A collapsible chair frame includes two rear legs and two front legs. A cap is secured to a lower end of each leg. A sheath extends from each cap and continues to receive the related leg when the related cap is lowered beyond the related leg in a collapsed position of the collapsible chair frame. A lower ring is movably provided on each leg. A rear, upper ring is secured to each rear leg. A front, upper ring is movably provided on each front leg. A lateral rod includes a lower end pivotally connected to each lower ring and an upper end pivotally connected to each upper ring. A rear rod, longer than the lateral rods, connects a related cap to a related rear, upper ring. A front rod, as long as the rear rods, connects a related cap to a related front, upper ring.
