The carriage has a pair of elongated handles each having an upper sleeve slidable therealong and each having a respective elongated front leg of the carriage secured to the associated sleeve. A pair of elongated rear legs have their upper ends pivotally connected to respective front legs intermediate the ends of the latter, and each leg has a support wheel rotatably mounted on its lower end. A respective lower sleeve is slidable along the lower portion of each front leg. An X-frame, formed by a pair of elongated arms pivotally connected intermediate their ends, interconnects the upper and lower sleeves, each arm having its upper end pivotally connected to the upper sleeve slidable on one handle and its lower end pivotally connected to the lower sleeve slidable on the front leg connected to the upper sleeve slidable on the other handle. Tie rods are connected at one end to each upper sleeve and are connected at their opposite ends to an operating knob. By upward or downward movement of the operating knob, the X-frame can be contracted or expanded to selectively collapse or erect the carriage or push-chair. A foldable seat back has wings connected to the respective tie-rods and also to the front legs, and a foldable seat is connected at its opposite sides to U-frames, each having one leg pivotally connected to a respective lower sleeve and another leg connected to the associated handle.
