Pocketed coils are individual springs encased in fabric pockets, allowing them to move independently. This design helps to provide targeted support and reduces motion transfer, making them popular in mattresses and upholstered furniture. The pocketed coil system adapts to the body's shape, offering better spinal alignment and comfort. Unlike traditional innerspring mattresses, where coils are interconnected, pocketed coils enhance durability and responsiveness, catering to various sleep positions and preferences.
