Why You'll Love It

The Twilight Core with GlacioTex™ Cooling Cover and ErgoAlign Layer combines firm hybrid support, advanced cooling, and targeted lumbar reinforcement into one thoughtfully engineered mattress. It delivers the same supportive feel as the original Twilight while adding two of Helix's most popular upgrades.

Comfort & Construction

The Helix Twilight Core begins with the GlacioTex™ Cooling Cover, engineered to create a cool-to-the-touch sleep surface while helping move heat away from the body. Beneath the cover, HD Gel Memory Foam and HD Memory Foam provide contouring pressure relief while preserving the Twilight's firm, supportive feel.

The addition of the ErgoAlign Layer reinforces the center third of the mattress to provide enhanced support beneath the hips and lower back. Combined with the Edge Support Wrapped Coil System, it promotes healthy spinal alignment while delivering targeted support, reduced motion transfer, and reinforced edge stability. A durable HD Base Foam foundation completes the construction, creating the most feature-rich version of the Helix Twilight Core.
