ABSTRACT:
A collapsible play structure has one or more play modules connected together, each play module comprising at least three foldable frame members, each having a folded and an unfolded orientation. A fabric material substantially covers each frame member to form a side panel for each frame member when the frame member is in the unfolded orientation. Each side panel further comprises at least three sides. The left side of each side panel is connected and hinged to the right side of an adjacent side panel, and the right side of each side panel is connected and hinged to the left side of another adjacent side panel. The bottom side of each side panel is adapted to rest on a supporting surface to support the play module.
