Is this plush hybrid a good choice for couples?

Yes. It scores 9.2 out of 10 for motion isolation, putting it in the top tier for shared sleep. A partner's movement peaks low and damps out within about a second instead of rolling across the bed. Three layers cooperate: the 1850 pocketed coils each move independently, 2 inches of memory foam swallow movement where it lands, and the micro-coil tier adds finer isolation. One person turning over rarely disturbs the other.
