Abstract: A portable mobile foldable table including a foldable frame having rigidly connected upper and lower side rails and legs, inwardly foldable end rail assemblies, and upper and lower trays which fit within the framework of the upper and lower side and end rail assemblies rigidly locking the frame in operating position. Shoulder surfaces along the side rails with an engageable relationship between the top edges of the end rail assemblies with end handles on the trays provides support at tray ends as well as support along the full lengths of the opposite sides of the trays. The spacing between the legs, side rails, and folded end rail assemblies provides storage space within the folded frame for two trays which are slightly longer than the distance between the legs at opposite ends of the frame assembly so that the trays rest on the folded lower end rail assemblies contained between the legs on opposite sides of the frame for tray storage when the frame is fully folded.
