What are Pocketed Springs?

What Is a Pocketed Spring?

Also known as wrapped coils, encased coils, encased springs, or Marshall coils, pocketed springs are designed to provide proper support with exceptional suppression of motion transfer between sleeping partners. While traditional coil systems have springs that are wired together, springs in a pocketed spring system are individually wrapped in a fabric encasement to create separate springs. This design allows each pocketed spring to move independently, respond quickly to movement, and conform to the contours of your body.

The Art of Staying Asleep

Just because you change positions during the night doesn't mean that your partner has to. Most sleepers are likely to move anywhere from 3 to 36 times in a single night. If you share a bed, that's over 100 adjustments. The coils in a traditional innerspring mattress are attached to one continuous wire, which means you'll feel each and every one of those disturbances.That's why mattresses with encased spring systems are precisely designed to reduce motion transfer. Because the springs aren't connected, each works independently, meaning weight applied to any one spring will not affect the surrounding springs. That's the secret to enjoying restful, undisturbed sleep.

Why Is Undisturbed Sleep So Important?

While exercise is essential for stimulating circulation and the elimination of toxins, quality sleep gives your body an opportunity to cleanse, repair, restore, and rejuvenate on a deep, cellular level. Could there be an easier way to nourish your body and mind? With the right mattress, you can do it in your sleep.
