We use Marshal coils, also called "pocketed coils" in some of our mattresses Each coil is wrapped in a fabric encasement, and is usually tempered twice, once with heat and once with electricity. The brand Simmons uses pocketed coils in its Beautyrest mattresses. Additionally, when two people sleep on the same mattress, the individually wrapped (or individually pocketed) coils provide motion separation (when one person tosses and turns, the other doesn't feel it.) This is important because when one person tosses and turns, it may not completely wake the other person, but, it can take them out of a deep sleep which is when the body does all of its regeneration. When a sleeper is undisturbed at night they can fall into that deep sleep faster, stay in a deeper sleep longer, and wake up feeling more refreshed because it allows the sleeper to get more use out of their sleep.
