The Supplemental Foundation Layer (or "SFL™") is a coconut coir mattress pad made of natural coir fiber, encased in GOTS certified organic cotton fabric. The SFL pairs well with your existing frame or foundation to help ensure additional and proper support of your mattress.

The SFL™ is recommended to be used with our REST line of mattresses as the coil springs used in most supporting box springs are approximately 3″ in diameter. Although many more pocket coils are used in the Rossa™, Clara Nouveau™ and Stella™ than are used in other mattresses, their diameter is closer to 1¼″. What this means is that to prevent the pocket coils from resting on an unsupported space, our SFL™ is required on all box springs and on wood slat foundations with spacing between the slats greater than 1″.
