Using organic cotton fibers and Nanobionic® Technology, the Zephyr Mattress transforms your natural body heat into regenerating infrared rays. The benefits of infrared rays on the body are widely recognized. It's been proven that they are very beneficial in the energetic and restorative processes of the human body. This advanced technology allows you to recover better, especially after heavy physical exertion. You'll wake up recharged and feeling great! Using GelFlex Plus, our premium memory foam topper is infused with gel particles. It cools you down when you're hot, and warms you up when you're cold. Breathable Hybrid Foam helps to regulate your body temperature. Our antimicrobial technology in the Antimicrobial Foam layer helps to reduce bacteria growth, and works as a protective shield against allergies.
Support	Choose our soft layer for a cozier, more "in-the-bed" feel. Choose our firm layer for a sturdier, "on-the-bed" feel. Engineered to be highly durable and resilient. We’ve tested it, and we know it bounces back every time.	The integrated support frame keeps your mattress from flattening when you sit on the edge, and reinforces the structure. This allows you to sleep right on the edge - maximizing your mattress surface. Targeted Zone Support: Your shoulders and hips need a different level of support, so we've adapted the density of our foam according to these areas of your body. Our foam is softer on the shoulder zone, to reduce the pressure felt from day-to-day activity. The hips and torso zone features firmer foam which provides better alignment for your spine.
