The Manduca is simply thought brilliantly. In only 10sec my child is in the seat. ... Baby strap-in, shoulder straps drum, buckle to ... finish. And the child does not even have to be kept, since the arms are indeed up to go on to the buckle and no belt in the world can slip so down. The body contact is just right, not too tight, but tight enough that my child feels totally safe and blissful slumbers. Or with big eyes gets to know the world. I enjoy wearing my mouse so and I enjoy the freedom that one has thereby. Even after 3 hours wearing child does my back, my shoulders not hurt. Unfortunately I have to Manduca until my fourth child discovered since I took part in a study on child safety seats. I wish I would have had him in my 3 big already. He is of all seats I in this study so far tested the very best !!!! (Wholesale is not advisable from Baby Björn !!!)
