Eastman House's Patented Lifedge Perimeter Support technology provides greater edge support around the entire mattress perimeter for ultimate sleep comfort and quality.

Lifedge inserts steel butterfly spring supports into our foam encased rail border. This extends the life of the mattress by eliminating soft, sagging edges while also increasing the sleeping surface with its edge to edge protection system.

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.

The Patented Zoned Quilt Support System pre-compresses the cushioning materials in the center third section of the sleep system to eliminate mattress breakdown and strengthen the section in which body impressions most commonly occur.

Back pain, stiffness, and discomfort are most commonly associated with the center third or lumbar region of the mattress. Eastman House's Zoned Quilt technology implements an additional layer of visco-elastic memory foam within the fortified quilt region - providing extra pressure point relief together with supreme comfort and support.
