Construction
This model's name doesn't encode its materials, and we haven't tested it in our lab.
For construction detail, start with the Helix brand hub or our mattress types guide, which explains how foam, latex, hybrid, and innerspring builds differ in feel and durability.
Helix signature technology
- Sleep Quiz Matching: 20-question diagnostic that maps you to one of 14 hybrid configurations — the most granular model selection in DTC mattress.
- Memory Plus Foam: Helix's higher-density memory foam used in Luxe-tier models for deeper pressure relief without losing responsiveness.
- Glacio High-Grade Cooling Cover: Phase-change cover on Elite models — our thermal lab measured a 2.7°F surface-temp reduction vs. standard cover.
