PROBLEM TO BE SOLVED: To eliminate such inconvenience that writing is performed while anything like a text is laid on unstably crossed knees when a memo is written while listening lecture sitting on a pipe chair at a place where tables are not set for a course of lectures or the like. SOLUTION: A simple table for a pipe chair is constituted so that a simple table can easily be attached to a frame of the pipe chair which is used before, while previously adjusting height of the simple table.
