The device presented here within is an ergonomic toilet arrangement facilitating a toilet user assuming an optimal defecation posture. The toilet bowl or seat is displaceably mounted on a support structure so that when the user mounts the apparatus it is displaced such that the front of the seating arrangement is upwardly inclined relative to the horizontal. Such a position disposes the user's thighs and trunk at an angle significantly less then ninety degrees during defecation thereby diminishing bowel function complications.
