How well does this memory foam mattress isolate motion for couples?

Excellently, this is its standout for couples. Peak transfer measures as low as 1.34 on the meter scale, far quieter than a spring bed's ripple, with movement settling in about half a second. The memory-and-poly stack over a dense foam core absorbs a partner's roll or a midnight trip before the energy can cross the bed, and with no springs there is no transmission path. A restless partner simply will not reach your side.
