Support Info The OkiSoft's high-density gel memory foam allows you to sink into its depths while still getting all the support and pressure relief that OkiOki's memory foam provides. Multi-layered foam technology adds support, resilience, and temperature regulation for the coolest, most comfortable sleep ever. The various blend of ingredients deliver the perfect amount of body contouring and pressure relief with extra soothing support. The Infinity Foam top layer is our unique material that prevents heat retention for a cooler night's sleep, and gives the perfect balance of support, contouring, and pressure relief in all the right places. This is our finishing touch to give you an unparalleled indulgent experience.
Comfort Specs Cloud-Like Comfort: A combination of soft and porous layers of memory foam will cradle your body without creating heat or causing you to sink too deep into your mattress. Every iComfort mattress is made with our exclusive Carbon Fiber Memory Foam. This system channels heat away from your body.
Gel Active® Max Foam (used only in CF2000 model) is an open celled memory foam helps promote airflow, so you don't have that hot, stuffy feeling when falling asleep.
UltraCold System™ (used in the CF3000 and CF4000 models) The layer of extra-cool Carbon Fiber Memory Foam is engineered to work hard at absorbing excess heat from your body, then channel it away, all while you sleep comfortably.
Our unique foam construction provides contoured support & breathability for the coolest night's sleep.
Support Specs Memory Foam Core: The gel memory foam contours to your body without causing excessive sinking, while providing the proper support needed for a great night's sleep. Carbon Fiber Memory Foam provides exceptional strength for back and neck support.
Air Support™ Foam (used only in CF4000 model) moves with your body and contours around it to help alleviate aches and pains caused by pressure points.
Our edge-to-edge pocket coil system was created to provide superior edge support. Each coil is individually wrapped so it can compress and expand independently, providing you with pressure relief where you need it most. The coils are positioned between layers of foam to allow you to feel like you're floating on air.
Fabric Specs Ice Yarn Zip Cover. This hypoallergenic cover is cool to the touch to help regulate body temperature and prevent you from overheating. The cover is easy to remove and machine washable. A Max Cold™ Cover is used in the CF3000 and CF4000 models. Made from super cool high-performance fibers for an instant cool-to-the-touch sensation.
