Need a hand?

So we went the other day to ge chairs for my grandparents, ones that help you standup, we went to a shop that sold all sorts of mobility aids ad other things that help you when you are less than spritely any more. We spotted this?Which made me giggle, because well I'm imature like that, but then when we noticed the label on it we all but fell over laughing:
thats right a "bottom buddy" I wonder why they replaced that...?
