To begin with, the Serta 12 Inch Pillow Top Mattress in a Box surrounds you with cloud-like luxury comfort the moment you lie down. A breathable pillow top quilt softens first contact, while Cool Twist® gel-infused memory foam pulls excess warmth away so hot sleepers stay relaxed. 

Next, a 3-Zone gel-foam band focuses extra lift beneath the hips, delivering targeted pressure point relief that side-sleepers praise as the Best 12-inch pillow top mattress for side sleepers. Deeper still, 805 Individual Advantage Wrap Coils form a dependable hybrid core—each spring flexes on its own, creating a soft pillow top mattress with pocketed coils that offers reduced motion transfer for couples.

Because Cloudy Mattress ships free nationwide and lets you finance through Affirm, it is easy to buy a Serta 12-inch pillow top online and upgrade to a Serta plush pillow top queen mattress or a spacious king while today’s sale lasts.
