Body support having an air core (2, 3; 52) and a bellows (6, 7; 56), integrated into a side edge portion (4, 5) from a compliant filling material, and having compliant filling material in an inner space. The body support further comprises passages (13, 14, 15; 63, 64, 65) which connect the bellows (6, 7; 56) with the air core (2, 3; 52) and connect the bellows (6, 7; 56) and the air core (2, 3; 52) with the surroundings, and comprising valves (16, 17; 67, 70) for blocking in a condition of rest air flow from the air core (2, 3; 52). Because the inner space of the bellows (6, 7; 56) in the condition of rest is in open communication with the surroundings, the compressibility of the bellows filled with filling material is well adapted to the compressibility of adjacent side edge portions, which are also filled with filling material, and the maximum load of the bellows is limited.

[ What I claim is:] [1.] A conforming body support having an outer contour and comprising disposed within said outer contour, an air core, a side edge portion disposed contiguous to the air core and formed from a compliant filling material, and an inflating bellows disposed in a fixed position within said side edge portion and operable to inflate said air core while in said fixed position, said body support having a condition of rest and said inflating bellows being airtightly separated from the air core in said condition of rest, said inflating bellows comprising an inner space and a compliant filling material in said inner space tending to expand said inflating bellows to an expanded state;said body support further comprising:a system of passages connecting said bellows with said air core and connecting said bellows and said air core with a surrounding spatial area surrounding the body support, anda valve system for selectively blocking air flow from the air core when said bellows is said condition of rest, the inner space of the bellows being in open communication with the surrounding spatial area via said system of passages when said body support is in said condition of rest.
