As the story goes...

Goldilocks goes into the bear's house and sits on papa bear's Counter Assault Bear Keg stool and says, "This stool is too tall." Then Goldielocks sits on the baby bear's Bear Vault BV450 stool and says, "This stool is too short." And finally, Goldilocks sits on the mama bear's Bear Vault BV500 stool and says, "This stool is juuust riiight!"

Meanwhile ...

The NPS does not allow bears to sit on ursacks in a number of areas because of past reports that sitting on ursacks has rewarded bears with hemorrhoids. The insertion of an aluminum liner to stiffen the ursack has been suggested as a redesign to prevent hemorrhoid rewards while still providing a lighter more portable stool than the rigid alternatives.
