The Superior mattress is where unparalleled quality and luxurious comfort meet. All of the components in this mattress work together in perfect harmony to give great support to ensure your best night's sleep. We start with our unique pocketed coil system, which is encased with a double row of very firm coils to give that full edge to edge sleeping surface. We then layer in multiple high density layers of support foam to give the mattress a base that will allow the comfort layers to perform properly. The Superior mattress is a true pillow top, which means it has an inner panel that separates the insulator and support layers from the comfort layers to keep the integrity of the comfort layers intact over time. The comfort layers in the Superior are unmatched. We combine our Copper gel-infused latex and a zoned micro-coil to give incredible comfort and support that allows your body to rest peacefully all night long.
