ABSTRACT:
An inflatable structure, includes a base and a barrier attached to the base which is capable of being inflated to a predetermined shape in order to define a chamber. A door in the barrier allows access to the chamber. The base includes a source of gas for inflating the barrier and for circulating within the chamber. The barrier is constructed as a twin-walled structure having inner and outer walls defining an air flow space therebetween. Holes are provided through at least portions of the inner wall to provide a means for circulation of air from the space into the chamber. When not in use, the aerator may be deflated and folded for compact storage and shipment.
