Design & Build
The Serta Five Star Mattress Tranquility features a 9-layer hybrid construction that combines pocketed coils with multiple foam types. The foundation consists of durable pocket springs that provide responsive support while minimizing motion transfer between sleep partners. Above this coil system, layers of memory foam, PillowSoft Aire Foam, and ActivBalance Support Foam work together to offer contouring comfort and pressure relief. A distinctive feature is the 3-zone support foam that specifically targets the lumbar and hip areas, with an additional gel foam lumbar support band for enhanced lower back alignment. The top layers incorporate Cool Twist Gel Foam designed to enhance airflow and dissipate heat. The mattress measures 14 inches thick with a firm feel profile, featuring a tight-top design that provides a uniform sleeping surface without additional pillow-top padding. The blue polyester cover offers a clean, simple aesthetic that works with various bedroom décors.
The mattress arrives compressed in a box, making delivery and setup straightforward. Once unboxed, the mattress needs time to fully expand to its 14-inch height. The hybrid construction combines the durability of coils with the contouring properties of foam, aiming to provide long-lasting support. The materials are CertiPur-US certified, ensuring they meet specific standards for content, emissions, and durability. The pocketed coil system helps isolate motion, which can benefit couples by reducing sleep disturbance. The firm feel is achieved through the combination of supportive coils and firmer foam layers, designed to minimize excessive sinkage. The mattress is manufactured in the USA with global components and comes with a 10-year limited warranty. Cleaning typically involves spot cleaning the polyester cover, as the mattress is not designed to be fully immersed in water or machine washed.
Performance
The Serta Five Star Mattress Tranquility is designed to deliver firm support with targeted pressure relief. The 3-zone support system focuses on the lumbar and hip areas to help maintain spinal alignment, particularly beneficial for back and stomach sleepers. The hybrid construction combines the responsiveness of pocketed coils with the contouring of multiple foam layers. The cooling gel foam technology aims to enhance airflow and dissipate heat, which can help prevent overheating during sleep. The firm feel provides a supportive surface that minimizes excessive sinkage, promoting proper sleeping posture. The pocketed coil system helps reduce motion transfer, which can lead to less disturbance when a partner moves during the night. The mattress is designed to provide durable support that maintains its shape and performance over time.
The pressure-relieving foam layers work to distribute body weight evenly and reduce pressure points. The combination of memory foam and specialized support foams aims to offer both comfort and stability. The bed-in-a-box design makes initial setup convenient, though the mattress requires adequate time to fully expand after unboxing. The firm rating indicates it may feel too firm for side sleepers or those who prefer a softer surface. The cooling properties depend on the gel foam's ability to enhance airflow within the mattress layers. The hybrid construction typically offers a balance between the bounce of springs and the contouring of foam. The mattress weight of approximately 123 pounds for the king size requires careful handling during setup. The 100-night trial allows users to test the mattress's comfort and support in their own sleeping environment.
