A Premium Comfort Adjustable Mattress

Superior Construction, Quality, and Technology

The Plush Comfort S9 is the best in our line of Plush Comfort mattresses that offer the ultimate in a smooth-top memory foam feel and adjustable comfort number bed technology. This bed provides a cooling sleep experience and includes a layer of gel-infused visco-elastic foam,  a 2″ layer of convoluted foam that maximizes comfort and contouring above the air chambers.  A support layer of foam below the chambers provides additional overall body support and support for all of the bedding components.   Each side of the bed is completely customizable through touch screen controllers that allow for 45 precise settings from 5 to 50.  The smooth-top cover is completely removable and professionally launder-able to ensure years of clean, comfortable sleep.  ​​​


The Instant Comfort®Flex-Head® mattresses come with split foam dual-adjustability.  Each sleeper can adjust their individual comfort settings on each side of the bed while maintaining the all-important cuddle zone™.
