A cushioned holder for a cylindrical container for a semiconductor wafer is formed of a stack of layers of a cushioning material that each have a rectangular opening for receiving the container; the layers are spaced from the box by several absorbers having a mirrored pyramidal frustum shape. The shape is easy to manufacture and it provides improved cushioning without increasing the space occupied by the layers.

A stackable cushion formed in layers adapted to be stacked inside a box (14) to enclose a fragile object within a solid rectangular space, one layer (21) being adapted to form a bottom supporting layer and having a substantially unbroken supporting surface, wherein the improvement comprises, a frame layer (16) having a flat upper and lower surface and forming a rectangular opening (15) for enclosing the fragile object, the frame layer having vertical edges (23, 24) parallel to the edges of the box when the cushion is assembled in the box, and absorbers (32) extending from selected positions along the vertical edges of the frame to engage the inside wall (26, 27) of the box, each absorber having a mirrored pyramidal frustum shape with the smaller of the two parallel surfaces of each frustum joined and one of the two larger surfaces adjoining a vertical edge of the frame and the other of the two larger surfaces abutting the inside wall of the box in an assembled cushion.
