It is usually used by old people with limited mobility. After I healed, I gave it to my mother in law for her knee replacements.

Looks like a chair/walker type deal. Use the handles to get up, then turn round and use it for support when they waddle along. I think they have brakes like a bike in case it starts moving faster than continental drift.
