The Helix Twilight is a firm all-foam-and-coil hybrid mattress rated about 8 out of 10 on firmness, built for side sleepers who want strong pushback under the shoulders and hips. Individually wrapped coils sit under premium foams, so it feels lively rather than dead, with more support than a medium mattress. It suits heavier side sleepers and back sleepers who sink too far into softer beds. Rivals in the same hybrid class often land at medium or medium-firm; the Twilight is one of the firmer options, which lighter side sleepers may find too hard.
