Lab Verdict
Cooling was a wash — both mattresses landed within half a degree of each other after 60 minutes of body heat. Couples should note that the Beautyrest Black dampened motion more aggressively (0.1g peak vs. 0.18g). Pressure mapping put both beds well under the 32 mmHg capillary-closure threshold for side sleepers. Perimeter compression was nearly identical — neither bed is the obvious pick on edge support alone. Combo sleepers will get more rebound from the Beautyrest Black (57% bounce vs. 42%).
