Get premium motion isolation with this Serta iComfort Blue Fusion 300 plush hybrid pillowtop king mattress. The TempActiv gel memory foam is infused with millions of cooling gel beads to help dissipate heat and keep the bed cool through the night, while the two layers of EverCool Fuze gel foam offer cushioned comfort and breathability. Sleep deeper with the plush quilt-covered Pillowtop that packs layers of PillowSoft HD and PillowSoft Foam.

This Serta iComfort Blue Fusion 300 plush hybrid mattress features the advanced Serta Hybrid Coil Support system. This base support layer includes high-grade spring coils wrapped individually in fabric casing for reduced motion transfer and optimized support. The Serta BestEdge Foam Encasement system prevents premature sagging by extending the rows of wrapped coils all the way to the edge of the bed. This system also hinders edge roll-off and extends your sleeping space.
