The Applause Plush combines the benefits of Serta's revolutionary Cool Action™ material with the feel of a traditional plush mattress. Our exclusive Cool Action Gel Memory Foam provides cradling and cooling comfort, while a layer of Serta® Comfort Foam gives the bed a soft yet supportive feel at the sleep surface. Plus, our Duet™ Coil Individually Wrapped Coil-in-Coil System responds to each sleeper individually to provide the essential support needed for correct postural alignment.
