One of my favorite movies growing up, the Gremlins! We even named our dog after one of the characters, the sweet little pre-gremlin, Gizmo! He was such a cute puppy, one of those popped eyed little pups. Do you remember the part in the movie when the elderly lady rides up the stairs in the chairlift, I was so amazed as a child! I secretly wanted one in our house, what fun to have your own lift! (if only we had a two-story house) haha.
Do stair chairlifts really exist? You bet! there is a company called Value Stairlifts stair lift that sells these amazing devices. I know in the movie as a child it was more of a wonderment, but now as an adult I could see where one might really be useful, more than useful a necessity if you have a home that you love and wish to remain in. It would allow someone who is disabled in one way or another to still live in their multi-level home and enjoy every part of it. DId you know you can even buy a stairlift for an outdoor stairs, or curved stairs, and they even sell reconditioned stairs that might help with a fixed budget.
