The Helix Midnight Core Breathe Knit is the brand's bestselling medium-feel hybrid mattress, engineered for side sleepers and anyone who tosses and turns. A breathable knit cover tops layers of Memory Plus Foam and high-grade responsive foam, cradling the hips and shoulders without letting you sink too far. Underneath, individually wrapped pocketed coils with reinforced edges deliver supportive lift and excellent motion isolation — so couples sleep undisturbed.

Backed by a 120-night sleep trial and a 10-Year Limited Warranty, the Midnight is handmade in Helix's Arizona facility from CertiPUR-US certified and GREENGUARD Gold certified materials. Fiberglass-free.
