I really need to start folding my pushchair because of where i store it, as now the neighbour needs to store her pushchair in the same place, which is in the space underneath the stairwell in the block of flats we live in. But my pushchair will not fold down enough to engage the locking clip, the only time i could fold it down was when i took all the covers off to wash them, then it folded easily and really well and locked shut. Does this mean it has a design flaw and that the seat liner is too bulky and padded to fold it properly, would this be reason enough to get a refund/exchange? I have now seen another pushchair i would like to buy which is the chicco nunu which looks like it folds really easily and seems to fold down really small. unlike the pushchair i have at the moment. What should i do?
