A supporting portion for a foldable table or a foldable bench is described. The supporting portion includes a V-shaped assembly and a supporting brace. The V-shaped assembly includes two connecting rods and a sliding sleeve. Each of the connecting rods has a disconnected end and a connected end. The connected ends are connected to opposite sides of the sliding sleeve to form a unitary block. The sliding sleeve includes a front ring, a rear ring and a middle piece. The middle piece has a locking hole. The disconnected ends are rotatably connected to a pair of legs respectively. One end of the supporting brace is connected to the undersurface of the table or bench top, and the other end is adapted to slide through the sliding sleeve. The supporting brace has an elastic pin proximate to the other end. When the foldable table or bench is in unfolded position, the elastic pin is inserted into the locking hole.
