The bowl further includes a lower base and a hollow interior. The oval upper opening slopes gradually upwardly from the rearward extent to forward extent. The upper opening also has a peripheral thickness which increases from the rearward extent to the forward extent. The forward extent of upper opening functions to support the knees and the underside of the upper legs of the user. The footrest has a top surface, an upwardly inclined forward portion, and a rearward portion. The rearward portion includes a recessed edge. The recessed edge is specifically adapted to be removably secured to the lower base of the bowl.
