Does this Euro Top mattress isolate motion well for couples?

Yes, it scores 8.5 for motion isolation, strong for a coil bed. Each of the 1000 coils is fabric-wrapped and moves on its own, so a partner's motion stays on their side instead of rolling across, and the memory layer on top absorbs what is left. Peak transfer measures as low as 2.74 on the meter scale. A restless partner or a climbing kid is far less likely to wake you.
