Does this springy hybrid isolate motion well for couples?

Reasonably well, scoring 8.2 out of 10, with measured peak motion around 5.63 m/s2 settling in about a second. Because each coil is pocketed and compresses on its own, a shift on one side does not travel straight across. The honest caveat: with only a half-inch of comfort foam and no memory foam to absorb surface energy, this lively firm bed passes along a little more than a plush foam build, so a very light sleeper may notice movement.
