The present invention relates to a collapsible/foldable structure that mayinclude a top roof and a bottom platform. A pair of sidewalls may be provided eachof which may be pivotally attached to the roof. The sidewalls may include at leasttwo side section such as an upper and middle section. The sidewalls may also includea lower side section. The upper and middle sections may be pivotally attachedto one another and the middle and lower side section may be pivotally attachedto one another so that the upper and middle sidewall sections can be pivoted inwardlytowards the bottom platform to provide a collapsed condition. The sidewallsmay also each contain an outer and an inner surface thereof wherein the outer surfaceof the upper side wall and the outer surface of the adjacent middle side wall forman angle that is greater than 180 degrees when the structure is in an expanded orcollapsed condition. In addition, the inner surface of the middle wall sectionmay overlie the inner surface of the upper wall section in a collapsed condition.
