We have had this pushchair since our lg was born, we love it and have had no problems. Now she is almost 2, she walks most places and shorter journeys, however we still need to use it for holidays and going on long days out. We are using the seat that came with the pushchair which we have since been told is the first stage seat and apparently there is a second stage xl seat??? Some people say you must buy a complete new seat frame and others say the foam padding slides off and a thinner canvas type material cover can be brought to fit on the original seat? She will only be using it on occasions so won't be paying out for a new frame, but if it's just a different cover/lining it would be worth it. Anyone have a clue what option it is?
