core in place of an innerspring support system. This dense foam core offers good-quality back support to ensure proper sleep posture for a comfortable, rejuvenating sleep.
The iComfort Hybrid mattresses have a 1025 iComfort Hybrid Support System, which uses individually wrapped coils to add responsive support under the pressure-relieving layers of memory foam.
Each iComfort mattress features Carbon Fiber Memory Foam, which serves several purposes. It relieves pressure and the carbon fiber adds a supportive strength to the foam. It also regulates temperature, as the carbon fiber draws heat away from your body.
As you go up the line, you'll notice there are more snowflakes stitched on the front of the mattress. These represent how many levels of cooling there are in the mattress. These layers include the Carbon Fiber Memory Foam previously mentioned, EverCool Fuze Gel Memory Foam, a cooling cover, and more variations.
