I'll probably have a slightly different list. I am an amputee without a prosthesis and reside in a two-story house (long story). The ability to use a wheelchair both upstairs and downstairs is my favorite feature. Since it doesn't go anyplace, I have a nice one below and an addict one above, which I can also use for transportation with

I also have a few pieces of wood that are the same size as my kitchen drawers, so I can pull one open, set the wood inside, and use it to eat, prepare meals, or use my computer. My chair easily fits beneath it because it has been pulled out.
