A linkage for a foldable high chair is capable of keeping in a use position by a locking mechanism, and then foldable by rotation of its chair back frame forward and downward. The foldable high chair comprises at least a front strut frame, a rear strut frame, a chair back frame, a seat support frame, a pair of arm rests, a first link, a second link and third link assembled by pivot means with each other and a locking mechanism capable of keeping the foldable high chair in a use position. The seat support frame is capable of driving by the chair back frame and then drives the first slidable connector through the first link and the third link, and then the first slidable connector drives the rear strut frame through the second link, so as to rotate the rear strut frame to close to the front strut frame. |
