This unit consists of an ample plastic seat which clips onto a sturdy steel frame. It cleans with a simple hose-down and folds up for storage. It can even be left in the cardboard box that it came in, which measures 470L x 370W x only 50mm deep. It is supplied with 6 replacement bags, but almost any bag, such as a kitchen tidy (medium) bag will suffice. The product provides a familiar setting for children who can be temperamental about going to the toilet outdoors. The seat will take a 90kg person.
