How is it for couples and motion transfer?

Excellent for sharing a bed, with an 8.2 motion-isolation score. All-foam construction is the gold standard here because there are no springs to carry movement sideways, and the dense TEMPUR comfort foam absorbs a partner rolling over or climbing in before it reaches you. Peak roll-across acceleration measures very low, in the 0.8 to 4.1 range, and movement dies out in under a second. A restless partner barely registers on your side.
