How quiet is it and how is motion isolation for couples?

Very good for couples, scoring 8.7 out of 10 on motion isolation. The 1,100 coils are individually pocketed so each moves on its own, and several inches of memory foam plus latex above them absorb movement on contact. It is also quiet, with no metal-on-metal squeak, so a restless partner is unlikely to wake you when shifting or getting up.
