Abstract: A device for supporting a person's extremities includes a first arm, a second arm pivotably coupled to the first arm, and an appendage support coupled to the first and second arms. The device is configurable in a use position, in which the appendage support is not parallel to at least one of the first and second arms while remaining coupled to the first and second arms. The device is also configurable in a collapsed position, in which the first and second arms and the appendage support are generally parallel to one another while remaining coupled to one another.
