The present invention provides collapsible folding furniture that overcomes the limitations of past furniture configurations to achieve strong and lightweight furniture structures that have full size features and comfort but that are extremely compact, easy to set up, and that have no loose parts. A collapsible furniture support structure has a support surface extending between at least two side braces, and at least two leg supports for maintaining the support surface in a substantially horizontal position. A separate socket joint is provided that corresponds to each leg support. Each socket joint is slidingly engaged with an upper end of a corresponding leg support and engaged with an end of a side brace. A separate elastic cord is provided for each leg support, with each elastic cord connected between a corresponding leg support and socket joint. Each cord has a length selected to be in a state of tension when the corresponding leg support is engaged with the corresponding socket joint, as well as to enable the corresponding leg support to be disengaged from the corresponding socket joint and pivoted about the socket joint to the support surface while the cord remains connected. This support structure configuration enables the folding and collapsing of the components into a compact bundle having no loose parts, for easy transport and storage. The tension in the elastic cords also results in easy set-up of the structure without requiring assembly of separate components. The support surface is provided as a flexible material sized to support a seated person or alternative, to provide, e.g., a table, cot, or foot rest.
