A foldable baby stroller chassis includes a pair of front legs with a plate pivotally connected to the upper end of the legs and a pair of back legs having upper ends pivotally connected to the plate. A member is provided having a lower end with a clamp connection to the lower ends of the front legs and an upper bent arm portion with an intermediate pivotal connection to the back leg. A rear seat portion having an intermediate portion pivotally connected to the upper end of the bent arm portion and a plate, which is preferably triangular in shape, is connected to the rear seat portion adjacent its lower end and has an apex projecting forwardly in which a handle is connected pivotally. A joining plate is provided on each side of the upper end of the back legs and pivotally connected to the upper end of the front legs and the upper ends of the back legs. A bushing is carried on each side of a handle and extends and is movable relative to the handle. The bushing inlcudes a limit engagement hook and a limit stub arranged and spaced at locations along the handle. The stubs are selectively engageable with the hook portions of the bushing to position the chair in selected adjusted position either folded or extended. In addition, the construction includes an armrest assembly made of a covering material with a connection piece at each end which fits over and is connected to the upper end of the front legs and the upper end of the bent arm portion of the strut leg. The armrest portion has a slot into which a peg of a guardrail is insertable and the peg is lockable in the slot by a latch which may be released by a headpiece which may be pushed. The construction further includes a seat bottom which is pivoted on a cross piece of the front leg and connected to the rear seat portion and includes a footrest plate extending outwardly and downwardly from the front legs.
