Comfort	Casper mattresses are specifically designed to sleep cool. We put a lot of R&D into how Casper mattresses perform throughout the night - like running thermal imaging tests and sweat tests. Our mattresses use a breathable comfort foam to offset the memory foam layered beneath it. This construction helps keep things nice and breezy and outrageously comfortable. Plus every mattress saves up to 57 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. This innovative cooling system is designed to help keep you cool all night. 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	We designed our own proprietary foam for our "just right" feel, and are now integrating those layers with resilient-yet-gentle fabric-wrapped steel springs. A firmer border provides edge support to help you get in and out of bed easily. Premium AirScape™ foam conforms to your body to relieve pressure. Memory foam with 3 areas of Zoned Support™ help align your spine and relieve pressure. Softer under shoulders and firmer around the hips, waist and lower back. 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.
