Lab Verdict
Purple held heat-neutral better than the Puffy (2.5°F surface rise vs. 3.2°F). Motion isolation was roughly equivalent; either is safe for a partnered sleeper. 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. Purple returned more energy on rebound (58% vs. 39%), favoring combo sleepers.
