The Wunda Chair was also known as “the Home Reformer” because it took up much less space in one’s tiny New York City apartment. It has a smaller mat platform on top with a pedal below with spring resistance. Its size requires more precise movement and balance, making it a challenge for the intermediate client. For beginners, a backboard and handles are added for support. Add a pillow and turn it on its side, it could be disguised as a living room chair.
