The literal construction difference
- Helix Dusk Elite
- Responsive Foam layers tuned to a Medium feel for back and stomach sleepers
- Helix Midnight Elite
- Responsive Foam layers tuned to a Medium feel for side sleepers and people who toss and turn
Why it matters: Helix keeps the cooling, pressure-distribution, lumbar, microcoil, and edge systems equal, then changes how the responsive foams yield and push back. Dusk: Its responsive layers support the hips and limit excess lower-back sink for sleepers facing up or down. Midnight: Its responsive layers spread pressure across the shoulder and hip without the deepest Soft cradle. The better model is the one that supports your usual position, not the one with the firmer name.
