Pocket spring mattresses, also known as individually encased coil mattresses, are a type of innerspring mattress designed to offer unparalleled support and comfort. Unlike traditional innerspring mattresses, where the coils are interconnected, pocket spring mattresses consist of hundreds or even thousands of individual coils, each encased in its fabric pocket. This design allows each spring to respond independently to the sleeper’s movements, contouring to the body’s shape and providing tailored support.
