The GOLS certified Supplemental Foundation Layer is made of natural coir fiber and encased in GOTS certified organic cotton fabric.

The coil springs used in most supporting box springs are approximately 3” in diameter. Although many more pocket coils are used in the Rossa™ and Stella™ than are used in other mattresses, their diameter is closer to 1 1/4”. 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”.
