Is it any good? Going round in circles with pram choice again. Stumbled across these online and thought it looked pretty decent. Assume i'm right in thinking the carrycot and the car seat are one item which converts to do both jobs? Good for us as we often do long car journeys so handy to have a lie flat option for travel. Does the chassis take any other type of car seat (i.e. maxicosi cabriofix) out of curiosity? Any thoughts/advice on this one welcome!
