Lab Verdict
Purple held heat-neutral better than the Nolah (2.5°F surface rise vs. 3°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. Responsiveness was comparable; repositioning effort should feel similar on either.
