Another piece of mind if she’s alone in a two story house, or has laundry room in the basement, is the Acorn chair lifts.
We had two installed for my dad, and after he passed my mom said she’d keep them. Some days she uses them, other days, don’t laugh, she uses them to send laundry baskets or items that are to big for her to carry up and down the stairs, that way she can walk up or down and hold onto the railing and not try to juggle things in her arms. She’s going to be 74 in June.

She does have a basement, but we've told her we don't want her trying to go down there. I think the basement stairway is too narrow for one of those lifts though. She does have a good local handy man who does home repairs that can go down there and the laundry is on the main floor. Before she kicked us all out, we moved anything in the basement she might need to the main level so she doesn't have to go down there.
