BABYZEN created YOYO+ board to adapt exclusively to the YOYO+ strollers. Parents no longer need to carry their tired older child after shopping, to cross the road or when he/she starts to run around. Your child can safely hop onto the board, and choose to stand or sit on the easy-to-remove saddle. When it is not in use, YOYO++ board can be folded into space-saving storage positions. Features: -Compatible only with the YOYO+ stroller -Set in one click and one-handed -Can carry a child up to 20 kg / 44.1 lbs -It fits easily when installed on the stroller
