A self-erecting structure consists essentially of a block of open-cell foam material, the outer surface of which has been sculptured into three-dimensional formations completely enveloped by an airtight skin. The structure can be pressed to expel any air or other fluid out of the foam material and any internal void through a bleeding aperture which is then sealed, thus keeping the structure into its collapsed state. Upon opening of the aperture, the foam bounces back to its original state sucking in ambient air and restoring the structure to its full size. Embodiments of the invention include three-dimensional displays, decoys, habitats, toys, and advertising props. The foam structure may be formed by molding, cutting spraying, or compressing. The airtight skin may be applied by molding, bonding, spraying or by singeing the surface of the foam.
