The Comfort Solutions Signature Collection 100/90 has been expertly designed and crafted using real-time data from the exclusive Comfort Solutions Lab®. This mattress is designed to perfectly suit individuals with the Comfort Solutions Sleep Code 100/90. The mattress features a stable and well-designed support capsule which contains edge-to-edge pocket spring units to create a larger sleeping surface, made to support your body. Atop the foundation sits a combination of foam layers inside a removable comfort capsule. This enables you to easily remove and rotate the capsule for even wear. The combination of foams has been carefully selected to relieve specific pressure points, reducing tossing and turning and resulting in restful sleep.
