ABSTRACT:
A two-component, interlocking foldable seat or support of cardboard, and the like, is provided from foldable blanks. Each component is folded into a closed, multi-sided shape and lightly locked together along its peripheral edges. Seating panels on each component extend from a rear sidewall, and are slotted to enable folding and engagement along corresponding slots of opposed sides.
The two components are interfitted along slots that are aligned with the seating panel slots. The seating panels are then folded and engaged along their respective slots to produce a stable platform.
