Abstract: A plastic-sandwiched framework structure for constucting a portable folding table. The structure includes upper and lower plastic table top halves and a framework grid sandwiched therebetween. The table top halves are bonded or cemented to one another. The framework grid is preferably made of wood, and includes joists or beam members interconnected by cross members. The framework grid is received in a correlatively shaped shell integrally formed in the lower half of the table top. Folding legs are mounted on the underside of the table top and connected through the lower table top half to the cross members. The lower table top half is provided with gussets at selected locations between relatively high vertical walls and the adjacent horizontal planar surfaces. Substantially all other interfaces between vertical and horizontal surfaces on the exterior of the lower table top half are provided with a radius. Stiffening ribs, which may be extensions of the shell, are also disposed on the lower table top half.
