The Perfect Sleeper Elite Foam Merriam II mattress features multiple layers of breathable gel foams, bolstered by a premium all-foam core and a layer of extra firm support foam. These layers work to deliver body-contouring comfort on top, while the layers below give you deep-down support.
Cool Twist® Gel Memory Foam: This unique design features cooling gel swirled into premium memory foam. This breathable memory foam helps enhance airflow and heat dissipation for a feeling that can only be described as a cool, contouring type of comfort.
Serta Support Foam: This extra firm foam helps provide a firm yet supportive feeling throughout the mattress.
Serta ComfortLast® Support Core with Ultimate Edge® Foam Encasement: A dense, premium, all-foam support core featuring high-firmness foam sides for strengthened edge support and reduced late-night ‘roll off’.
