Pocket coil systems can be great for back pain sufferers. Unlike open coil systems, pocketed coils can operate independently of one another, contouring to your curves much better than a network of coils all attached to one another. Instead of just compressing in a U-shape that curves under the heaviest parts of your body, pocket coils can compress and rise to fit your unique body shape and sleep position. At the same time, coils also offer more support and resistance than even the most durable foams. This combination of support and flexibility can be a boon for you if you suffer back pain.
