How good is motion isolation for couples on this Sealy hybrid?

Strong, at 8.8/10. Each of the 1100 coils is wrapped in its own fabric pocket, so one compressing barely disturbs its neighbours, and 2 inches of memory foam absorb movement the moment it lands. If your partner gets up early or shifts often, their motion stays largely on their side. The firm support also keeps the surface stable, making this a dependable choice for light-sleeping couples.
