The Comfort Solutions Signature Collection 100/30 is an expertly crafted mattress designed in conjunction with data from the exclusive Comfort Solutions Lab®. This mattress has a removable comfort capsule composed of plush layers of specifically designed foam that will relieve your pressure points and an edge-to-edge pocket spring system. This ensures that every single inch of the mattress has adequate support. The full pocket spring unit is reinforced along the edges, contributing to responsive spinal support, zero motion transfer and larger-than-life sleeping surface. The benefits of a removable comfort capsule are that the capsule can be easily rotated for even wear.
