Abstract: Tables having tops (20, 22, 23, 24, 25, 26, 28, 30, 32, 34, 36, 38) with two or more edge portions designed to be adjoining edges. One adjoining edge is concave with a radius r. A second adjoining edge is convex with a radius r, less enough clearance to prevent binding as adjacent tables nest and rotate, one in the other, to form variable-angle assemblies. Any additional non-adjoining edge, or edges, give the designer great latitude in choosing practical and aesthetic shapes. Multiple identical tables can form curved or straight, open or closed, loop assemblies. Tables in assembly can be fastened to prevent horizontal separation.
