A foldable support base includes a first board, a second board, and a third board. The first board has an edge forming a positioning section. A surface of the first board and a surface of the positioning section of the first board are provided with a first pad for protection against scratching. The second board has an edge that is in movable pivoting joint with an opposite edge of the first board. The third board has an edge that is in movable pivoting joint with an opposite edge of the second board. The second and third boards are provided with at least one second pad to protect against scratching and to prevent undesired movement. The above described arrangement helps, in either expanded or folded condition, reducing overall volume for easy carrying and protecting against damage caused by scratching and also providing a function of secure positioning and retention.
