The Stella™ is a one-sided organic mattress available in three firmness options: plush, medium, or firm. It features pocket-coil technology, encased in natural biodegradable materials, paired with a certified organic latex layer on the surface. 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 mattress is finished with our signature quilted knit cover.
