ABSTRACT:
A foldable furniture structure has a base which supports a load bearing sheet. The base is formed as a closed, foldable structure including two roughly parallel end sheets hingedly connected along corresponding edges by two sides, each of which is foldable along at least one intermediate vertical hinge. The base is thus foldable in a bellows-type motion between a closed state in which the two parallel end sheets are brought together with the sides folded between them, and an open state in which the two parallel end sheets are pulled apart. The load bearing sheet is hingedly attached to each of the upper edges of the two end sheets and has at least one intermediate hinge deployed parallel to the upper edges of end sheets. The dimension of load bearing sheet between the attachments to the upper edges of the end sheets is chosen to delimit a fully open configuration of the base such that the sides are opened to a bellows angle of no more than about 90.degree..
