Abstract
Abstract A toilet aid comprises a rear fixing bracket for mounting on a WC pan using the normal seat-attachment bolt holes of the latter. Two identical side support structures of inverted U-shape each provides a side user support arm, a front support leg and a rear support leg. The rear support legs extend through pivot bores in the bracket which provides lateral support for the legs with the side support structures independently pivotable about respective pivot axes.
