Abstract: A load-bearing pallet assembly comprises a resilient polymeric core including top and bottom halves which have means for interconnecting and easily disconnecting the halves but only when desired. The top half includes a top support panel having top corners, a flange portion which extends about the periphery of the top support panel and projects downwardly therefrom and a set of four tabs projecting downwardly from the top support panel at each of the top corners. The bottom half includes a base having bottom corners, a shoulder portion which extends about the periphery of the base and projects upwardly therefrom, and a boss shaped like a truncated pyramid which projects upwardly from the base at each of the bottom corners. Each of the bosses has a square slot for receiving four tabs of the top half to interconnect the top and bottom halves. The bottom half also includes head portions which project upwardly from the shoulder portion at each of the bottom corners and at midpoints therebetween.
