My knee, back and balance issues don't allow me to walk very far in one go. Today I'm attending a funeral a mere 300 metres from my front door and I'll be giving my new side-folding rollator walker a try-out . With its wheels flipped up (rears through 90º, fronts through 180º) it's really very compact in the storage mode. Its design encourages users to take a very upright stance when using it too.
