The Serta Serene Sky 12" Firm Mattress is made of Cooling gel foam combined with individually wrapped coils for comfortable support night after night. This quality firm mattress combines Cool Twist® Gel Foam, designed to promote airflow and heat dissipation, with the contouring and cradling support of individually wrapped coils so that you experience blissful sleep. The additional 1” of cooling gel swirled directly into breathable foam designed to promote airflow and heat dissipation.
The 825 individually wrapped coils provide consistent, durable support, while an extra-deep foam rail helps reduce edge roll-off and extend the sleep surface. The Pillow Soft Aire®, an extra-soft foam, gently contours the body for enhanced cushioning support and promotes airflow through a unique rippling design. Rest assured knowing all the Serta Serene Sky mattress models are designed and assembled at one of Serta’s state-of-the-art facilities in the USA.
