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”.
