Two of the legs come up a kind of a v shape. So, as a cane, it only has one leg. But, the other two are pretty close to the main one, so I have never had a problem with that. I would like one that folded up completely, but, usually, if I need the seat, I can use the cane as well. And, my balance isn't great, so using one with only one leg would have me really tipsy....without the alcohol!
Bought one for an elderly friend who still loves to travel...a lot...and she swears by it.
