You can't see the base here, but there is no tray under my 72 qt cooler. Heavy-duty bungees attach to the legs of the leaning post and surround the cooler. In fact, the 72 qt Igloo has grooves molded into the cooler sides just for this purpose.
Keeps the floor under the leaning post perfectly flat, there is nothing to trip over, and nothing to catch water or gunk.
