We have a Römer Baby Safe II and the bag really fits class. It was much more practical purely to put our son in the sweater and then zuzuzippen than zwengen small only in a jacket and then in the seat belt!
So why not 5 stars?
At the bottom of the bag are Platiknoppen so that it does not slip so quickly into the bowl. After the first wash the studs have however partially begun to dissolve and then were individually in the infant carrier.
Since it was below the beanbag, but never was a danger that he gets the dissolved knobs in her mouth or in the hands! So no safety issue, but only a little ugly.
All in all, I would like the product but definitely recommend!
