How well does this firm hybrid isolate motion for couples?

Impressively well for a firm bed, scoring 8.4/10, the best in the Centennial Hybrid family. The 1000 individually pocketed coils each flex on their own, so a shift on one side is not transmitted sideways through a connected wire grid the way a classic innerspring would be, and the memory-foam layer catches the initial jolt at contact. Firm beds sometimes pass motion more readily than soft ones, but this stays firmly in very-good territory, reassuring for couples.
