Wheelchair Mobility

Wheelchair Mobility
In the game of Scategories, an opponent listed a wheelchair as furniture. Is this a valid piece of furniture?

Nowhere does the Americans with Disabilities Act (that I can find) list a wheelchair as being a piece of furniture (like a desk or table) but rather, only as a mobility device. Furthermore, no furniture stores carry wheelchairs.

is a crutch a piece of furniture?
