Is this mattress a good choice for couples?

Yes, especially for the lighter side sleeper it targets. Motion isolation scores 7.8 out of 10, with transferred motion measured at 3.86 and settling within about a second. Each of the 800 coils sits in its own fabric pocket, sending a partner's movement straight down rather than across the bed, and the soft top muffles the initial jolt. The strong edge also lets both partners use the full surface without rolling toward the middle.
