If you don't want to move, then get a stairlift. I did, for the basement stairs and was so glad. I Didn't need it all the time, then, but before long I did and even after I started using a Scooter around the house, I could still transfer to it and use it, with a WC at bottom of stairs.

I also got a ramp put in, from house down to garage. That was a definate must have, in order to remain independent and get out of the house on my own. Oh and a van lift for my scooter too.

I had to pay out of pocket for all theses things. My Insurance paid for my, more expensive, Scooter and that's it.

Good luck and enjoy..
