The Edge Signature is a complete sleep system, engineered by the same topper specialists who've spent years perfecting comfort layers. This 14" mattress pairs a dense, stabilizing foundation with a fully removable 3.5" Replacement Comfort Layer— the one part of a mattress that actually wears out is the only part you'll ever have to replace.

As your sleep needs change through the years, the Edge Signature adapts with you, delivering lasting comfort at every stage of life.
