Yep -- it has a telescopic handlebar and fits in on it's "side" i.e. with the "face" of the pushchair up against the back of the back seat (if that makes any sense?!).
That's in a convertible with the parcel shelf in the upper position, though. I used to have a tin top but can't remember whether the shelf's lower than in the convertible or not. In the limit I guess you can remove the shelf, though...
