A B S T R A C T The invention relates to improvements in light-weight collapsible support structures in the nature of easels, book rests and the like which are self sustaining in a predeter- mined fully erected configuration, presenting in the fully erected configuration a multiplicity of forwardly facing panels upstanding in a rearwardly inclined or substantially vertical position to provide support surfaces for the dis- playing, supporting or anchoring of articles such as pads, books or the like and further presenting forwardly extending ledge portions from the bottom edges of such abuttment sur- faces, said ledges serving to rigidify and stabilize the erect configuration of these structures against collapse, but so adapted as to be foldable into a position allowing for such structures to be compactly folded up and collapsed for storage or for carrying when not in use.
