    Overview

    Feeling renewed every morning is as simple as snuggling into your Serta® Azure Bay 12” Medium Mattress every night. With an additional inch of thickness over earlier models, this mattress uses a combination of foam, gel foam, coils and fabric to create the right feel for a wide variety of sleepers—and is a great choice for those who share a bed.


    Plus, layers of PillowSoft™ and PillowSoft Aire™ Medium Comfort Foam provide the medium feel for a dreamy sleep in any position. Cool Twist™ Gel Medium Comfort Foam supports all shapes and boosts the breathability factor of the stretch-knit cover and the breathable underlayer to keep hot sleepers comfy.
