Review calls it heavy and bulky, with low LATCH limits forcing a belt install relatively early.\nCybex Callisto G 360: The seat scored mid-pack overall in independent testing: easy installation and swivel convenience with a canopy were praised, but crash-test readings and weight were weak points.",
