A cushion apparatus that may be advantageously utilized as an end cap for packaging shock sensitive products is disclosed herein. In one embodiment, the cushion apparatus includes a base member having one or more side walls having inner product bearing surfaces defining a product receiving cavity. The product receiving cavity has an open bottom end through which the product is received and an opposing top end. An axial deflection member is disposed over the top end of the receiving cavity. The axial deflection member is an arc-shaped elastic material member arching over the top end of the product receiving cavity. In one embodiment, the cushion apparatus further includes multiple radial deflection members extending radially from the base member to define a multi-sided bearing support perimeter having multiple corners.
