Advanced Memory Foam revolutionizes the Beautyrest® experience.

The unsurpassed Pocketed Coil® spring technology of the Beautyrest® mattress meets the advanced performance of Next-Generation Advanced Memory Foam. Each model in the Beautyrest® NxG™ series features NxG™ Advanced Memory Foam for heat dissipation, quicker recovery and consistent comfort. The result is the ultimate Beautyrest® experience: NxG™ Advanced Memory Foam and Pocketed Coil® spring support working together to bring you night after night of blissful, undisturbed sleep.
 
Created in a special vacuum-sealed chamber to increase airflow and resilience, NxG™ Advanced Memory Foam
not only responds quickly to your movements, but
also helps dissipate heat to help keep you at your ideal
sleeping temperature.  

Another innovation that makes this mattress truly revolutionary in its combination of advanced features is the addition of the Evenloft™ top layer. Evenloft™ creates a smooth surface, allowing you to better feel the comfort layers and support.
