An article (1; 100) for collecting urine (300) and stools (400) of a user, the article having a support surface (10A) for supporting the buttocks of the user; and a chamber (20) that communicates with an opening (10E) defined by the support surface (10A) and that presents a bottom portion (22); and a spacer (10) suitable for maintaining the bottom portion at a distance from the support surface. The article has an internal wall element (23; 123) that is situated at a position vertically intermediate between the support surface (10A) and the bottom portion (22) and that is suitable for adopting a first configuration and a second configuration. In the first configuration, the internal wall element forms an obstacle for substantially preventing stools (400) from passing to the bottom while allowing communication for urine (300). In the second configuration, the obstacle is substantially eliminated so as to allow stools to pass to the bottom of the chamber (20).
