A portable artist’s horse includes a pair of generally parallelepiped bench sections containing individual storage compartments which are hinged to provide a bench and pallet support in an erected configuration and to allow folding to a compact travel configuration which can be easily transported by pulling or pushing. The end member can include an end member wall with a first surface disposed toward the flexible wall and a second surface facing away from the flexible wall. Via the above module structure, the substrate can improve the function of controlling multiple systems. Because the memory used by such an object is freed for other uses by the application, overall application performance may be improved.
