Lab Verdict
Helix ran measurably cooler in our 60-minute body-heat test (2.4°F surface rise vs. 3.8°F on the DreamCloud). Couples should note that the Helix dampened motion more aggressively (0.09g peak vs. 0.21g). Side sleepers will feel less shoulder pressure on the Helix (peak 26 mmHg vs. 31 mmHg). Perimeter compression was nearly identical — neither bed is the obvious pick on edge support alone. DreamCloud returned more energy on rebound (38% vs. 28%), favoring combo sleepers.
