1. A body support device having a primary axis parallel to the direction of a centerline of a human body which the support device is adapted to support comprising:
- at least one flexible container adapted to be filled with a fluid medium, said at least one flexible container lying coextensive with at least a portion of the device and arranged parallel to the primary axis;
a flexible mattress having longitudinal edges, said mattress positioned above said flexible container; and
a plurality of load transmitting elements having lower surfaces of varying shapes, said plurality of load transmitting elements arranged between said mattress and said flexible container, said flexible container being in contact with at least two adjacent load transmitting elements, the shapes of the lower surfaces varying from each other in accordance with the volume to weight ratios of the several parts of the human body which the device is adapted to support.

Abstract
A body support comprising one or more flexible containers and a plurality of load transmitting elements which have contact surfaces the area of which at a number of elements differs from the area of other elements to obtain an adaptation to the differing ratio of volume to weight of the parts of the human body, and a container which can be used in the body support which container has two outer layers of nonpermeable material and two inner layers all layers, being interconnected by cross seams to form chambers interconnected at the edges.
