It's just a bomb!!! I don't know who invented it, but he's a genius! My son with the peculiarities of development, a special stroller is too much, and in the usual does not fit, we ride a lot of hospitals and often sleep on the way to a tawny Bogatyr dream. My child in 4,8, weight 18 kg, height 110.it fits freely on this piece and its growth is also normal! I can be wrapped in two. Freely fastens on a winter jacket. The only nuance, in the outer clothing a little slips and the belt itself, and the child, but still easier than on the hands. Back of course Bobo, but tolerable. Miracle thing, order and do not doubt. Delivery to Moscow 21 days. Almost walked along the seam, but not criminally, does not crawl further, the functionality does not affect.
