With the Cooling Copper ADAPTIVE® Hybrid King Mattress, you can invest in something that hits all the marks for fantastic sleep (and that investment is surprisingly reasonable). From moisture-wicking technology to enhanced pressure-relief and foam that keeps you cool and clean, this premium design has it all. It begins with a moisture-wicking ADAPTIVE® cover that dynamically responds to any excess heat and perspiration, so you stay cooler, dryer, and soundly asleep. Beneath its surface, copper-infused memory foam adds an extra layer of insurance against hot nights by drawing heat away from your body so you stay cool all night long.Your mattress will stay smelling fresh and less like lingering odors, thanks to its natural green-tea infusion. This ingredient-rich foam layer is supported by a base layer of individually wrapped supportive springs that benefits you in more ways than one. These durable coils effortlessly hug your spine and joints in custom comfort while also keeping your sleeping partner’s tossing and turning away from your side of the bed. And for those that struggle with sitting on the edge of the bed or getting in and out, the ADAPTIVE® hybrid is encased with a perimeter of thick foam to increase stability and prevent sagging. Like all our mattresses, it’s expertly rolled and packed into one convenient box that ships right to your door. On top of a mattress that’s this adaptable, it’s hard to imagine there’s anything left that could disturb your sleep. That’s why we recommend going with the thing that’s not so hard - dozing off in record time.
