Abstract: A portable enclosure has a base on which a seat, a back rest, and canopy are supported. The front, bottom, sides and back of the enclosure are closed by curtains, with the front curtains being held upright on poles which project upwardly from stabilizing arms which in turn are fitted into the base. The space enclosed by the curtains is warmed with heater. The enclosure may be reduced to a highly compact condition by removing the seat and placing the forward stabilizing arms in hollow seat posts on which the seat normally rests. The canopy also lowers and is to a limited extent disassembled and stored on the base. The heater likewise fits on the base. The back rest is turned around and forms a back pack for easily transporting the enclosure.
