Referring to FIG. 5, the seat member 15 is a unitary structure that in one embodiment has a solid or rigid base member 41 with foam padding 35 or any other type of material that provides a measure of resiliency and comfort. The cushion 35, in one embodiment, is approximately 2′′ in thickness and covered with a seat cover 37 made of nylon or water repellant fabric in order to prevent undue staining. The base member 41 is a platform in the form of a flat, rigid board to which the cushion 35 is secured. The platform 41 rests upon a front platform support or panel 43, a mid-section platform support 51 and a lower platform base 47. The front and mid-section platform supports, 43 and 51, are hingedly connected at opposite ends to the upper and lower platforms 41 and 47. The hinged connections 65 are shown in FIG. 6. The platform supports 43 and 51 in this embodiment are panel sections spanning the width of the seat member as shown in FIGS. 5 and 6. These are shown by way of example and not limitation; the supports 43 and 51 may also be defined by rods or posts at spaced intervals under the seat cushion for supportive elevation of the seat. Further, the platform supports 43 and 51 are not limited to panel sections of a certain width. The platform 41 is parallel with the lower platform base 47 and perpendicular or angled with respect to the midsection platform support 51 and the front support member 43 when the seat member 15 is in the first horizontal position. The front platform support 43 and the mid-section platform support 51 are aligned parallel to the seat platform 41 and the platform base 47 when the seat member is in the storage or vertical position. This is shown in FIGS. 8 and 9. The cushioned seat member 15 has a built in support structure, as described above, providing for elevation and support of the base member 41 and the cushion 35.
The outer shell 12 which is shown in FIG. 6 includes the upright back support 13, the sidewalls 17, 17′, the foldable front wall 19 and the bottom panel 32. The outer shell 12 is a unitary structure that provides upright and lateral support for an infant as well as support for the seat member.
