Hi, it's me milka!
I don't know mine is ST480 or not (I throw away the label & receipts). If the one u want is the one orange colour & with a leaf pattern on it - then don't buy la!
Mine is too small & too narrow for my bb (u saw her last time and u know her size is already not big la!). Even it is very light (weight) but I never fold it when using, so I think the weight of the stroller is not really very important.
