Fusion 300 PT King Mattress by Serta

The Fusion 300 PT King Mattress supports and comforts your body as you sleep. The EverCool Fuze Gel Memory Foam helps your mattress by reducing heat buildup and promoting airflow as the edges of the mattress are extended with the BestEdge Foam Encasement that prevents roll-off too. The TempActiv Gel Memory Foam provides both comfort and support while also dissipating more heat away so you remain cool every night.
