Jethro_uk submitted this idea :
Stairlifts - unless you are paying $$$$$ require that a person in a
wheelchair transfer to use them (and there's a corresponding free
wheelchair at the other end of the destination).

They are mostly helpful for those with some mobility, but who might
struggle with stairs.

Rather than sourcing from a 'refurb' company, take look on ebay from
private sellers. There are always plenty on there, people find they no
longer need them or move into a house with one fitted and remove it -
they fetch very little money, compared to original cost.
