If you enjoy the feeling of a memory foam mattress but desire the adjustability of an air-supported system, the Plush Comfort S7 is a great, moderately-priced bed that provides a luxurious sleep experience.  The patented smooth-top cover sleeps cooler than most quilted top mattresses, and its zippered panel gives you access to the comfort compartment.  Here is where you will find CertiPUR-US^® Certified Convoluted Comfort Foam layer and a Ventilated ThermaPhase™ Gel-Infused Visco memory foam layer which makes rotating the foam layers for longer life much easier.  These foam layers contour above the air chambers that can easily be adjusted anytime with 45 unique number settings from 5 to 50.  The Plush Comfort  S7 bed comes with split foam, giving each side of the mattress its own customized comfort layers that can be easily upgraded or replaced at anytime.
