Comfort & Construction

The Helix Dusk Core begins with the GlacioTex™ Cooling Cover, engineered to create a cool-to-the-touch sleep surface while helping draw excess heat away from the body. Beneath the cover, HD Gel Memory Foam provides gentle contouring to help relieve pressure, while HD Adaptive Foam creates responsive comfort that adapts naturally throughout the night.

The addition of the ErgoAlign Layer reinforces the center third of the mattress, providing enhanced support beneath the hips and lower back to encourage healthy spinal alignment. Below, the Edge Support Wrapped Coil System responds independently to movement, helping reduce motion transfer while reinforcing the perimeter for improved edge stability. A durable HD Responsive Foam base provides the stable foundation that completes the mattress's balanced hybrid design.
