Our dog is getting up there in age and struggles sometimes to use the stairs, but insists on going upstairs anyway because the bedrooms are up there. I can't imagine us ever installing something like this, but maybe other people would? So long as they could be trained to stay still in it, then it'd make it much safer to go up and down.
