Hospital chairs and everyday chairs are both technically wheelchairs, but they are totally different products for different purposes.
I don't think these wheel chairs have any magical properties over the stuff used in Germany. Other than that they are really expensive.

If you need a wheelchair for a couple weeks it's fine. If you need it for life, not so fine. People who can't afford a proper day chair or are mired in insurance hell sometimes make do with them, but they can suck ass. They're totally different products and are suitable for different uses.
They're different chairs; $200 hospital chairs on Amazon have no relationship to the price of the sort of chair the company from the article is working on.
