Comfort
Cooling helps keep you at the right temperature for your best. Two layers of perforated breathable foam help reduce heat. Plus every mattress saves up to 70 recycled bottles from the environment. A top layer of proprietary perforated breathable foam helps reduce heat, the tiny holes move hot air and body heat away. With a thin coating of cooling gel that adds a refreshing feel. This innovative cooling system is designed to help keep you cool all night. Second layer of AirScape™ helps prevent overheating. These air channels allow heat to escape. Resilient springs increase airflow.
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
Superior plushness without sacrificing support. More support where you need it most with the plushness you crave. Zoned Support™ Pro offers 7 zones of targeted support for healthy spinal alignment, softer foam around the shoulders provides more relief to the upper body and multiple ergonomic points under shoulders, hips, waist and lower back. A firmer border provides edge support to help you get in and out bed easily. Premium AirScape™ foam conforms to your body to relieve pressure. This has a plush, velvety soft feel. A second layer of supportive foam has 3 ergonomic zones to help align your spine and provide more relief. A third layer with Zoned Support™ Pro relieves pressure under the shoulders, and provides more support under the waist, lower back, and hips to align your spine. These zones reinforce support from the layers above. Fabric-wrapped springs provide active support and a little lift.
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.
