A collapsible portable structure employs elongate side panels of a generally triangular shape, each formed by a flexible frame member within a retaining sleeve and fabric within an interior of the frame member. The elongate side panels thus form a pyramidal structure when in a non-collapsed position, the structure having an overall height that is greater than the width of any of the side panels at their widest point. Weights preferably at corner panels between bottom corners of adjacent side panels improve stability for outdoor use. The structure collapses into a substantially cylindrical shape.
