My grandmother lives in a nursing home where she uses one of the many knee walkers used that the nursing home provides. She is really lucky to live in a place like this that takes care of her this way. Not all seniors are as lucky as my grandmother, though. Most seniors need to get their knee walkers on their own, or ask somebody from their family to do it for them. Every elderly should have an easy access to something as useful as a knee walker in my opinion.
