Yeah, that is something else you might want to take into consideration is that small footprint speakers are easily tipped over, which is why, I'm assuming, that they don't want bookshelf speakers on stands. Maybe you could put a pair of bookshelf speakers on a shelf? Or dresser? Otherwise, the first that came to mind for me were totems.
Good luck! And visit your Grandma often ;-)
