ABSTRACT:
This disclosure relates to a riser comprising an elongated web having one or more folds which form at least one ridge and slopes extending away from the ridge. When in use as a riser, the web is positioned on edge so that the edge surfaces of the ridges and the slopes engage the bottommost article being supported. The web preferably includes strengthening elements located at at least the ridges. A group of risers are nestable whereby they may be compactly stacked for storage and/or shipping. The edge surfaces have a surface area sufficient to avoid forming a substantial imprint in the article. The risers may be made of a recycled material, such as wood chips, plastic and gypsum, and the risers are reusable.
