Does this mattress isolate motion well for couples?

It rates 8.2 out of 10 for motion isolation, strong for a coil bed, because 875 individually-pocketed coils each move on their own under a deep foam layer that absorbs surface motion. Note that with a 15-inch plush build, larger movements can still be felt more than on a firm bed. Edge support is excellent at 9.1 out of 10, so both partners can use the full width without rolling inward.
