I found one on Amazon that I thought would be a narrower size overall, and the legs having a bend at wheels instead of straight- so they are less trip factor & less running over toes of helpers..
But after it arrived only the handle section was narrow, the wheel base was as wide as what we had already, but luckily Amazon allows free returns, most of the time.
I did include a note on the return reason that the measurements on the description were misleading..it was not smaller than what we had..

I happened to stop in at a resale store and they had a perfect sized one in very nice condition ..so I grabbed it for dad.. I'll try to get the brand / style /numbers off it next time I go..
