I don't see it as a replacement for stairs, it's too impractical for general use. The only use case seems to be for what their demo video shows, people with limited mobility.


It's also great for? Library, Mezzanine, Archive... stairs take up space, you might even use this for going down mines, wells...what other use cases?


Space requirements are very different to stairs or other lifts.


If you had very limited space and no mobility issues there's a very cheap solution that has existed probably for millennia.


a helicopter?


I think he's talking about a ladder.


Rope with hook. You can even use that when visiting friends.


Maybe staying downstairs?


I think he means you could pay someone to go upstairs for you


is this marketed to the same people that need an electric chair because otherwise they can't get up?
