Is it good for couples and light sleepers?

Yes, motion isolation scored 7.7 out of 10. The deep comfort foam absorbs movement on contact, and beneath it each of the 630 coils sits in its own pocket and compresses on its own, so a partner rolling over or slipping out barely disturbs your side. Owners often note they rarely feel a partner move. The pocketed coils are also quiet, with no metal-on-metal contact to squeak over time.
