A foldable chair having three lower rods and three upper rods pivoted to a center part. A canvas seat is attached to the upper rods, and the lower rods engage the ground in the operative position of the chair. A rod vertically sliding in the center part is connected to the upper and lower rods for unfolding the chair and carries a cup-like locking head at its lower end. The rim of the locking head engages hooks on the lower rods to hold the same in the operative position, and locking rods connect the upper rods to a pivot head on the upper part of the sliding rod. Movement of the pivot head away from the center part is limited by an abutment on the slinding rod, thereby determining the operative position of the upper rods.
