5-zone mattresses have different zones to relieve the head, neck, shoulders, hips and pelvis while sleeping. This type of mattress can be turned and rotated, as the neck and shoulder zones also act as support for legs and calves. Due to the zone structure, the lying surface is used in a balanced way, which ultimately leads to a longer service life. 7-zone mattresses, which have more detailed classifications, also work in this way. The difference is that they stabilize or relieve several body regions with the help of additional bearing zones, such as the lumbar spine. In addition, these mattresses adapt up to 90 percent to the bodies of adults, which is why they can be used flexibly and serve a wide range of sleep types.
