Abstract
An air mattress includes a first air cell, a second air cell, a plurality of third air cells, and a body-lifting air cell. The second air cell includes a first air chamber, a second air chamber, and a structurally-weakened region. The body-lifting air cell is below the second air cell and at least one of the third air cells. The body-lifting air cell is inflated by an air source controlled by a control system. When the body-lifting air cell is inflated, a vertical distance between the top of second air cell and the bottom of air mattress is greater than a vertical distance between the top of first air cell and the bottom of air mattress. When the body-lifting air cell is inflated, the second air cell has a lower structural strength than the other air cells to have a cushioning effect against external forces.
