Abstract

A foldable table-chair assembly and the frame thereof. The frame has a table frame and four integral chair frames. A table panel is able to be detachably attached on the table frame. The table panel has a plurality of hard sub-panels which are foldably connected together and a covering containing the sub-panels. A chair panel is able to be detachably attached on each chair frame. The invention is able to lower the attention needed to deal with each chair and the table and be folded up and opened by a simple operation thus saving the time of storing and preparing for using.
