Product Details

This Firm Perfect Sleeper mattress is made with Serta’s exclusive 520 Continuous Support Innerspring, which combines our continuous coil design with our Head-to-Toe Coil Construction to promote proper back support and undisturbed sleep. Rows of continuous coils run head-to-toe, with each coil attaching to its neighbor, for the durability and stability needed to provide support while absorbing motion.

This mattress also features Serta’s PillowSoft Foam, an extra soft foam that gently contours the body to provide enhanced cushioning and pressure-relieving comfort, which can help reduce tossing and turning. It also features Serta’s Pillo-Fill, which is designed to enhance both airflow and moisture wicking at the sleep surface. Together, these properties can help promote a balanced sleeping temperature.
