How this score is built
Support and spine alignment 25% · pressure relief 20% · temperature 15% · motion transfer 15% · edge support 10% · durability 10% · value 5%. Scores come from the same standardized testing program; instrument-measured categories and hands-on evaluations follow the published methodology, and nothing is scored from a spec sheet alone.

What’s inside the Helix Midnight Luxe
Layer-by-layer construction as published by the manufacturer, listed from the sleep surface down. Foam density describes how much material is in a layer (a durability signal); IFD/ILD describes how soft or firm that foam feels. Density is never used as a feel measurement. Current generation: Current Helix redesign (2025). Specs verified against the manufacturer’s published construction on September 10, 2026.
