The Rossa™ certified organic mattress is a customizable one-sided zipper-cover mattress. It features pocket-coil technology, encased in natural biodegradable materials, paired with a certified organic latex layer on the surface. Choose a split or solid latex comfort layer with firmness options in plush, medium, or firm. A sculpted surface is available at an additional charge to add pressure-point relief and increase air circulation, helping sleepers stay cool and comfortable. The pocket-coil springs are placed in a certified organic cotton encasement to prevent shifting over time. Covered in 10-oz. certified organic cotton on the bottom, the organic mattress is finished with our signature quilted woven cover.
