The Pollywog transforms from a wheelchair to a transport chair in a snap! If you need both a wheelchair and a transport chair, then the Pollywog is for you. Why store bulky wheelchairs around your house? With the patented quick-release button, the large 24" wheels come off and the Pollywog becomes a transport chair on four 8" wheels. Then with another easy click, the large wheels go back on, and it's a wheelchair.
