Claim:
A collapsible structure adapted to be supported on a support surface and comprising: a first panel, a second panel, a third panel and a fourth panel, each panel having a frame member that has a folded and an unfolded orientation and a fabric material covering portions of the frame member when the frame member is in the unfolded orientation; a first further fabric material having one end coupled to the fabric material of the first panel and another end coupled to the fabric material of the second panel, the first further fabric material extending between the first panel and the second panel in a manner such that the first and second panels are parallel to each other, and the first further fabric material oriented perpendicular to the first and second panels; and a second further fabric material having one end coupled to the fabric material of the third panel and another end coupled to the fabric material of the fourth panel, the second further fabric material extending between the third panel and the fourth panel in a manner such that the third and fourth panels are parallel to each other, and the second further fabric material oriented perpendicular to the third and fourth panels; wherein the first and second further fabric materials intersect each other to divide an interior area between the panels into a plurality of separated spaced, wherein at least one of the first and second further fabric materials having an opening to allow passage from one space to another space, and the third and fourth panels are perpendicular to the first and second panels.
