The Helix Midnight Core with GlacioTex™ Cooling Cover and ErgoAlign Layer combines everything that has made the Midnight Helix's most popular mattress with two of Helix's most popular upgrades. The result is a hybrid mattress that delivers balanced pressure relief, targeted lumbar support, and an upgraded cooling sleep surface for exceptional comfort throughout the night.

Comfort & Construction

The Helix Midnight Core begins with the GlacioTex™ Cooling Cover, designed to create a cool-to-the-touch sleep surface while helping dissipate heat for a more comfortable sleeping environment. Beneath the cover, HD Gel Memory Foam and HD Memory Foam work together to provide contouring comfort and pressure relief around the shoulders and hips while maintaining the balanced support side sleepers appreciate.

The addition of the ErgoAlign Layer reinforces the center third of the mattress to provide enhanced lumbar support beneath the hips and lower back. Working together with the Edge Support Wrapped Coil System, it helps promote healthy spinal alignment while delivering targeted support, reduced motion transfer, and reinforced edge stability. A durable HD Base Foam foundation completes the construction, creating a stable hybrid mattress designed for lasting comfort, dependable support, and long-term performance.
