Eastman House's Patented Spinal Zone Sleep System is clinically proven to reduce back pain for a healthier night's sleep.
Traditional innersprings are framed with the use of a border rod. Spinal Zone uses an additional, slightly lighter border rod which attaches to the center third section of the spring unit. This exclusive technology reinforces the center-third section of the mattress: providing enhanced back support.
The Patented Spinal Zone Sleep System works in conjunction with our Patented Zoned Quilt Support System. Together, the two technologies provide the ultimate sleep experience while still maintaining a superior level of comfort.
