Claim:
1. An air mattress with an internal pump, comprising: a plurality of air cell groups lined up in a lengthwise direction of the air mattress, each of which groups is made from a plurality of bladder-shaped cells, all of the bladder-shaped cells of said air cell groups being rod-shaped cells extending in a widthwise direction of the air mattress, and being lined up in the lengthwise direction of the air mattress; an air supply/release pump internally disposed in the air mattress; an air tube linking said air cell groups and said air supply/release pump in a system for each air cell group of two or more air cell groups out of said air cell groups; a connector for connecting said air supply/release pump and said air tube detachably; and a controller for controlling the pressure within the bladder-shaped cells for each of the air cell groups among the air cell groups, wherein the bladder-shaped cells of the air cell groups other than the air cell groups corresponding to a heel area of a person lying on the air mattress extend to an edge of said air mattress; the length of the bladder-shaped cells of the air cell groups corresponding to said heel area is up to 30% less than that of the other bladder-shaped cells, and a space is left between the cells and the edge of said air mattress; and said air supply/release pump is disposed in said space, wherein when the connector is removed from the air supply/release pump, connections between the air tube and the air supply/release pump in the system are released such that the air within the bladder-shaped cells is released.
