Abstract
A method of stuffing an aerated expanded flexible filler into a snug fitting cover, wherein air is evacuated from the filler while resting upon a support so as to shrink the filler and permit rapid application of the cover thereto. The apparatus includes a cantilevered chambered support with multiple openings in its filler supporting surface and selectively operable means for withdrawing air from the chamber.
