A highchair comprising a lifting means and a foldable leg frame is disclosed. The lifting means includes an operating rod, an outer tube and a piston rod. The operating rod can be easily operated by single hand pressing or foot tramping to adjust the height of the highchair. The leg frame comprises an upper pivoting portion, a lower pivoting portion and a plurality of sub-legs. Each sub-leg includes a first branch leg and a second branch leg pivotally connected to the upper and lower pivoting portion respectively. The upper pivoting portion is fixed on the outside of the outer tube of the lifting means. The lower pivoting portion is fixed on a lower portion of a sliding sleeve and can slide together with the sliding sleeve. With the axial sliding of the sliding sleeve on the outer tube, the leg frame can be folded into the minimum volume.
