Support structures which can be placed around the waist of a user, for example a mother nursing twins. A front member and a rear member cooperate to provide an openable enclosure which can first be placed around, and then closed around, the waist of the user. The front member provides a platform which is in front of the user and on which are placed one or more babies, or other items desired by the user. The platform has desired characteristics, for example a first surface which is horizontal and a second surface which is inclined towards the user.
