The Helix Midnight is a medium-feel mattress designed for side sleepers to help relieve pressure and get quality sleep. Created with input from ergonomic scientists and sleep PhDs, the Helix Midnight uses individually wrapped coils and premium foams to cushion your shoulders and hips, where side sleepers need the most support. On a scale of 1-10 where 10 is the firmest, the Helix Midnight feels like a 6: cozy and soft with cushioned support.
