A collapsible high chair for children comprises a frame, a seat portion, a backrest and an adjusting mechanism, all of which are sequentially connected with. The adjusting mechanism further comprises a pivotal member connecting the seat portion and the frame, a first engaging unit, and a second engaging unit. A sliding piece of the first engaging unit cooperates with two rods and makes the rods be escaped from the restriction of the pivotal member while a button of the second engaging unit cooperates with a cam and makes the cam be escaped from the restriction of the rib. Only when the rods and the cam are simultaneously escaped from the restriction of the pivotal member, the seat portion can be pivotally rotated relative to the frame. Also, the backrest can be rotated relative to the seat portion, so that the volume of the collapsed high chair is very small. Besides, the seat portion includes at least a movable piece with a bump for be engaged into the slits with different height at the arm of the seat portion to adjust the tray in height.
