Is it good for couples with a restless partner?

Yes. The 800 individually pocketed coils each move on their own, and the soft memory layer up top absorbs motion right where it lands, scoring 7.9 out of 10 for motion isolation. We measured peak transfer in the 3.0 to 6.3 m/s2 range, settling in about a second, well below a typical mattress. On a plush bed the thick foam actually helps, soaking up jostle on contact, so a partner shifting at night is unlikely to wake you.
