Abstract: Easy to assemble and disassemble tables have continuous frame members with at least two tapered sockets which support table legs. The continuous frame members are identical and thus can be used interchangeably as table bases and table top supports. The center of each taper within the continuous frame member is in the same position. Tapered sockets within each frame member insure that legs inserted into those sockets are parallel to one another. The parallelity of the table legs is further enhanced by inserting the other end of the table leg into a corresponding frame member in which the tapers are identically spaced. The tables are easy to assemble by inserting the tapered table legs into the “self-holding” tapered sockets in the frame members. Easy disassembly of the tables is facilitated by quick release mechanisms which press the end of the leg seated in the socket to displace the leg from the socket.
