Abstract: Disclosed is a frame assembly for a folding type chair that are folded or unfolded once by coupling a plurality of upper and lower supports configuring a main frame of a chair to be operatively associated.

Abstract: The present invention relates to a folding table, and when the table is unfolded or folded, the table tops are connected by a hinge, and the legs placed inside the four corners are also linked to the operation, so that the table tops and legs are unfolded or folded at once. When the table is unfolded, the legs support all of the top plates by supporting the above corner plates, and include a pair of leg plates that are connected to each other when folded or unfolded through a hinge, and form a sliding rail to adjust the length of the leg.
