The Helix Dawn is a firm mattress designed for back & stomach sleepers to help relieve pressure points and get quality sleep. Created with input from ergonomic scientists and sleep PhDs, the Helix Dawn uses individually wrapped coils and premium foams to align your spine and hips, where back & stomach sleepers need the most support. On a scale of 1-10 where 10 is the firmest, the Helix Dawn feels like an 8: it feels like you’re lying on top of it, without sinking in.
