Frequently Asked Questions
What's the difference between the Helix Luxe and Helix Elite mattresses?
The Helix Elite is the ultimate upgrade from the already premium Luxe model. The key differences are:
A Dual-Coil System: The Elite adds the NanoCoil® pressure-relieving layer for enhanced cushioning and durability.
More & Better Comfort Layers: The Elite has more specialized foam layers, like the ultra-high density SupremeSupport Memory Foam.
A Thicker Pillow Top: A plush 2-inch quilted pillow top for a more substantial, luxurious feel.
GlacioTex™ Elite: The most advanced and effective version of their cooling cover technology.
Is the Midnight Elite good for side sleepers?
Yes. With NanoCoils®, gel foams, and zoned lumbar coils, it relieves pressure at hips and shoulders while keeping the spine aligned, ideal for side sleepers.
How does the cooling system work?
The GlacioTex™ Elite fabric draws heat away instantly, while CoolForce™ graphite ribbons pull 22% more heat from the body for over 12 hours of continuous cooling.
