  Conforming comfort foam adapts to your body to reduce pressure at the shoulders, hips, and lower back while maintaining a firm, supportive feel.
• Contour Pro Individually Encased Coil System
  Pocketed coils respond independently to movement, reducing motion transfer and providing targeted support where your body needs it most.
