We have long wrestled with whether we still buy a seat reducer for the sports car or not. As our little girl was six months, however, with still no big / long enough to optimally seated and strapped in his sports car, we have brought ourselves to do so. Said in retrospect, this was not a bad decision. This seat reducer is put into the sports car. The pity is that you can still attach it somewhere, so it does not slip. It is positive that the headboard can be attached with Velcro so that the head support grows with the child. Remains positive that the straps of the stroller can be long out behind the headboard and on the shoulders only reappear without scratching the neck of the child.
