ABSTRACT:
A method for making a support for an object wherein a hollow conduit member having closed ends has cut therein an opening to receive resilient foam reacting materials therethrough. In the cutting of the hollow member, a flap remains at the opening so that upon reacting of the foam mix, the foam rises or increases in volume forcing the flap into its original position thereby closing the opening. In a preferred embodiment the hollow conduit member includes at preselected positions therein hollow inserts arranged with axes at right angles to the axes of the hollow conduit member, the inserts being surrounded by the resilient foam materials.
