Each spring operates independently, responding to the unique contours and movements of the sleeper's body. This design allows for better motion isolation compared to traditional innerspring mattresses, where all the springs are interconnected. Because each spring moves independently, pocketed spring mattresses provide targeted support to different parts of the body. This can help alleviate pressure points and promote proper spinal alignment, resulting in a more comfortable sleep experience.
