A portable, collapsible structure having a frame element disposed within a sleeve, defining a perimeter of at least one wall is disclosed. A roof is connected to the at least one wall at a seam, wherein a portion of the sleeve is connected to the seam, and wherein the roof and the at least one wall define an interior of the structure. The portion of the sleeve connected to the seam is disposed within the interior of the structure. The roof and at least one wall may further comprise a flexible material such as nylon, canvas, or polyethylene. Further, the frame element may additionally comprise a continuous band of resilient material. Such a band of resilient material may have sufficient flexibility to be coiled without breaking and sufficient resiliency to substantially return to and maintain its original shape. Steel may be such a suitable resilient material.
