ABSTRACT:
A collapsible structure having front and back ends with front and back support members includes a single central support member to pass in a direct line along the cover and thus support the entire structure at roughly the center of the cover. The item may be sewn and easily manufactured in a fashion so that upon being collapsed it occupies the smallest possible volume and has no overlapping support members. Finally in pet toy applications crinkly material and washable material may be included.
