Support	Up to 2000 of our patented, cone-like springs offer superior body support and increased airflow through your mattress. With up to 900 pocketed springs, engineered to offer 5 zones of targeted support for areas such as hips and shoulders.	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.
