The iComfort Directions Inception model features 4 exclusive technologies to balance comfort, support and temperature regulation. It starts with our new Thermo°Cool™ yarn fabric cover with TENCEL® fibers, an exceptionally soft material designed to help improve heat and moisture flow at the sleep surface. Beneath this layer is our new EverCool™ Gfx Memory Foam, the world’s first premium, breathable memory foam featuring an infusion of super heat-conducting graphene material for supple, body conforming comfort and an extra ability to whisk heat away from the body. Next, our breakthrough Cool Action™ Dual Effects™ layer helps provide more support where your body needs it and an enhanced ability to transport heat away from the mattress layers above it. Finally, our Pods™ gel-activated support layer works with our Comfortlast® Foam core to help provide extra support from the deepest parts of the mattress and a firmer seating edge. Pair the Inception model with the new Serta® Motion Custom™ Adjustable Foundation, the most advanced adjustable base you can buy today. Featuring 9 all-new features, the Serta Motion Custom base allows you to personalize your bedroom experience like never before. Or, choose our standard flat foundation, which is beautifully finished to complement the look of your iComfort Directions mattress.
