A polymorphic body support system wherein the surface which engages the body is provided by a plurality of support elements to effect a contour support to the person thereon. Each support element is a closed flexible bag partially filled with a plurality of beads characterized as non-absorbent, non-compressible and capable of free flow with respect to each other within said bag when subjected to the weight of a body member. Varying degrees of bag filling produce varying support characteristics.
