How well does this mattress isolate a partner's movement?

Exceptionally, the best in its group at an 8.9 motion isolation score. Peak transfer sits right at the floor of the 2.78 to 6.08 m/s2 range, a fraction of the typical hybrid, settling in well under a second. The 1000 individually pocketed coils, the highest count in this bed's class, each flex alone instead of transmitting movement across a grid, and the generous 3-inch memory layer absorbs the disturbance the moment it lands. A partner turning over is almost imperceptible.
