Abstract: This invention relates generally to a portable, self-supporting baby carrier apparatus. More specifically, the invention concerns an apparatus that is easily set up or collapsed and stored, and when it is set up, it becomes a free-standing, self-supporting baby jumper or the like with a solid support structure. The invention overcomes the drawbacks of the earlier swing sets and jumpers by providing a stable frame mounted on a base. Further, in the case of the baby jumper, the jumper set is suspended from a specific spring configuration that restricts the lateral movement of a child in the jumper seat.
