Playsets with pop-up structures
Abstract:
Playsets are disclosed. The playsets may include a support surface and a pop-up structure. The pop-up structure may be adapted to be selectively transitioned between a stowed configuration and a deployed configuration. In the stowed configuration the pop-up structure may be collapsed and may extend along the support surface. In the deployed configuration the pop-up structure may stand substantially transverse to the support surface.
