Calling it a wheelchair is a mistake, I’m guessing made by the journalist. The inventor said that he wanted to position it somewhere between a walker and a wheelchair. It’s a mobility assistance device, like a cane, walker or wheelchair, but something new. It looks like a far more supportive and adaptable rollator (Walker with seat). One that can keep people upright and almost walking longer than a standard walker or rollator can, depending on their condition and abilities.
