Our Verdict
Helix Midnight 2024
Helix Midnight Luxe 2025
The Helix Midnight Luxe 2025 is an updated version of the Helix Midnight 2024. It has a different feel and a slightly better performance overall. The 2025 version has a medium firmness level, so it's a little firmer than the medium-plush 2024 version. It offers better cooling as well as marginally better edge support and motion dissipation. However, it uses less resilient memory foam in its comfort layer and also includes a layer of memory foam in its quilted layer, which results in a less responsive mattress.
