Abstract
Abstract A corrugated paperboard pallet includes a base member having first and second pairs of opposite sides and a plurality of column-shaped support members secured to the bottom side of the base member. The support members have apertures at opposing ends for receiving flaps from the base member and support blocks, so as to secure the support members to the base member and to provide additional strength to the pallet, respectively. This pallet design can be conveniently shipped and stored until ready for use, and can be entirely assembled by the user.
