Abstract
An air mattress with an internal pump has a plurality of air cell groups lined up in the lengthwise direction of the air mattress. Each of air cell groups has a plurality of bladder-shaped cells lined up in the lengthwise direction of the air mattress. The air mattress has an air supply/release pump; and an air tube linking the air cell groups and the air supply/release pump in an independent system for each air cell group out of two or more air cell groups. All of the bladder-shaped cells are rod shapes extending in the widthwise direction of the air mattress, and the length of the air cell groups corresponding to the leg area of a reclining person is up to 30% less than that of the other bladder-shaped cells, leaving a space between there and the edge of the air mattress in which the air supply/release pump is disposed.
