Comfort	A top layer of memory foam helps reduce the amount of movement from your sleep partner. The Soft model reduces a bit more motion transfer than the Firm model.

The Nuvanna mattress is a multi-layer foam system designed to provide fantastic sleep for a healthy, balanced life. We believe that body wellness and tranquility begins with an exceptional night's sleep, and we design our mattresses to provide your mind and body with the rest you need to enjoy the highest quality of life imaginable. Our top layer is filled with innovative, phase-change gel particles that disperse heat to keep you at the ideal sleeping temperature. It's soft, provides comfort and minimizes pressure points. Our middle layer isolates sleep movements so that you feel continuous support and comfort without feeling every move your partner makes. It's our transition layer of viscoelastic foam so that you don't wake up.
Support	Our high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you. Support Foam base layer engineered to be highly durable and resilient. We've tested it, and we know it bounces back every time.	Our mattresses are made out of three distinct layers designed to perform different functions but together offer a supremely comfortable and supportive sleeping surface. Our base layer eliminates the quicksand, sinking feeling that plagues other foam mattresses. Because it supports the other two layers to keep your spinal cord aligned, you'll feel suspended and supported at every moment.
