The natural TencelTM in our premium cover is more absorbent than cotton, softer than silk and cooler than linen, improving moisture wicking and natural hygiene. Alternating offset coils provide increased support, reduced roll off and promotes better comfort, support and alignment than traditional coils. Comfort and support foams are crushed to minimize the initial softening and lock in the comfort, to feel like new longer. Coils systems are encased in foam to provide more sleeping surface and improve the edge support. Specifically designed to articulate on adjustable beds to customize your sleep experience.
